[Qgis-user] QtWidgets.QFileDialog.getSaveFileName make qgis crash on windows 10

[PLASSOT Eric via QGIS-User]

Hi,
with qgis 3.34 with a processing script in pythonthe use of the dialog 
box QtWidgets.QFileDialog.getSaveFileNamemakes qgis crash on windows 10 
and not on windows 11.
Maybe because the dialog is initiated in C/Program Files\QGIS 3.34.4\bin 
which is a protected folder?I tried to set the document folder as 
default, but same crash.

the code :
 output_file_name = input_featuresource.sourceName() + '.kml'

output_file_path, _ = QtWidgets.QFileDialog.getSaveFileName(None, 
"Exporter les polygones au format KML",

output_file_name,
  "Fichiers KML (*.kml)")
I try this with the same crash when i click "Enregistrer"
 output_file_name = input_featuresource.sourceName() + '.kml'
 default_directory = os.path.join(os.path.expanduser("~"), "Documents")
output_file_path, _ = QtWidgets.QFileDialog.getSaveFileName(None, 
"Exporter les polygones au format KML",

os.path.join(default_directory,output_file_name),
  "Fichiers KML (*.kml)")

The crash message :

Re: [Qgis-user] Export to GML in 3.28?

Hi Evan,

Thank you for the information, the document was very helpful.

Since the default changed to GML3.2 do you think the FORMAT dropdown should 
include a GML2 option? I am not sure if this was missed or if this was done by 
design.

Re: [Qgis-user] Convert an ALOS PALSAR DEM from ellipsoidal to geoid.

[Fielding, Eric J (US 329A) via QGIS-User]

Hello Eddison,

I am not sure what source you are using for the ALOS PALSAR DEM that you are 
describing. As far as I know, there is no systematically processed DEM made 
from ALOS PALSAR data. There is a DEM composite that the Alaska Satellite 
Facility (ASF) is using for their Radiometric Terrain Correction (RTC) 
processing of the ALOS PALSAR that they have resampled from other sources. See 
their web page for details:
https://asf.alaska.edu/data-sets/derived-data-sets/alos-palsar-rtc/alos-palsar-radiometric-terrain-correction/#dem_information

The web page explains that they were using the SRTM1 (1-arcsecond or about 30 
m) DEM interpolated to the 12.5 meter spacing of the ALOS PALSAR RTC products. 
The SRTM DEM has the EGM96 geoid reference. I think they may recently have 
changed to using the Copernicus GLO-30 DEM that is also 1-arcsecond spacing but 
uses the EGM2008 geoid reference. Again, they will interpolate it to the 12.5 m 
spacing for their ALOS PALSAR RTC processing. Over the USA, they used the USGS 
NED DEMs that are higher resolution.

If this is the source of the “ALOS PALSAR DEM” that you are using, you will be 
better off getting the original DEM for your area from either the Copernicus 
GLO-30 DEM sources (there are several) or the USGS NED DEM sources. You will 
still have to do the geoid to ellipsoid height conversions but it won’t be 
modified by the interpolation that ASF is doing in their RTC processing.

Re: [Qgis-user] Tectonic plate boundaries

Hi John,

Here is a GitHub site with plate boundaries in several GIS formats, including 
Shapefile and GeoJSON. 
https://github.com/fraxen/tectonicplates

These should work with QGIS. This is from the Bird (2003) paper that is a 
widely used source of tectonic plate boundaries.

I believe you have a basic misunderstanding of the nature of data within a
GIS.

Generally the way QGIS (and most GIS) works is they "take" only data such
as points lines and polygons and then the user develops styling on those to
create the desire cartographic effect.

It would be most unusual to find shading or text in a shapefile.

Test in a shapefile is an attribute of some geometric feature. So line 377
might have an attribute that is "Mid Atlantic Ridge".

QGIS provides the ability to print the text attributes as labels, which can
be styled in many useful ways for visualization purposes.


Everything I do find is rejected by QGIS as not being in a suitable format.

[Qgis-user] QgsLayoutExporter and Raster Layers

[Eric Younkin - NOAA Federal via Qgis-user]

Hello,

I am using the QgsLayoutExporter to build a screenshot of my QgsMapCanvas
view, following the code in the Quick Print plugin (
https://github.com/MarcoDuiker/QGIS_QuickPrint/blob/d1c946a7b6187553c92ffad7a0cc23d39a1bc593/quick_print3.py
).

I build the QgsLayoutItemMap as follows (including only relevant lines):

map = qgis_core.QgsLayoutItemMap(layout)
...
mylayers = self.project.mapThemeCollection().masterVisibleLayers()
map.setLayers(mylayers)
...
layout.addLayoutItem(map)
...
exporter = qgis_core.QgsLayoutExporter(layout)
exporter.exportToImage(fil,
qgis_core.QgsLayoutExporter.ImageExportSettings())

mylayers correctly lists the layers that I have loaded in my application.

(wms)>]


Each of these layers correctly shows in the screenshot, with the exception
of the first one, the vsimem based raster layer. This layer shows in my app
in the canvas, but is missing from the screenshot. I have tried exporting
that layer by itself, messing with renderers and opacity, etc. I can't seem
to get the vsimem raster layer to show in the screenshot. I thought the WMS
raster layer was going to be an issue, but it shows just fine.


Is there any issue with vsimem gdal layers? Should this layer work, if I
can visualize it on the canvas in my app? I can't figure out where to go
next to diagnose this issue.


Thanks, Eric

[Qgis-user] QGIS exported layers lose defined CRS definition

[Eric Seymour]

Hello,

I have layers stored in a Spatialite database with a defined CRS of 102707 (
https://spatialreference.org/ref/esri/102707/). When I select features from
this layer and export them back to the database from within QGIS (3.4.4),
using the same CRS, the resulting layer has a CRS of USER:11. The
parameters are the same, e.g., the same latitude of origin, but I want the
exported tables to be clearly identified with the 102707 CRS. I have never
encountered this problem with other CRSs. Does anyone have any idea why
this would happen for some CRSs?

[Qgis-user] MacOS X11 library configuration for plugins

[Fielding, Eric J (US 329A)]

I recently upgraded from QGIS 3.10 to 3.18.3 to get the excellent new 
continuous color palette plotting for map layouts. That is a huge improvement 
for people like me who work with continuous datasets. Thanks to those who 
implemented this!

I am getting warnings from several of the QGIS plugins that they are not able 
to find an X11 library. It seems that the plugins have been compiled to look in 
a different location “/opt/X11/lib” than what I have on my Mac. I installed my 
X11 with MacPorts instead of the XQuartz server version, so this library is at 
“/opt/local/lib/libxcb.dylib” on my system. This is the error message:
ImportError:

Is there a way to update the path in the plugins or do I have to install the

[Qgis-user] NDVI resolution

[Fielding, Eric J (US 329A)]

Neels,

The Worldview-3 satellite has different resolutions in the different bands. 
There is a panchromatic band that has 31 cm resolution, but the multispectral 
bands have 124 cm (1.2 m) resolution. You are probably seeing objects with the 
panchromatic band, but NDVI has to use the coarser multispectral bands.

Some of the Worldview data products use the panchromatic band to "sharpen" the 
multispectral images, but the multispectral data is fundamentally four times 
coarser than the panchromatic bands. If the multispectral bands have been 
resampled (interpolated) to the 31 cm pixel size to match the panchromatic 
band, they will be fuzzier.

Yes, the raster calculator, and the extent (resolution, nr of  pixels, 
everything)  of the output file matches that of the two input bands. What is 
interesting is that I noted that the boundaries of some man-made objects  do no 
show this fuzziness:

[Qgis-user] Issue with "Mesh Calculator" with a GRIB file

[Eric Compas]

All,

I'm experimenting with the mesh viewing and analysis tools in QGIS (3.12.3)
using both the Crayfish and QGribDownloader plugins. All's going very well,
and for the most part, the tools are relatively easy to use.

While I've gotten several "Mesh calculator" expressions to work correctly
with a GRIB file (downloaded using the QGribDownloader plugin), I'm running
into an error with any expression using precipitation group, e.g.:

("Temperature [C]" > 10) and ("03 hr Total precipitation [kg/(m^2)]" < 2)


This expression yields an error "Mesh calculator: Invalid or incompatible
datasets used." I've tried several permutations and start/end ranges. All
without luck.

Investigating further, it seems like the number of time "slices" in the
precipitation group isn't the same as in the temperature group and may not
be handled correctly in QGIS (??). In the temperature group layer
properties, the time slider and metadata times are always the same
(synchronized).  For the precipitation group, the time slider and metadata
in the layer properties aren't in sync:

[image: 2021-02-06_10-34-02b.gif]
I suspect that the precipitation group has fewer time "slices" that may not
be handled correctly and hence the error in the "Mesh Calculator" tool.

Is this a user error or some issue with how the mesh tools handle groups
with differing number of time "slices?"

I'd appreciate any help.

Thanks,

Eric

Re: [Qgis-user] Lat Lon Tools question

[Eric Sorensen]

As Greg and others point out, I appear to be using the UTM zone term 
inappropriately.  My apologies.

What I am after in my label, is the MGRS flavor that includes the latitude 
band, and agrees with the image shown in this link;

https://docs.qgis.org/3.4/en/_images/utm_zones.png 
<https://docs.qgis.org/3.4/en/_images/utm_zones.png>

After you folks successfully educated me on this, I came up with the following;

concat(name, ', ',  mgrs_gzd($Y, $X), ' ',   format_number(utm_east( $Y, $X), 
0), ' ',  format_number(utm_north( $Y, $X), 0))

Which gets me a label like this for the point I originally supplied;
Park, 13S 384,258 3,974,547

This is how my Garmin GPS displays coordinates of waypoints (sans the commas), 
and how someone would input the point into their gps, after I hand them a map I 
have created in QGIS.  Now to eliminate the commas.

Thank you all for your input,
es

I’ll have to disagree with you Chris.  Zone 13N has a southern boarder that

[Qgis-user] Lat Lon Tools question

[Eric Sorensen]

Hi,

I have waypoints from a Garmin GPS that I import from a gpx file into a vector 
layer.

In the gpx file, they are of the form;

  
2262.18896499826
2021-02-05T18:03:05Z
Park
Flag, Blue
user

  
SymbolAndName

2021-02-05T18:03:05Z
  

  


They appear in the correct location in my project.  Now, I am trying to display 
a label at each point using rule-based labeling with the following expression;

concat(name, ', ', utm($Y, $X))

The labels appear as expected, except one small problem.  I know the points are 
in UTM zone 13S, yet the label shows zone 13N.

Any thoughts on what I am doing wrong.

[Qgis-user] Visualizing multi-page GeoTIFF in QGIS

[Eric Younkin - NOAA Federal]

Hello,

I have a GeoTIFF that I have created in the following manner:

gdal_translate first_grid supergrid.tif

gdal_translate second_grid supergrid.tif -co APPEND_SUBDATASET=YES

Dragging this into QGIS appears to only allow me to visualize the first
dataset used. Is there some option to allow me to view all added pages?
This does seem to work if I use a GeoPackage instead of a GeoTIFF.  I can
also pull in a VRT for these TIFFs and that works.  I'm going the
APPEND_SUBDATASET route to construct one TIFF file that will work with PROJ
vgridshift, which appears to support multipage TIFFs.

Thanks,
Eric

Re: [Qgis-user] Loading up .grd files into QGIS

[Fielding, Eric J (US 329A)]

Hi ajwchile,

I know of two types of geophysical files that have the .grd file extension for 
gridded datasets. One is the Surfer Grid and the other is the Generic Mapping 
Tools (GMT). I use GMT software all the time, and QGIS and GDAL usually have 
that GMT format included as an option.  

Does the "gdalinfo" command recognize the format? If it does, then GDAL and 
QGIS should be able to read it. If "gdalinfo" does not recognize the format, 
then it is possible the files were corrupted somehow.

Best,
++Eric Fielding

Re: [Qgis-user] [EXTERNAL] Re: 2019 USGS 7.5min topo sheets

[Fielding, Eric J (US 329A)]

I was able to open a USGS GeoPDF for a 2018 map of Pasadena, Calif. with Adobe 
Acrobat (and Acrobat Reader) and it loaded quickly. The file is a vector file 
with all the line work stored as vectors. I was also able to open it in Adobe 
Illustrator, but that was slower. Illustrator sees the GeoPDF with only one 
layer, but has a huge number of vector lines for all the contours. I don’t see 
a raster layer in Illustrator. QGIS 3.10.3 on my Mac was not able to open the 
GeoPDF as either a Raster or Vector database.

I also noticed that opening the folder with the GeoPDF in Adobe Bridge caused 
the Bridge program to allocate 19 GB of memory, which is not very helpful on a 
laptop with 16 GB of RAM. I had to quit Bridge to get the memory back. This is 
probably similar to what people noticed with keeping the GeoPDF on the Windows 
Desktop.

From the “Font not available” warnings in Illustrator, I see the GeoPDF must be 
created with an ESRI program as some of the fonts had ESRI in the name. I 
assume that ESRI ArcGIS can open the GeoPDF.

I am running Qgis 3.4.2 on Windows and I can load the new style geopdf USGS 
7.5' quads, including the imagery layer.
It's slow and grinds qgis to a halt while it loads, but it does work. The 
different layers, which are independently controllable in Acrobat Reader are 
flattened when the topo is opened in Qgis, which rasterizes the image and 
presents it as one raster, not separate layers.
USGS has made these maps much less useful by adding the aerial imagery layer, 
at least for me. Qgis isn't the only application that flattens the layers, and 
the imagery obscures way to much for my taste.

will not open and gives error "Missing Codec".

Very surprising.  I know from past experience that
Global Mapper v6.04 will view TIF files that have
been converted from GeoPDF via GDAL.

Hello, low skill user here on QGIS 3.2.3 on Microsoft 10.   I have been 
using USGS 7.5' topo map as base layers for a couple of years.  My 
latest download, of amap sheet created on 12-18-19 will not load.  Error 
message is "Invalid Data Source"  Also of note is that the new map is 
much larger than earlier versions. 40mg vs 15-20mg.  Is this an 
intentional change by USGS or an error formatting the file.

[Qgis-user] Request for help with style control for lat/long grid and marker points (Eric Delson)

[Eric Delson]

Hello, I posted this request about 10 days ago but have had no comments 
or responses, perhaps I was unclear that I wanted help, so I am trying 
again.


I am making maps for publication in journal articles using QGIS (3.12) 
and Natural Earth base data. I have two questions:


How do I control the appearance (presence/absence, line style, labeling) 
of latitude/longitude "graticule" lines? I was able to change the name 
of the Equator in the Attribute Table, but not the placement of the 
label or other features.


I am placing a series of point markers from an imported Excel file of 
decimal latitude/longitude coordinates, with each point having a place 
name and category (time bins). How do I control the label, size, symbol, 
and color of each point, either by reference to its category or 
individually if necessary?


I have an earlier version of such a map made by a colleague in ArcGIS, 
which I can send offline if any of you wishes to see what I am seeking.


Many thanks, Eric Delson (Professor of Anthropology, City University of 
New York)

Ämne: [Qgis-user] Experiences using QGIS + PostgreSQL/PostGIS in a multiuser 
environment?

Hello QGIS:ers

I am evaluating setting up a server running PostgreSQL/PostGIS for use as data 
sharing/collaborating environment for spatial data. The user group may consist 
of up to 15 people, mostly using QGIS but one or two may use other software 
(non OS). Data is almost exclusively of vector type. The use is within a single 
organization.

I understand some people in this list have experience with this kind of 
environment and would appreciate if any of you would share any useful 
experience, challenges, thought or things to watch out for. I understand basic 
management routines are critical (user management, user rights), as well as a 
sound backup and update strategy. I also understand that proper data management 
procedures have to be in place, like rules for table creation and eventual 
deletion, attribute selection, etc. But what else can go wrong with this kind 
of setup if not managed properly? 
Thoughts and experiences welcome!

Best regards and thanks in advance

Hernán

readable by GDAL. The QGIS downloads should include GDAL, but perhaps you did 
not install GDAL during your QGIS installation? The other possibility is that 
you have GDAL installed but the file was corrupted at some step.

I can see that band two has ColorInterp=Undefined. I don't know what that means.

The GeoTIFF file is automatically generated by some SAR interferometry 
processing scripts we have and it is over 300 MB. The direct link to the file 
is:

Eric,

Can you provide a sample 2 band raster file?
Also what does the Information tab in the layer Properties show (should
be similar to gdalinfo)?

I'm wondering if it thinks your 2nd band is an Alpha/Mask layer and
treats it differently.

Thanks,
Alex

Re: [Qgis-user] trying to convert geotiff UTM toWGS84

[Eric Fielding]

If you want to change the projection of a raster image in QGIS, you need do a
reprojection by using the Raster->Projections->Warp (reproject) command that
sets up and runs the "gdalwarp" command. The "gdal_translate" command only
changes the format of a raster image. You have to use "gdalwarp" to do the
reprojection into a different projection.

Re: [Qgis-user] QGIS UTM projection of longitudes > 180 degrees

[Eric Fielding]

Nicolas,

Thanks for the suggestion. I am trying to use "save raster layer as" in
QGIS, but it is getting the extent of the data completely wrong in the UTM
zone 14 coordinates. It seems that QGIS (2.18.2 is what I have now) is
confused about the location of raster data at longitude > 180 degrees. I
will try to change the projection outside QGIS with "gdalwarp".

[Qgis-user] QGIS UTM projection of longitudes > 180 degrees

[Eric Fielding]

I have some geophysical data (subducting slab depth) that is stored in NetCDF
raster format (from this download site 
https://earthquake.usgs.gov/data/slab/models.php
  ). I am working with the
file that is for Mexico and Central America in a regular WGS84
longitude-latitude grid (CRS EPSG:4326), and it has the longitudes all as
positive numbers, i.e. from 254 to 279 degrees. When I load this in QGIS and
plot it in the original EPSG:4326 projection, it plots in the positive
longitude as expected. When I try to use the on-the-fly CRS transformation
to plot the map in UTM zone 14 (EPSG:32614), the raster does not plot. I
have other data in CRS 4326 (raster and vector) that has negative longitudes
and that plots in the UTM zone 14 map view. When I do plots with the Generic
Mapping Tools (GMT) software, it does not care whether the longitudes are
negative or > 180 degrees. Do I need to shift my gridded data to have the
negative longitudes to work with it in QGIS?

Thanks, the stylesheet fix worked and I can now see all the plugins in my
Chrome browser as an HTML page. 

QGIS plugins manager still says that the repository is unavailable on my Mac
computer, even after I restarted QGIS and pressed the "reload repository"
button. Maybe my home ISP is blocking some part of the protocol for the QGIS
application.

[Qgis-user] Plugins repository unavailable for 2.18?

[Fielding, Eric J (329A)]

Hello,

Has something changed about the plugins repository for version 2.18? I have not 
yet upgraded to version 3.x, and sometime in the last month or so the plugins 
repository (https://plugins.qgis.org/plugins/plugins.xml/?qgis=2.18) has 
stopped working for me.

Thanks,
++Eric Fielding

Re: [Qgis-user] Pyspatialite installation issues on Fedora 25

[Eric Goddard]

Hi William, I had the same problem on Fedora 25 and solved it with
comment 5 at https://bugzilla.redhat.com/show_bug.cgi?id=1340535.
Create a pyspatialite.py file in ~/.qgis2/python with the following
contents:

from sqlite3 import *

def connect(*args, **kwargs):
import sqlite3
db = sqlite3.connect(*args, **kwargs)
db.enable_load_extension(True)
db.load_extension("mod_spatialite")
return db


and processing should work.

Hope that helps!

Re: [Qgis-user] QGIS Viewer

[Eric Goddard]

If you're using the OSGeo4W installer, you could uninstall the filegdb
api so that QGIS has to use the OpenFileGDB driver (which is read
only) to view file geodatabases. The QGIS stand-alone installer just
has the OpenFileGDB driver, so nothing extra is required there.

Re: [Qgis-user] Lookup Tables in File GDB?

[Eric Goddard]

You're correct, the feature class is using a lookup table (domains in
ArcGIS) that the ogr drivers can't access as far as I know. If you can load
the gdb in ArcMap, you can use the Domain to Table tool (
http://desktop.arcgis.com/en/arcmap/10.3/tools/data-management-toolbox/domain-to-table.htm)
to export the lookup codes/values for loading into a Postgres table.

Hope that helps!

Re: [Qgis-user] creating a python plugin to autopopulate some of the Georeferencer properties

[Eric Goddard]

Problem solved, triggering from the raster menu didn't work, but going
through the raster toolbar did work.

for action in iface.rasterToolBar().actions():
if action.objectName() == 'mActionRunGeoref':
georef = action

georef.trigger()

Re: [Qgis-user] creating a python plugin to autopopulate some of the Georeferencer properties

[Eric Goddard]

Thanks Nathan, looking forward to 2.16 :)

In the meantime I'm working on a plugin similar to the ArkPlan
georeferencer (using the GeorefGraphicsView from ArkPlan) , but I'm
going to temporarily use the hacky solution until I can get that
finished, which brings me to my next question:

If I I iterate over iface.rasterMenu().actions() and print each item's
objectName, the only ones that show up are
mActionShowRasterCalculator, mActionShowAlignRasterTool, and settings;
the rest are empty strings. If I print each item's text, I get the
menu text for each submenu on the rasterMenu, so the Georeferencer
shows up as "". How do I access the actions on the
submenus within the rasterMenu()?

Just out of curiosity I did the same iteration over
iface.rasterMenu().children(), which lists only one QMenu object
(Terrain Analysis).

Thanks for all of the feedback!

Re: [Qgis-user] creating a python plugin to autopopulate some of the Georeferencer properties

[Eric Goddard]

Awesome, thanks John. We have about the same number of images to georef so
that will be a big help. I looked at the georeferencer code which is how I
discovered that some of the properties were stored in QSettings. I'm not
too familiar with c++ though, but since the qgis api can be used to do
custom applications I was hoping for a constructor for the georeferencer
that I could use.

It looks like I can make sure most of the settings are configured
properly using QSettings(), but still not sure how to go about opening
the georeferencer with an image and the output and report fields
pre-populated.

Hi Nicolas,

Thanks for the feedback. The script solution won't really work for us since
we don't have pre-existing GCPs to use in the scripts. We need to use the
georeferencer so we can place and make adjustments to the GCPs.

[Qgis-user] creating a python plugin to autopopulate some of the Georeferencer properties

[Eric Goddard]

Hi All,

I'm working on a project that involves georeferencing many historic
images. We'll have several people working in tandem, so to speed
things up and reduce errors I'd like to create a qgis python plugin
that, based on the source folder they select, auto populates the gdal
transformation settings such as the transformation type, resampling
method, target srs, output image and report paths.

I'm having some trouble working through the QGIS API documentation
though; does anyone know if it is possible to launch the georeferencer
window and set some of the transformation settings from python? So far
I've only been able to find examples of opening a processing tool's
GUI from python.

Thanks!
Eric

Re: [Qgis-user] Stacking Landsat Bands

[Eric Goddard]

Hi Jonathan, Did you try the GDAL merge tool (Raster - Miscellaneous
- Merge)? If you check the layer stack box it will create a multiband
image with any number of input files.

 I'm not familiar with the Orfeo tool but I use the SAGA Rgb Composite tool
 under SAGA\Grid-Visualization\ to stack Landsat scenes. It limits you to
 three bands which is a bummer, but works well. The tool output is rescaled
 to 8-bit, so you shouldn't use the stacked imagery for change analysis
 later, but it’s great for visualization.
 The GRASS Raster tool r.composite will also stack, but the SAGA tool seems
 to handle Landsat 7 SLC-off data gaps better.
 I’m new to QGIS, so some of the above might be wrong...

Re: [Qgis-user] Partitioning an Ortho?

[Eric Goddard]

Keep in mind that you need to have a license to write to sid files. If you
only have the license to read sids, when you partition your existing 4GB
sid, the output will most likely be geotiff which isn't as compressed as
sid so the overall file size may be larger.

Re: [Qgis-user] Problem opening .GDB (v 10.1) using QGIS

[Eric Goddard]

I have gdal built with FileGDB support and I was unable to open the
geodatabase; QGIS gave an invalid datasource error. Arcpy reports that
it is indeed a version 10/10.1 database though. Using

ogrinfo -al FWA_LINEAR_BOUNDARIES_SP.gdb

reports that it was successfully opened:
INFO: Open of `FWA_LINEAR_BOUNDARIES_SP.gdb'
  using driver `FileGDB' successful.

However, it should have also printed detailed information about the
feature classes in the geodatabase, which it didn't. Not sure what is
going on in the gdb. I was able to open it with ArcMap (checked the
version with arcpy).

 There you will find 4 zipped files. Download the smallest of them and let

 FWA_LINEAR_BOUNDARIES_SP.gdb.zip


 ogrinfo -al just reports:

 I'm able to open other FileGDBs. I wonder if someone with ArcGIS can open

Re: [Qgis-user] Problem opening .GDB (v 10.1) using QGIS

[Eric Goddard]

In another thread about QGIS and FileGeodatabases, there is a link to
the OpenFileGDB driver [1]. It mentions a different type of
compression that the fileGDB API doesn't support. It doesn't appear
that the FWA_LINEAR_BOUNDARIES_SP.gdb has that type of compression so
it should be able to load in theory.

I tried opening the GDB in QGIS and got the red bar at the top with
the invalid data message like you. Once that failed, we both used the
ogrinfo (QGIS uses the OGR library to read FileGDBs) command line tool
to see if OGR could open the geodatabase. It said it could, but it is
failing because it did not report detailed information about the
feature classes in the the database like it should have since the
'-al' flag was used. Since OGR can't open the file geodatabase, QGIS
can't read it.

Re: [Qgis-user] Selecting rasters with vector layer

[Eric Goddard]

Hi asher, if you go to raster - miscellaneous, there is a menu entry
called build virtual raster catalog. You can use that to virtually mosaic
all of your ECW files. This tool creates a new file you can load in as a
raster that references all of the individual ECW files to display them
seamlessly in qgis without having to spend the time to actually mosaic all
of them together. Load the resulting vrt file into qgis using add raster
and clip the vrt to your polygon layer using raster - extraction -
clipper.

Yes, you should be able to choose ECW from the files of type drop down in

You will need to remove the --with-postgres=yes and

sudo apt-get install flex

on the command line before configuring.

It sounds like you didn't get all of the packages in the dependencies
section installed; many of the development packages should have been
installed with the build-essential package. bison and ncurses-dev are
also in the list and will take care of the curses error., and the
libxmu-dev package will fix the X error. Did you paste the whole chunk

In Ubuntu 13.04 opencl is provided by the opencl-headers package. You

remove --with-opencl=yes from the configure options.

Hmm, I don't think you could've made it past the compiling gdal steps
if the geotiff package wasn't installed. In the cmake window for
configuring libLAS, do you have Values for GEOTIFF_INCLUDE_DIR and
GEOTIFF_LIBRARY? I have /usr/include/geotiff and /usr/lib/geotiff.so,
respectively.

Keep in mind that if you only want to compile QGIS you don't have to
compile LASzip, libLAS, or GRASS 7.

Re: [Qgis-user] MrSID raster and QGIS in linux

[Eric Goddard]

It isn't strictly true that you're crap out of luck--you just have to
download the mrsid API and register it with ldconfig. Depending on
your system, sometimes there are gdal plugins that you can then
install. This is how it is setup on Debian based systems. If there
isn't a plugin available, then you have to compile gdal with MrSid
support. Because MrSid is proprietary, gdal can't be distributed with
support built in. I wrote a guide for some friends for compiling the
GIS stack with MrSid/ECW support, but it is for ubuntu-based systems.
I'm posting the link here, perhaps it will help in getting it set up
in Fedora. Most of the actual compilation instructions should work,
but the dependencies and paths will be different.

 around with building sid support into gdal (which is another long story).

 The best you can do is to decompress the image using the Sid decoder
 (downloaded from Lizardtech). Just hope you don't have an overly compressed
 sid image that blows up to 160GB on decompression.

 The next best thing we could do is figure out some way to get this back into
 linux. If I had the coding chops I would do it...since I'm diving into
 fantasy currently I would also date Jennifer Lawrence.

[Qgis-user] Selection tool outline color

Hi all,

When using the selection tool in the map canvas, I can't see the light gray
color of the bounding box against my data. Is it possible to change this
color? I was only able to find an option to change the rubberband color for
measurements and the color of the selected features.

Re: [Qgis-user] Selection tool outline color

[Eric Goddard]

Hi Lene,

I'm not concerned with the colors of the features themselves, but with the
very light gray selection box when using the select by polygon tool. It is
difficult to see what is being selected when the features have light
colors, and its always difficult to see the line on a white background. See
attached image for clarification. I've searched the web and scoured the
settings with no luck. I don't think it can be modified at this point, but
that would be a nice feature.

Re: [Qgis-user] Executing qgis after building from git results in errors and warnings

[Eric Goddard]

For the python console, you need to install qscintilla. On 12.10 I
installed libqscintilla2-dev and python-qscintilla2. The dev package may
not be needed, but it works for me.

The python libraries are located in the $INSTALLPATH/share/qgis/python
directory. Add that directory to your python path to import pyspatialite
outside of QGIS. From within a python script you can :

import sys

sys.path.append(r/home/tgrossen/Apps/QGIS/share/qgis/python)

from pyspatialite import dbapi2 as db


Hope that helps.

 2. Question: I explicitly compiled pyspatialite, now where do I find this

 outside of QGIS too?

Re: [Qgis-user] Advice Please

[Eric Goddard]

This issue can be solved by acquiring an accurate reading with a sub-meter
GPS unit on your site grid's datum and using the affine transformation
tools to move the site grid data into a projected coordinate system based
on the difference between the GPS and site grid coordinates. The accuracy
of the transformation depends on the size of your study area. The results
were excellent when I used this process for grids a few hectares in size.


The affine transformation tools can be installed from the Plugins menu.

  Hi Bill,
 
  Can it be done? Yes, why not ?
  How? Well, firstly you should ask archeologists how they use whatever
  software to draw archeological features. The basic concepts will be the
  same i guess.
 
  I have no idea of measurement in general and of archealogical
 measurement
  in particular, but i will try a wild guess:
  I think that you always have to start from a fix point with known
  coordinates.(Point layer, which coordinate system?)
  From this, you can generate a grid e.g. mesh width 1 m (Vector-
 Research
  Tools - Vector Grid)(Line or polygon layer)
 
  Then you create your new layer(s) for your feature(classes) and start
  drawing.(Points, lines, polygons?)
  Of course there are dozends of steps to reach that phase, but i can't
  write a book here.
 
  As far as i know Access mdb still isn't supported yet (at least not
  available for beginners with no computer wizadry background), but you
 can
  export your tables to dbf format (direct import with drag and drop) or
 xls
  (through xytools plugin)
 
  More detailed questions, maybe more detailed answers.
  Maybe others with can drop in ...

Re: [Qgis-user] Newbie with request for advice

[Eric Goddard]

Before you can compile the samples or compile GDAL with FGDB support you
have to link the FGDB library so the system can find it. Before running
make in the FileGDB_API/samples directory, create a text file in the
/etc/ld.so.conf.d/ to hold the path to wherever you FileGDB_API/lib folder
is located and run ldconfig to update it. On Ubuntu executing the following
lines in bash should fix it:

sudo sh -c echo '/path/to/FileGDB_API/lib'  /etc/ld.so.conf.d/fgdb.conf
sudo ldconfig

after that, make should work.

  Hi Art,

 So I've got QGIS running on windows and linux. I haven't tried to compile
 file geodatabase support into my linux install (that's on my list to do).
 On my windows install I'm running OSGeo4Win - adding file based geodatabase
 support was easy - I just added the module and had support (I'm currently
 on my linux machine and not near my windows machine - or I would tell you
 exactly what I added).

 My windows machine is running Windows 7 64bit - my linux machine is
 running xubuntu. I own a consulting business and have ArcGIS running on my
 windows machine. There's not way I'm ever going to windows 8. So I'm
 sticking with windows 7 for ESRI and migrating as much of my workflow over
 to linux as I can...as I tell people - A clip is a clip and a buffer is a
 buffer. So I'll do what I can on linux and when I have to go with ESRI I'll
 jump over to windows.

 Now that I read all of this - I should really try to compile file based
 support on this laptop over the weekend.

 Below are the steps I use to add File Geodatabase support to gdal. This
 worked on Ubuntu 12.04 64-bit, but it doesn't use the deb source packages.
 Since you have a 32-bit ubuntu install, you need to download the 32-bit
 version of the FileGDB API. I tried to answer your questions as they come
 up in the steps I list below, so you may want to read through the whole
 thing before starting. Sorry for the length, but I hope it helps!

 In terminal:

 1. Change directory to wherever you downloaded the FileGDBAPI: *cd
 path/to/FileGDBAPI_download*

 2. extract the archive:* tar zxvf FileGDB_API_1_2-32.tar.gz* NOTE:
 Since you are using 32-bit Ubuntu, you need to download the 32-bit FileGDB
 API.

 3.You need to build the samples to make sure the API works. Change to
 the FileGDB_API samples folder: *cd FileGDB_API/samples*

 4. type *make*

 5. Run a sample to make sure it works. Change directory to the bin
 folder inside samples: *cd bin *, and then type *./Querying*. You'll
 get a bunch of text in terminal, just make sure it doesn't spit out any
 errors.

 6. If the sample runs successfully, you have a working FileGDB API and
 you are ready to compile GDAL. I like to move the FileGDB API to a better
 location than the downloads directory, but it is up to you. If you choose
 to move it, you can use the paths listed below. If you use your own
 location, change the path in the commands below

Re: [Qgis-user] How to compile gdal with ESRI FileGDB

[Eric Goddard]

Hmmm, I didn't get any errors like that when I installed so I'm not sure
what could be causing it. Do you have the build-essential package installed
that provides the necessary compile tools?

 6. If the sample runs successfully, you have a working FileGDB API and
 you are ready to compile GDAL. I like to move the FileGDB API to a better
 location than the downloads directory, but it is up to you. If you choose
 to move it, you can use the paths listed below. If you use your own
 location, change the path in the commands below to whatever you used. *sudo
 mv your location/FileGDB_API /usr/local/*

 7. Create a LD configuration file so that gdal is able to find the FGDB
 libraries: *sudo echo /usr/local/FileGDB_API/lib 
 etc/ld.so.conf.d/fgdb.conf *

 An explanation of ld is below.

 8. run ldconfig to update the linked libraries: *sudo ldconfig*

 You're now ready to download and configure gdal.


 1. Download gdal from http://download.osgeo.org/gdal/gdal-1.9.2.tar.gz
 2. Extract the contents of the gdal archive: *tar zxvf gdal-1.9.2.tar.gz*

 3. Change to the gdal directory: *cd gdal-1.9.2*

 4. Now gdal needs to be configured. Your configure line may be different
 from the one below depending on the options you want included, but the
 important line to include is --with-fgdb=/usr/local/FileGDB_API. This is my
 configure line on my system: * ./configure --with-geos=yes
 --with-sqlite3 --with-python --with-spatialite
 --with-fgdb=/usr/local/FileGDB_API --with-postgres --with-odbc
 --with-libkml=yes --with-curl=yes
 --with-mrsid=/usr/local/MrSID_SDK/Raster_DSDK
 --with-mrsid_lidar=/usr/local/MrSID_SDK/Lidar_DSDK
 --with-openjpeg=/usr/include*

 The --with statements let the configuration script know what additional
 modules you want to be included in the compile. When you install packages,
 such as geos, from the repos the libraries are put in paths that ld (which
 is a utility that links libraries so that other applications are able to
 find them) knows about. When you compile by hand the general practice is to
 compile to /usr/local, which sometimes ld doesn't know about by default.
 You let ld know about additional paths by creating a configuration file in
 /etc/ld.so.conf.d/ that contains the path of your custom compiled
 libraries.

 To compile GDAL with the options you want, your line might look something
 like this:

 *./configure --with-geos=yes --with-sqlite3 --with-python
 --with-spatialite --with-fgdb=/usr/local/FileGDB_API --with-postgres
 --with-odbc *

 After configure runs, it will give you a summary that indicates what it
 was able to find. Check to make sure that there is a 'yes' beside the
 options you want. If there is a no beside something you want to include,
 you may need to scroll through

able to find. Check to make sure that there is a 'yes' beside the options
you want. If there is a no beside something you want to include, you may
need to scroll through the output and find the error to see what went wrong.


5. Now you can run make and make install. *sudo make*. When that finishes,
run *sudo make install*.

6. One more step: you need to let ld know about the gdal libraries. Since
we didn't specify a different path, the configure line above puts them in
/usr/local/lib by default. I let ld know about the libraries by adding a
local.conf file to /etc/ld.so.conf.d/. *sudo echo /usr/local/lib 
/etc/ld.so.conf.d/local.conf*

7. Run ldconfig again: *sudo ldconfig*

*
*

You should be able to open geodatabases in QGIS or any other GIS
application that uses GDAL now. I expanded on notes that I took while doing
the install, but I didn't have my linux laptop with me while writing this.
Let me know if anything doesn't work or if clarification is needed.

Re: [Qgis-user] create a tiff multy layer

[Eric Goddard]

You can accomplish this with gdal. On QGIS 1.8.0, go to the Raster
menu - Miscellaneous -Merge. Select all of your input files and
check the layer stack option. The output will be a new tif image with
each of your previously independent images as a band which you can
then assign to the RGB guns by pulling up the layer properties and
clicking the symbology tab.
