Re: [Qgis-user] QGIS 2.14.1 does not find internal GPSQ

[Laurence Béchet]

Hi Eggerer,

I personally use DNRGPS to download data from my GPS save them in 
Shapefiles (and .gpx), before using them in qGIS. I have not tested with 
tablets, nor investigated much, but DNRGPS is said to be able to be run 
on memory stick if I do well understand:
"DNRGPS is a self-contained program which means it can be run from 
anywhere – your hard drive, a thumb drive, a network location. Simply 
unzip the DNRGPS folder and place in the location of your choice."


Maybe this would help you?
Cheers
Laurence

[QGIS-it-user] QGIS 2.14.3 campi virtuali e layer virtuali

[Totò]

Salve a tutti;
in uno shapefile ho creato, tramite il calcolatore di campi, un campo
virtuale che dipende da altri campi;
successivamente ho creato un virtual_layer in cui ho richiamato il campo
virtuale e ottengo un errore sulla view, errore localizzato nel campo
virtuale.

Chiedo se è normale oppure è un bug da segnalare.

questo è il virtual layer:
SELECT LINE, MakeLine(MakePointZ(CAST(X_1 AS float),CAST(zz_ex AS
float),32633)) AS geom 
FROM profilo_shp 
GROUP BY LINE

zz_ex è il campo virtuale che è una funzione di altri campi.

questo è l'errore:
Query execution error on CREATE TEMP VIEW _tview AS SELECT LINE,
MakeLine(MakePointZ(CAST(X_1 AS float),CAST(zz_ex AS float),32633)) AS geom
FROM profilo_shp GROUP BY LINE: 1 - no such column: zz_ex

saluti

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

[Michael Treglia]

Thanks all for the quick feedback! I'll give these things a try and will
report back. And for what it's worth, same issue with using both
openFileGDB and ESRI FileGDB drivers.
Cheers,

Hi Michael,

That's probably GDAL's openFileGDB driver and it's interaction with Esri's
Coded Domains, there's an open ticket at
https://trac.osgeo.org/gdal/ticket/5741

It doesn't sound like there was any resolution to it based on other threads
(
http://osgeo-org.1560.x6.nabble.com/gdal-dev-OGR-How-to-access-Coded-Value-Domains-in-File-Geodatabases-td5180262.html

access without some amount of work.

Not exactly an answer, but more info, cheers,

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!
Eric

[Qgis-user] Lookup Tables in File GDB?

[Michael Treglia]

Hi All,

I'm trying to work with a planimetric dataset available here:
https://data.cityofnewyork.us/Transportation/NYC-Planimetrics/wt4d-p43d,
which is available in a FileGDB format.

When I load the layers from the gdb in QGIS, some fields are field with
numeric values (e.g., entries in the PARK layer, for the FEATURE_CODE
column are integers). However, when I load the gdb in Arc, FEATURE_CODE is
filled with string entries (e.g,  'Park Boundary'). Thus, it seems like
ESRI uses a lookup table or something on this. Does anybody have experience
in dealing with this type of issue? Is there a good way to deal with this
via QGIS or OGR? (I'm ultimately wanting to import the data to PostGIS,
where the same issue is occurring, using org2ogr)

Thanks!
Mike

Non credo ci sia un problema di privacy per gli utenti di QGIS.
La vedo piuttosot come la dimostrazione che QGIS e' uno strumento
maturo, e ormai uno standard di mercato.
Ovvero: volevamo conquistare l'universo con i GIS liberi, e ci stiamo
riuscendo.

[Qgis-user] What is the name for "pyspatialite" package in fedora 19?

[童言]

My qgis misses pyspatialite module when it runs in Fedora 19. But I can't find 
"pyspatialite" package in the URL http://rpm.pbone.net/, so what is the name 
for "pyspatialite" package in fedora 19?

Re: [Qgis-user] Project relation - sci. notation

[Nicolas Cadieux]

Hi,
My guess is that the value where imported from a csv with no field type 
value.  Therefore, text values could have been imported as float values 
in the shape file.  What is the field type for both your files?

[Qgis-user] Project relation - sci. notation

[Chris Berens]

Hi there,

I have a layer of homes (roofs) and a list of residents who are linked to a
home by the roof number.  The homes are attributed via a re-blocking
exercise running 1-31 and A-J, eg. 18G is a block. Within each block there
may be up to 100 homes, eg. 18G-47.

So under Project Properties I set up a relation called 'households' and
using the Identify Features tool I can view the members of a household by
clicking on the roof. Works great, most of the time.

When I click on an E block roof (eg 18E-23) it returns all 291 XXE-XX
residents on the list.  It appears to me as if the relation is reading the
values as scientific notation numeric values instead of the declared text
status in both files.

I have an *Attribute table* in the a *Composer* window in the same *project*
that references the same relation perfectly, ie it only returns the
residents particular to eg 18E23.  So is the *Identify Features* tool using
a different select rule set or parameters?

I have tried to search for a previous thread on this topic without success.
The pain would appear to be for me alone, but can anyone suggest a way of
defining a relation to avoid this?

FWIW I'm using 2.14.3-64bit on Win7, this behaviour is true for sqlite and
shp formats.

Thank you for your attention,
Chris
