Re: [Qgis-user] QGIS through conda on Linux
So at this point your environment should be active - type qgis in the terminal and it should start. I ignore the ICD warning.

Mamba is something hidden in the background, for you it will pretend to be Conda. Conda is the original project, mamba is a faster, compatible alternative. Miniforge is something that comes with mamba "as conda" and automatically uses the big "conda-forge" repository where lots of software and libraries are available, packaged by the community. You can use the command lines from https://github.com/conda-forge/miniforge?tab=readme-ov-file#install After installation I recommend: $ conda config --set auto_activate_base false Otherwise every terminal/shell session will run using a conda environment instead of your standard system environment. Once installed, you can use the "create" line from other previous mail to install a QGIS environment. Then "conda activate qgis_3.34" to activate it in a terminal session, "qgis" in that same terminal to launch that QGIS and just close the terminal or enter "conda deactivate" to deactivate it again.

Re: [Qgis-user] QGIS for safe organization use.
Greetings from the South of Canada. So I'm a user and not a programmer by any stretch. The open source license for QGIS covers the Software. Your data is your data and no one else's unless you physically share it. It's not any less safe than Arcpro. The data it builds is compatible with ESRI products (it can build and edit ESRI file Based Geodatabases (which I'm guessing may be a requirement)). It's my daily driverwell - my only driver for Desktop GIS (I say that and PostGIS will make you feel things deep down in your soul). Anyway - I know that's a short answer but - Enjoy your QGIS'ing. Make Data. Enjoy. Randy On 5/23/23 12:09, Simon via QGIS-User wrote: Hello, I work at the Department of National Defense for the Canadian government and had some questions regarding QGIS.

After, I plan to create a layer that will show the location of these buildings on a map. Now, a large portion of the information regarding the buildings and their locations is confidential, and so I'm wondering if the geodatabase and layer that I plan to create will be safe and protected, or if other users will have access to them since QGIS is free and open source? At first, I was planning to work with ArcGIS Pro but I'm currently waiting for a license. When or if it comes through, I'll stick with ArcGIS but for now QGIS seems to be the best alternative.

I've got a Lenovo Laptop with an integrated Nvidia Quadro P2000. If you do anything involving 3D the window is black in 3.22 and 3.26.

Once you start building a layout add your map frame. Make sure it's selected and to the right you should see the item properties panel for the frame.

Re: [Qgis-user] 3.20.1 fails on Linux Mint
So I just did an upgrade on Ubuntu (Pop-os Technically) and if you pop a terminal open and do *sudo qgis* it's runs - which makes me think one of those bits with the file (<-technical term) aren't set correctly.

Re: [Qgis-user] Identify Results customization?
On the attribute window you can organize data and turn off fields - but they still appear using the identify window. Try this: * Right click on your layer * Go to properties * Go to Forms * Set the widget type for the field you want to hide to "hidden" and it won't show up with identify results.but it does still show up in the attribute windowHeh. (I wasn't expecting that but I've learned something). So I'm guessing it a combination of hiding the field using organize columns button and Setting with widget type to "hidden".

[Qgis-user] Fwd: Georeferencer Plugin Help - QGIS
Good afternoon QGIS People I received a question on RMSE errors in georeferencer and after talking to Ethan about it I realized I have no clue what I'm talking about. How would we go about calculating an RMSE for a rectified image in QGIS? I've cc'd ethan on this so he can chime in also. Thanks Randy Forwarded Message Subject:Georeferencer Plugin Help - QGIS Date: Fri, 2 Oct 2020 15:27:13 + From: Ethan Cissell To: i...@northrivergeographic.com Hi Randal, I have a question about the usage and outputs of the Georeferencer Plugin in QGIS, and thought, given your expertise, you might be able to directly help, or point me in the right direction. I am a Ph.D. candidate in Ecology and Evolution at Florida State University applying spatial techniques to study the dynamics of benthic cyanobacterial mats on coral reefs. This past summer, I photographically tracked individual cyanobacterial mats in which I had placed plastic stakes as ground control points for later image rectification. I am trying to essentially create image stacks, so that I can parameterize a generalized additive mixed effects model that accounts for the inherent spatial autocorrelation and includes a parameter with occupation at the previous time-point explicitly included to hopefully model the population dynamics of this system. Thus, a quantitative understanding of the error in my alignment is absolutely critical to the downstream conclusions (especially for informing my resampling to larger grid size to account for error in my alignments). I am using QGIS for obtaining all raw data from these photos (scaling, rectification, classification, resampling), but I am stuck at the rectification step. I am using the “Georeferencer” plugin to accomplish my alignments, but I have received mixed advice on how to interpret the residuals output on the GCP table in the Georeferencer window (screenshot below). The documentation for this plugin seems to indicate that the far right column (Residual) is actually a per GCP RMS error. Can you tell me how to interpret these errors/how to obtain a total RMSE error for the image alignment (i.e. not just per GCP error, but total error for each image)? I have been told to sum all of the values from the residuals column and take the square root of that raw summation. Is this correct? Many thanks in advance. I apologize for the lengthy email, but I wanted to establish the motivations for this project so that you would have more context for the goals of the alignment. Any and all help here is greatly appreciated.

Re: [Qgis-user] Road Labels
One thing you could do is take the roads you downloaded for Michigan and
clip them against the county boundary. You should be able to get the
county boundary from the Michican open data site or the census. If you
add both the roads and county boundary to your QGIS session I would
1. select your county
2. Open the processing toolbox
3. search for clip
4. Be sure to clip the roads with the selected county
5. Save out your new roads layer to a shapefile (or geopackage) and work
with the smaller dataset.
Yell if you have any problems - good luck!

Hello Helpful Members;
I am a fairly new user (about 3-4 months now). I have been using the
online tutorials, the training manual and anything I can understand.
BACKGROUND
I am a parking planner so I create maps of my study area, which is
usually an entire city, in various US states. For example, right now
I am working on Rockford, Michigan, USA. I know it is a small area,
but it is one in which we have already done the study and I am trying
to recreate everything we did for them (my GIS person no longer works
with us, so I am learning).
WHAT I NEED TO DO
I need to be able to add a layer containing street names for my study
area. This layer needs to have an attribute table I can manipulate to
get only the streets (labels) within my study area. I do not want the
point bubbles (ex: Target, Leo's Coney Island, etc.) that point out
restaurants and places of interest that I seem unable to get rid of
when I use google roads (xyz:
https://mt1.google.com/vt/lyrs=h={x}={y}={z}
<https://mt1.google.com/vt/lyrs=h=%7bx%7d=%7by%7d=%7bz%7d> ).
WHAT I HAVE TRIED
I am unable to manipulate data in open street maps. I have tried to
download the roads vector file from the State of Michigan. However,
this file is so huge (as it contains every road in the state) it keeps
crashing every time I try to manipulate it. I have been able to
select just the roads in the area I want using an expression, but it
crashes when I try to select one of the roads to remove it from the
study area (stragglers I do not want to show after using the select
area tool). I have also tried to select all the records I do not need
in an effort to delete them in the hopes of making the file smaller.
Again, it crashes.
MY QUESTION
Can someone please give me a link to a tutorial that will show me
where and how to get just the road names for any US city (as I need
them). Or provide me with directions to do what I need? I have been
trying to figure this out for over 2 months now and just can’t seem to
find what I need.
As my computer constantly crashed using QGIS after the new Windows
updates, we have installed new hardware in hopes to keep it from crashing.
Dell Computer
Currently have 16 gig memory (increased from 8)
2 gig AMD Radian R5 Video card (newly installed)
Core I3 processor
Using QGIS 3.10.9 (3.14 won’t load)
Sorry for the long email. Please let me know if you require more info.
Thank you for your kind attention.

Re: [Qgis-user] Live Mapping with QGIS on Toughbook
It does on Linux. It's always worked well for me after I stumble through setting up things. I should write it downbut haven't. I'm wondering though can you connect Bluetooth to GPSD - In other words can I connect my Linux Laptop to my phones GPS and still use GPSD? I've not tried mostly hadn't had the time or the "wanderlust" to work through the process. I assume you can. There's not much you can do these days with a linux workstation.

And maybe qgis allowing 2274-but-no-ellipsoid is a bug too. -- --- Randal Hale rjh...@northrivergeographic.com https://www.northrivergeographic.com (423)653-3611 ___ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user

Now I'm getting a ballpark transformation message if I move data from 2274 to 4326 (for instance I'm moving points to a GPX Format).BUT - if I set the Ellipsoid to be GRS 1980 (which it is for that projection) - no warning.

Which now has me thinking MAYBE I should set the ellipsoid. EXCEPT my area measurements always come out a bit larger than expected. Which **IS** expected! :D An ellipsoidal area will almost always result in a larger area vs a cartesian area calculation, because it's calculating the area over a curved surface rather than a flat surface. (same applies to length measurements). Generally my advice is to use ellipsoidal area/length calculations, unless the specific constraints and specifications of a particular task or discipline dictate otherwise. If in doubt, I'd: 1. compare the two area calculation results. The identify tool "derived attributes" section handily shows BOTH cartesian and ellipsoidal areas/lengths, if you've setup your project to use an ellipsoid. If the results are relatively similar (e.g. say within 0.1% of each other), then ask yourself whether it makes any difference practically which of them you use. Chances are the accuracy of your input datasets will be a bigger factor here then the area calculation method used, and you may be chasing false accuracy by reporting areas to that many significant figures anyway! Or, in other cases, the actual purpose of the calculations you're making aren't even required to a degree of accuracy to warrant being affected by the choice! (e.g. if you're calculating species density, then it's an inherent estimate only and the practical outcome of choosing between cartesian/ellipsoidal calculations is nill). I'm really starting to wonder if this started back at 3 (in my head) and I've continued down the wrong path since then. Maybe it was a bug or something in the beginning and I never adjusted based on everything getting fixed. Maybe. I really don't have a good answer. 2. if you've checked and the input datasets ARE sufficiently accurate that the choice matters, then push the choice back to your customer. Ask them which method is suitable for the results they're after. Get the answer in writing and your method is justified! 3. keep in mind that even ellipsoidal measurements are an estimation. The earth isn't an ellipsoid! Local variations in elevation are likely to have a much more significant impact on large scale calculations vs the cartesian/ellipsoidal choice. Hope that helps! Yes - it helps. I'm getting a lot of questions from people getting "ballpark transform" messages which led to the last little bit of testing, head scratching, and "Hey I can be completely wrong on what I'm doing".

Re: [Qgis-user] shapefiles
Yeah - that's a layer order issue. Just drag that line above your ortho over in the layers panel. Select the layer and drag it up. You can move stuff around pretty easily in that panel. If you ever dump a shapefile out of some custom Forestry software it could (like something to COGO boundaries or do cruises) it can become a projection issue easily. BUT - you're on the right track!

Are your layers completely misaligned, like not overlapping at all? Or are they overlapping but with just a few (hundred) meters shift? An easy trick is adding the world layer and see which of your layers appears at the expected spot. You can do this by typing "world" in the coordinate bar beneath the map. Good luck!

Re: [Qgis-user] wishing for accurate lattitude/longitude from a cell phone
eet off. I imported
the data trying both EPSG 4326 and 4269.
I'm now convinced that the problem is due to (1) my Google Pixel 3 cellphone, (2) the app I'm
using ("Latitude Longitude" published by gps-coordinates), and especially (3) my
less-than-steady hands. I capture coordinates by standing at spot, waiting for the blue dot to
settle, and then touching the blue dot. Often I don't touch the screen at exactly the right place.
I tried another app ("GPS Coordinates" published by Financept) which is better in that
it allows me to zoom in, but I'm still not always getting it right.
I'm thinking now that I need specialized equipment. That is what I want to
ask you. Can you recommend some inexpensive device that will allow me to
simply press a button to record accurately the coordinates of the point where
I'm standing? Keep in mind that this is a community project with no funding.
I live on Social Security and a university pension, but I'm willing to pay
something in the range of $50 or a bit more. Do you know of anything at such a
modest price, or would I have to pay much more? Or perhaps you know of better
software for my Android Pixel 3 phone.
Thanks in advance for any advice you might offer.

Re: [Qgis-user] question about live vs linked connections
Good question. So There is a plugin called offline editing. You can connect to a postgis database - sync it to be offline - edit it and sync it back to the original table. I've not used it in production for a bit but I did a quick test against a local database and it worked fine. I'd give that a test and see if that would work for you.

Can one create a linked table in QGIS such that it links to a postgres db table, but if remote it can still be opened, used and edited? Edits would get saved back to the postgres db when not remote and likewise, changes from the postgres db could be refreshed back to the linked table when connected. When working with ODBC connected tables in MapInfo one has this option (live or linked).

[Qgis-user] Meeting in October 2019 in the Southeast US
Good Morning/Afternoon QGIS Listserve - and sorry for the duplication/spam as I've sent this out on several other listserves and many of you are way outside of the SE United States. I'm hopefully going to hold a QGIS centric meeting in the Southeastern US in October 2019. Right now I'm trying to piece together an interested group of people and hold this around the Chattanooga TN area (which could be Huntsville, Chattanooga, Knoxville, Asheville, etc). It will probably be a 1 day meeting but depending on interest we could go more. I've held meetings (with the help of a lot of great people) in the past [1] centered around FOSS4G software and they've had quite a turnout with topics ranging from SAGA, LIDAR, QGIS, and PostGIS. There is a OSGEO Listserv covering the SE US [2] and I'm preparing to pepper the list with information and put up a central location for information. I'm open to suggestions for a location. I'm hoping to nail down a date and location shortly so if you are so inclined join the listserve below and we can discuss. I'm open to sponsors and whatever else we might need. Usually the biggest expense for these meetings is food and snacks. Depending on interest we may need more than that. Anyway - hopefully those of us in the Southeast US can get together and talk about QGIS.

You can also go the GRASS Route for LAS files. You get GRASS with an install of QGIS by default.

Start QGIS and go to Settings -> User Profiles -> New Profiles. QGIS may not freeze with a new one.

Re: [Qgis-user] PIN # LookUp Help?
I did a quick glance at their website - I assume you've downloaded the data. If you have the data downloaded and open in QGIS you can also use the Select Features By Value Tool (its on the attributes toolbar and you can also tap F3 on your keyboard) and enter the pin number in the appropriate field and it should autocomplete. From there you can zoom, flash, etc the parcel. I think someone also mentioned the "locate tool" in the bottom left corner of QGIS.

After I upgraded to 3.4.2 I still had problems with everything running very slowly. (See my post below - QGIS 3.4.2 still very slow to work in Windows 10 by David Addy) Now on 3.4.3 the same issues seem to be continuing, with the odd crash added in for good measure. Opening QGIS on Windows 10 always takes over half a minute before anything happens apart from the outline box of the QGIS window full of blank space. Once a project finally loads up any random operation gets the "QGIS not responding" message. I can scan a map without any problem, moving it around works fine, as does zooming in and out. But if I want to amend the contents of the attribute table or change a style in the Layer Properties I get “QGIS is not responding”. After a long delay it may respond correctly. This can result in further issues because I may try pressing buttons to get a response. After long frustration it might decide to crash. I use the stand -alone version of 64 bit Windows package, which loads with QT 5.11.2. I run a 16 gb computer with Intel i7 processor. It seems to make no difference whether I have my Kaspersky Security Suite turned on or off. Frustratingly, some other users apparently experience no problems with Windows on QGIS. Ubuntu users are ecstatic – they work lovely. If you are on Windows 10 and are still having these sort of issues on QGIS 3.4.3 it would be very helpful if you could add a note to this thread so we can gauge the numbers involved. Useful also if you can note whether you use the standalone package, 64 or 32 bit, and the QT package installed. Thanks very much.

Re: [Qgis-user] QGIS Functionality and Training
I do training - just not on this specifically. I'd have to sit and think about it how to work this in. I'll answer in line and maybe someone has a better answer (possibly Kurt Menke) 1. I would think GRASS would be more appropriate than QGIS. A lot of the tools in grass are exposed in QGIS - so maybe we could do basin delineation using those tools but within QGIS. 2. I'm not sure - but we can figure it out. QGIS can export to about anything - so it's possible. Shapefiles make the world go around - that and CSV text files. 3. Yes. 4. Without looking I believe so. Possibly would have to be one in GRASS or with one of the exposed tools from GRASS in QGIS. 5. 6. 7. Yes.

With the newer Garmin units you can copy a GPX file to the unit (like a USB drive). I replaced DNR GPS with QGIS (we just create a GPX file and copy it). * We generate all the Plots and digitize the stand information using QGIS - when I started working with them, they were a arcivew shop.

Re: [Qgis-user] QGIS and ESRI's ArcMAp
Good Morning (Greetings from TN) It's a really mixed bag as far as capabilities. I say that - I haven't used ArcGIS now for a bit except at ones client's office. The big thing you'll notice is it's a different workflow (not necessarily one being more right over another). So if you try some workflow you're used to in ArcGIS you might get a bit frustrated - but I get frustrated now with ArcGIS because of my workflows in QGIS. * In general all the extensions you're used to are already included. So things like the spatial analyst toolset is there already. * Probably the 3D environment in Pro is better (but I've never opened pro) - but QGIS is gaining momentum. * I find the community here is more vibrant - you can send emails on Saturday at noon to the listserve and get an answer. * I think QGIS is more flexible - but probably 8 years ago I would have argued ArcGIS was. I enjoy this software more now. * I think the cartography tools are equal and possibly better than ArcGIS. * Everyone here is more receptive to suggestions. You can file a bug report and talk to a person (and not get a error). Give it a shot and start playing with it. Do a small project. Style it all up - make a PDF. Hopefully you'll like it - possibly love it. (look here -> this might help although it refers to an older version of QGIS - it's still a great read - https://gisunchained.wordpress.com/2016/01/28/qgis-features-i-long-for-while-using-arcgis/ ) Randy On 06/29/2018 07:59 AM, Crosby, Scott wrote: Good morning, Are there tools and/or capabilities unique to QGIS that are not available in ArcMap?

Re: [Qgis-user] QGIS 3 Plugins missing
Be sure to click on "ALL" in the plugin manager. That will give you more than 11. If you are looking at installed then you will have 10 or 11 installed. The plugins have to be fixed for python3 - so your favorite plugin might not be there yet - but it should get there fairly soon. Good Luck!

Randy Hi, maybe I misunderstood your needs but I don't see the issue. The authcfg is just an ID that the QGIS authentication manager uses to retrieve the credentials from the QGIS user authentication DB. If I get your point, what I suggest you is that you create your project (the one that needs to be distributed) and configure your layers with a custom authcfg (you can use up to 7 digits or letters to name it) and just tell the users to create an entry in their authentication DB (using the authentication manager in their QGIS instance) with same authcfg that you have chosen and with their credentials.

Re: [Qgis-user] LiDAR Data in QGIS
I'm dealing with a different issue here in Tennessee - We have the original files except they are locked in zlas (ESRI Proprietary Format) BUT - I can get it out of zlas so I can have fun with the LAS files. Good news is - LAS was a thing in 2003 (https://www.asprs.org/committee-general/laser-las-file-format-exchange-activities.html) so you might be able to get those OR at least a CSV file. You might have to go back to the vendor. They probably have them but might take some work to pry the files out of them. 2003 might be a life time ago for many. Good luck though! and take a look at GRASS and PDAL. I feed the LIDAR data into GRASS and pull the returns out or reprocess it. I'm not that great at doing it but learning.

Re: [Qgis-user] LiDAR Data in QGIS
I've only been watching this thread when I remember - so My apologies. If I go back to the original thread - if these are in ADF I believe that's ESRI's GRID Format. Which means they are what they are and you can't do much with them. They have only the last return (or if I remember correctly returns classed 2,8, etc). If you have zlas, las, or laz - I would suggest GRASS for processing: https:// grasswiki.osgeo.org/wiki/LIDAR If you don't have any of the las/laz formats - you might want to do some research and see if they were delivered with the LIDAR dataset you have or if they weren't request them. They may be sitting somewhere on a shelf/forgotten folder on a server. You can do a lot more with the original LIDAR files like pull tree heights or possibly rebuild the surface (be it dsm/dtm/dem etc). Randy -- Randal Hale North River Geographic Systems.

[Qgis-user] Question on Area in QGIS 2.18.13
I have a question - this didn't seem to be an issue until 2.18.12 QGIS. I'm currently on 2.18.13 Ubuntu 17.04. I could be missing something. I have a forestry client and they were preparing to do some aerial spraying. So I outlined the area to be sprayed and generated acres. Generally I set my project properties to feet (for units) and square feet (for area) and the ellipsoid set to none/planimetric. My data is stored in WGS84 in postgis. I pulled it out into a shapefile and eventually stored it in geopackage while trying to track down my issue. Dropbox link to the data: https://www.dropbox.com/sh/8w1spcxu5by7z70/AACilL5kOeOC7tzX4WCEkOdka?dl=0 I set the CRS to EPSG:2274 - the data is in wgs84. If I run acres with project properties set to feet, square feet, and none/planimetric and using the Field Calculator I get: 372.82 acres. This is wrong. If I run acres with project properties set to feet, square feet, and wgs84 as the ellipsoid I get 307.41 acres which appears to be right. If I run acres using the virtual layer abilities: /select sum(st_area(st_transform(geometry,2274))/43560) from spray/ I get 306.04 acres which may be right. I didn't notice this until 2.18.12 - I updated to 2.18.13 and it is still acting "odd" - I didn't notice in 2.18.11 but I'm not sure if I ran any area calculations in 2.18.11. I have also noticed that if I switch from wgs84 (feet, square feet, none for ellipsoid in the project properties) and then switch to EPSG:2274 the ellipsoid changes to grs1980(iugg 1980).. which having the ellipsoid at GRS80 may have been covering for my area calculations and making them "about right". Anyway thoughts? Ideas? Am I doing something wrong?

[Qgis-user] Snapping: Move Features vs Node Tool
A question. In an attempt to help a client I'm doing some data cleanup - which is good. I spend too much time talking and not enough doing. I need to snap points to the endpoints of lines. If I set snapping up and use the move features tool the point doesn't snap to the line. If I move the point using the node tool the point snaps to the line. I've been looking for an option or something to change. I'm not seeing one. Is this expected behavior? To me it would make more sense for both tools to snap data - but I may be missing something. If I add data, the data snaps as I would expect it. The good people I'm helping immediately started moving data and it didn't snap - and I've instructed them to use the node tool to make the edits.

Re: [Qgis-user] spatialjoin
steps, though it produces a lot of temporary files cluttering the project. A better way for all those repetitive tasks, is to use the graphical modeller, to create a workflow which only has to be triggered once new points come in, and the resulting file can be saved as new a file e.g. with the current date in the name, so you have kind of an archive and do not overwrite previous files (and destroy your work in case something goes wrong). So I can imagine a model with input layer A (new points in WGS84 without attributes) and a parcel layer B (in whatever projection). reproject layer A and C will be created as an intermediate step. Next input layer is the latest result layer D, reprojected and with attributes. Merge layer C and D -> E. Now delete all columns which are from layer B (from the last spatial join. Unfortunately, you can only delete one field at a time in the modeller, so you'll will have to add the command several times in a row to the model) -> Fn Do the spatial join of Fn with B. The last result G will now hold all points with the corresponding parcel info plus additional fields you might have added to the points. G will be the input D in the next run with fresh points. So, do not add new points to the already existing collection of points in WGS84 (it is never save to edit layers without backup), but just import them as a new input set and then run the model with the parcel layer and the last result layer. The modeller is not as intuitive as it should be, but it can save you a lot of time once you managed to set up a model. Maybe I was completely wrong analysing the problem, but maybe someone else has the problem that fits to my solution ;) Cheers Bernd Am 21.12.2016, 14:07 Uhr, schrieb Randal Hale <rjh...@northrivergeographic.com <mailto:rjh...@northrivergeographic.com>>: 2 things: 1.

Re: [Qgis-user] Splitting Spatialite layers
You're hitting a bug that exists in QGIS 2.16 and 2.18 - They are
working on a resolution.
See Below:

On 12/11/2016 08:39 PM, custard wrote:
Hi All,
As a mostly shape/tab file user, I've been attempting to experiment
with spatialite dbs a bit recently, and am starting to get a bit more
used to them. I'm hitting a problem with splitting objects though, and
wondered if this annoyance counted as a bug?
If I have a spatialite layer and split an object, that's fine. But
when I save the layer I get a "Could not commit changes to layer
LayerName" banner. If I press "Show more" then I get something like this:
_
Could not commit changes to layer layername
Errors: SUCCESS: 1 geometries were changed.
SUCCESS: 1 attribute value(s) changed.
ERROR: 4 feature(s) not added.
Provider errors:
SQLite error: UNIQUE constraint failed: LayerName.pkuid
SQL: INSERT INTO
"layername"("geometry","pkuid","Code","Lith","Description","Quality","code1","lith1","description1","quality1")
VALUES (ST_Multi(GeomFromWKB(?, 28351)),?,?,?,?,?,?,?,?,?)
I'm not populaing the pkuid data, so I think QGIS is auto filling this.
I think that what's happening is that when QGIS splits the feature
both new parts have the same pkuid number. Certainly if I go in
manually and change the field I can save without errors.
If QGIS is auto filling this column, ought it not be handling the
splitting case too?
Thoughts?

Let me see if I can break it on my end. It's opening for me and I just opened it with a random win protocol I just picked. Lemme do some digging - I'm not entirely sure why yours isn't opening.

Re: [Qgis-user] Advanced Digitizing Panel
OK - figured it out. I think I was floating back to some long forgotten

Advanced Digitizing panel isn't enabled UNTIL I start adding a feature.
I was attempting to add the feature by using the Advanced Digitizing Panel.
Sorry for the noise on the list - but thanks for the help.

Re: [Qgis-user] Count points overlaying a raster layer
I would convert your raster to vector. Assuming you are on 2.18 (which is what I am currently using) - open your processing toolbox. At the top of QGIS click on Processing -> Toolbox. 1. In your toolbox go to GDAL/OGR -> Conversion -> Polygonize raster to Vector. Once you change that to a vector file then go to the next step. 2. In your toolbox go to QGIS geoalgorithms -> Vector Analysis Tools -> Count points in polygons. That should add a field to your new polygon shapefile with the number of points in that polygon. Good Luck. On 11/28/2016 09:37 PM, K Imran M wrote: Dear all, I apologize if this has been asnwered before.

In the processing Toolbox there is a tool called Variable Distance Buffer. If you add a field to your data giving each type a width (field called bufferwidth and it is 10, 20, 30 , 40 meters for each type) - you can use that tool to automatically buffer each fault accordingly.

In map composer I can set my scale (Feet) to 1:7920 which is 1 inch to 660 Feet. * I can display a scale bar. * I can display scale text (1:7920) Can I display "1 inch to 660 Feet" through use of an expression? I've been manually typing it in and sometimes I'll change map scale and forget to change the typed scale.

Re: [Qgis-user] Clipping a Raster with a Mask Layer - update - possible bug
So I've got an update on this. If I run this with the command line (gdal 2.1): gdalwarp -cutline acid_forest_buffer.shp low_east.tif output.tif /Processing input file low_east.tif.// //Using internal nodata values (e.g. -3.40282e+38) for image low_east.tif.// //Warning 1: Self-intersection at or near point 2309.5402184630693 1121.2793755624425// //ERROR 1: Cutline is not valid after transformation/ I had one community member confirm the clip works in 2.14.1. I think ultimately this is a gdal version problem - sort of. If I look at the shapefile in QGIS I get an error using the topology tools looking for overlaps. I seem to have 2 multipolygons in this data. I clean those up and the tool runs as expected. Is there something with gdal 2.1 that chokes with a multipolygon in running this type of clip against a raster?

Re: [Qgis-user] is there a way to install a running well version of QGis in Xenial 16.04??
Henri - sorry for the late reply back.
If you look under /etc/apt/sources.list.d - do you have a QGIS.list
file? Or something under /etc/apt/sources.list with a repository listing
for QGIS?
Yes - it is possible because I am sitting here running QGIS on Ubuntu 16.04.

And if I may add:
Even if the users are aware of the fact that ubuntugis-unstable
contains the current releases, it can be hard to impossible to
convince a GIS-ignorant system administrator that it is OK to
install “unstable” packages.
But this issue is not a QGIS issue I guess...

Not like it matters much in this case.
Re: [Qgis-user] Ubuntu updating instructions
I don't think it's necessarily ignorance - the word unstable means "no stable; not firm or firmly fixed; unsteady" [1]. At my old place of employment software that was in any way related to the work "unstable" would never get installed or tested. UbuntuGIS-unstable isn't unstable. BUT - it has that word associated with it. It is confusing for users. If we told the windows users to grab their installation files from a directory labeled *unstable* there would be much unhappiness.

Not like it matters much in this case. We have packages in qgis.org/debian/ against the plain versions of the distributions (debian and **ubuntu**) and in qgis/ubuntugis/ packages against newer dependencies from - and only from - ubuntugis-unstable. Looks like it's hard for people to accept that there are also ubuntu packages in a directory called debian and that probably makes them jump on the other because it has ubuntu in it's name. I was thinking about it last night (and I was up way to late) and it is a bit confusing for the casual user. They've installed Ubuntu (or mint/debian/xubuntu/etc) and they may not understand ubuntu is based off debian. So like you said - they see debian but want to use Ubuntu. They go to UbuntuGIS and they see the repositories for UbuntuGIS and the choice is unstable (and no one likes unstable software) and stable (which doesn't contain the newest software). So you end up going "Use Unstable because it's stable and current". Under my /etc/apt/sources.list.d directory I made a qgis.list file and put the following in there: debhttp://qgis.org/debian xenial main debhttp://ppa.launchpad.net/ubuntugis/ubuntugis-unstable/ubuntu xenial main Why? That are the packages not based on ubuntugis with the dependencies from ubuntugis. Do I have this wrong? I thought I had the repositories for the install correct based off the directions on qgis.org. Which I could completely have it wrong. With the above repos I'm getting QGIS 2.16.x and GDAL 2.1.x.
