[Qgis-user] scraping svg from web site to load into QGIS
I was able to download the entire svg (grey polygons)that was contained within this web-based map application. But, I cannot figure out a way to load this as a layer in QGIS. Whenever I try to open it, it just gives me an error. I suspect because it has no CRS information?

Re: [Qgis-user] Slooooow spatial joins
I can appreciate that but it forces to create another layer/file I think. I really don't want to have to re-import my entire table back into postgis just to get this one column.

[Qgis-user] Slooooow spatial joins
I have tried using MMQGIS plugin, refFunctions geomwith function and the aggregate function. I am using 3.18 QGIS Despite having spatial indexes on both tables, when I try to use any of these operations to assign the value of a field in the polygon layer to one in the point layer, it goes very slow. Like, ridiculously slow and of no value. And, I only have 600 records in the points layer and just a few thousand records in the polygon layer. What can I do to speed this up? -- Sincerely, Ryan ___ 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
[Qgis-user] Model Designer - Updating Field in Place
Hello, I have created a new Model in Model Designer and I'm using a Point Layer as Input and a Field Calculator that calls a custom function. I would like the output/result of the field calculator to update an existing field in the attribute table. I cannot get this to work. I can only get it to output a new temporary scratch table.

[Qgis-user] snapping polygons together
I am making a grid layer and I want to copy/move some of them to 'lock' into adjacent ones perfectly. Trying to avoid messing with the vertex editor. zooming in close to the edges never gets it exact. I don't want to drag the corner vertices and snap, I just want to move the whole polygon and snap it to the edge of another. Maybe I'm missing something. -- Sincerely, Ryan ___ 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

Re: [Qgis-user] Blurry XYZ tile layers
Wow! These vector tiles are awesome. The Qwant Map is great. Has all the driveways here in the States, and pretty darn accurate!

[Qgis-user] Virtual layer with an http/https import source
I was very much helped by Mr Duivenvoorde in the previous thread about virtual layers. I was able to get his solution to work! Thanks!! When you add a new virtual layer to QGIS, it allows you to import a source (in my case a csv). Is there a way to have this source be hosted in the cloud on a public URL so that all we have to do is upload a new file every day and all QGIS users that want access can just point their virtual layer to that site/file? -- *Ryan Peel* ___ 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
[Qgis-user] Move polyline objects by set distance
I have several polyline objects (hundreds) that I want to move on the map by a short distance (3ft to the N, S, E, or W) in a cardinal type direction. I see the Move Objects tool in QGIS 3 but that doesn't allow me to specify a distance. I have used the Offset tool in the QAD plugin to create parallel lines but that is very tedious and creates a copy of the object. Is there a way to select a bunch of objects and just move them in one direction or another by x # of feet?

Re: [Qgis-user] Polygon from 4 points
Extending this thought a little. Is there a way to create a WMS service
from this so that the WMS reads a csv file, automatically creates the
polygons using the expression that Toto recommended, so that it (on the
fly) creates the polygons from adding the WMS to a map so I can share with
my co-workers so that we are all using the updated data (rather than having
to share a shp file).
Long question, hoping for maybe an easy solution.
