[Qgis-user] Date on which a GeoPackage layer was last saved

2020-11-27 Thread Iain
So I have had a bit of a disaster and a project I was working on has mysteriously disappeared. It is not a huge issue as I was using the project to edit some vector files (of a railway network). The vector layers are in a GeoPackage. However I have two layers with similar names and I am not

Re: [Qgis-user] Does QGIS3 freezes more often than QGIS2 ?

2020-11-27 Thread David Addy
I used to get a lot of similar freezes on QGIS 3. It was traced to the browser window being full of files that I never would use for QGIS. So if your browser window within QGIS has a lot of irrelevant stuff, you could try clicking on each one and selecting, "Hide from Browser" option. This should

[Qgis-user] Layer copy different sizes

2020-11-27 Thread L.W.
Hi, I made a copy of a layer from gpkg to postgresql. I saved the symbol properties to a symbol and 2nd copied the symbology from old to new layer. But the 2nd new layer's lines are much bigger than the old ones. Text, formulares are the same and correct. What did I missed? Regards

Hi, I did suggest it indeed. Ideally, it would go in the QGIS core every time they ask for a z factor. (Like under shading in the layer style). I will probably play around with it just to learn who to make a plugin but if you want to put it in your plugin, go ahead. Nicolas Cadieux

Hi, For now, probably just a box where you entre y and x and an select an ellipsoid. Ideally, you could just pick a raster and the latitude at the centre of the file and the project ellipsoid would be selected. I have the python formula for Proj as I use it in my python script. I just

I have a Lat Lon Tools plugin, Field Calculator function that generates the UTM zone. Nicolas, you just reminded me that you had suggested this to me earlier as a plugin. Something like that would be easy to add, but I'm not sure it fits within Lat Lon Tools which captures different coordinates,

Hi Nicolas, It is just a simple formula for calculating the "z-factor" for a given latitude. What would that look like in a plugin? Where would it go? What would it do or show? Last week I had a similar idea for a plugin that could tell you which UTM zone to pick for your current canvas. I

Hi Ryan, I think you could create a python QgsVectorDataProvider for your data and setup a QGIS server for hosting a wms. https://www.itopen.it/qgis-vector-data-provider-python/ But I would probably just go for a simple script that converts the csv file into a polygon dataset (gpkg, shp,
