Re: [Qgis-user] Best Free high resolution DEM for Nepal

[Alexei Schwab via QGIS-User]

Hi Bibek, 

GPXZ (https://www.gpxz.io/) has good documentation of the best available free 
DEM for different countries and regions.

They use 30m Copernicus DEM for Nepal, you could also use 30m NASA SRTM as an 
alternative. 

Regards, 

Alexei

Re: [Qgis-user] geojson

[Alexei Schwab via QGIS-User]

Hi Manuel,

Can you give some more info about your data and how you are trying to use it? 
If you can share a link to a copy or sample of the data, even better.

>From your sample it looks like you're maybe trying to make a webmap - where 
>does QGIS fit in? Are you using the qgis2web plugin?

The more info you can share about your data and workflow the more likely it is 
someone will be able to help.

Regards,

Alexei

Re: [Qgis-user] geojson

[Alexei Schwab via QGIS-User]

Hi Manuel, 

You can change the position of the label in the layer label settings: 
https://docs.qgis.org/3.34/en/docs/user_manual/style_library/label_settings.html#placement-for-line-layers

Under the Placement tab > General settings section, you can change the text 
position from Above line to On line. 

You might want to add a buffer or backgroiund to the text to keep it legible 
over the line. 

Regards, 

Alexei

Re: [Qgis-user] Extracting colours from a vector file

[Alexei Schwab via QGIS-User]

Hi Grant,

Not sure if this is what you mean but if you want to get the colour of a 
feature's symbol you can use @symbol_color in the expression builder.

So adding a "colour" column to your attributes and using field calculator to 
set the expression to @symbol_color will give you the colour for each feature. 

It will give you a hex colour code. 

If you need the RGB values, you can use  the expression:

colour_part(@symbol_color, 'red'), colour_part(@symbol_color, 'green'), 
colour_part(@symbol_color, 'blue')

Regards,

Alexei

Re: [Qgis-user] What QGIS plugin development should I work on this year?

[Alexei Schwab via QGIS-User]

Mike, have you looked into Map Themes?
https://docs.qgis.org/3.22/en/docs/user_manual/introduction/general_tools.html#configuring-map-themes

Sounds like it might help with your problem.

[Qgis-user] Two 'Random Points in Polygons' tools?

[Alexei Schwab via QGIS-User]

Hi QGIS list,

In my install of QGIS 3.28.1 I have two tools in Vector > Research Tools menu: 
* Random Points in Polygons
* Random Points inside Polygons 

See screenshot here: https://imgur.com/a/FyuPc2p

To me they look very similar but I was wondering if anyone on the list could 
clarify if they do anything different?
