Change coordinate system to EPSG:28992

[beunderf]

Hi,

With our customer, most data is in EPSG:28992. The user guide gives me the following information:

If you have lots of coordinates in another coordinate system than WGS-84 it might be efficient to run GeoAnalytics in another coordinate system. You then need to provide a background map in that coordinate system, either a tile service or a simple vector file.

Can someone give me a more hands-on explanation on how 'run GeoAnalytics' in another coordinate system?

Thanks,

Frank

Hi Frank,

This probably calls for a longer post, but here's the short version.

• QGA default base map is in web mercator EPSG 3857
• Default feature layers should be in WGS84 EPSG 4326
  
• QGA can handle background and feature layers in other projections using base map "Empty" meter or degrees
• If a custom projection, then all layers should follow the same projection.
• No reprojection takes place on the client.

So for instance, using your CRS EPSG:28992, it's a meter based CRS:

• Switch to base map Empty meters
• Load a background WMS in CRS EPSG:28992
• Load coordinates from an excel file with EPSG:28992
• Connect to WFS, use EPSG:28992

Fyi, when importing data through the connector in other projections, the connector automatically converts to WGS 84, EPSG:4326.

Thanks,

Patric
