I have a simple vector data (EPSG:2177) and I want to add a WMS server:

http://mapy.geoportal.gov.pl/wss/service/img/guest/ORTO/MapServer/WMSServer

I choose a EPSG:3857 CRS, and still I have a blank page when updating my map in qgis2web plugin (sometimes it works on Leaflet but i need it on OpenLayers 3).

Any clues what am I doing wrong?

Update:

When I open WMS with Qgis I see 8 available WMS (also EPSG:3857):

OpenLayers should be able to reproject the rasters client-side, though this is not recommended for a WMS (lots of client-side processing). As you asked in reply to @iant, you would be better off using a WMS which serves in EPSG:3857. Leaflet cannot reproject rasters, so you would need an EPS:3857 WMS for that to work.

Looking at the WMS GetCapabilities document indicates that the server can provide maps in 6 different projections:

        <SRS>EPSG:4326</SRS>
        <SRS>EPSG:2180</SRS>
        <SRS>EPSG:2176</SRS>
        <SRS>EPSG:2177</SRS>
        <SRS>EPSG:2178</SRS>
        <SRS>EPSG:2179</SRS>

But EPSG:3857 is not one of them so this will only work if OpenLayers 3 is set to reproject the rasters itself. I'm not sure if qgis2web can do this by default but you may be able to modify the code it generates based on this example.

  • When I open this WMS in Qgis I see 8 CRS available, I've added o printscreen to me question – Marcin Sep 27 '16 at 8:39
  • I only see 6 in QGis too – Ian Turton♦ Sep 27 '16 at 8:44
  • Probably there is an error in my Qgis app. Maybe you could guide me to some orthophotomap or good quality satellite map WMS in EPSG:3857 (I am working on Poland area)? – Marcin Sep 27 '16 at 8:58
