[mapserver-users] Is mode=tile always epsg:3857?

[Michael Smith]

Rich,

 

Looking at mode=tile, yes, it sets it to spherical Mercator

I'm trying to generate vector tiles in a non epsg:3857 (web mercator) projection but it looks to me like mapserver is treating it as 3857 despite passing a srs. 

 

My request generated by OpenLayers at the full map extent is:

  /cgi-bin/mapserv?map=mvt.map&SRS=EPSG:3738&mode=tile&tile=0+0+0&layers=ownership&map.imagetype=mvt

 

My extents are: 1622000 639000 2308000 1284700

 

My mapserver log looks like:

[Sat Oct 24 11:10:58 2020].947687 msTileSetParams(): tile_metatile_level = 0
[Sat Oct 24 11:10:58 2020].947690 msTileSetExtent(): gmaps coords (x: 0, y: 0, z: 0)
[Sat Oct 24 11:10:58 2020].947692 msTileSetExtent(): gmaps metacoords (x: 0, y: 0, z: 0)
[Sat Oct 24 11:10:58 2020].947695 msTileSetExtent(): base image size (256 x 256)
[Sat Oct 24 11:10:58 2020].947697 msTileSetExtent(): buffered image size (256 x 256)
[Sat Oct 24 11:10:58 2020].947700 msTileSetExtent (-19959236.823047, -19959236.823047) (19959236.823047, 19959236.823047)
 

There's obviously something that I'm not getting...
