I’ll have a look at this too. My demo instance had a point player so it certainly should be working. Can you share your data (contact me off list if you’d like)? --Steve

However, I can do that probably early next week. If it helps, I just tried WMS request to generate both png and mvt and I got the similar result: 1.

I am able to generate mvt output for a line layer but is having problem with a point layer. The mvt output is kind of empty (just contains layer name and column names). I am getting correct geojson outputs for both layers using WFS. Here is the URL that I use to get MVT output: mapserv?map=D:\home\site\wwwroot\100k_3857_node.map&mode=tile&tilemode=gmap&tile=18+24+6&layers=nodes&map.imagetype=mvt Here is the map file: MAP EXTENT -9036156 4707746 -8243569 5174793 CONFIG "PROJ_LIB" "D:\proj\SHARE" NAME "TestMap" WEB METADATA "ows_enable_request" "*" END END PROJECTION "init=epsg:3857" END OUTPUTFORMAT NAME "mvt" DRIVER MVT FORMATOPTION "EDGE_BUFFER=20" END LAYER NAME "nodes" TYPE POINT STATUS DEFAULT CONNECTIONTYPE PLUGIN PLUGIN "msplugin_mssql2008.dll" CONNECTION "Connection to SQL Server Spatial" DATA "GeomCol from MyTable USING UNIQUE id USING SRID=3857" CLASS STYLE COLOR 0 0 0 END END PROJECTION "+init=epsg:3857" END METADATA "wfs_title" "WFS service for Nodes" "wfs_srs" "EPSG:3857 EPSG:4326" "wfs_abstract" "WFS service for Nodes" "wfs_enable_request" "*" "gml_include_items" "all" END END END With almost an identical map file and an url (layer name and table name differ), I am getting a good mvt output for my line layer. Any suggestions would be greatly appreciated.
