Hi,

I haven’t heard any feedback yet. Test data seems to be still available and I believe that the issue is real. It seems that nobody has bothered to create a ticket yet https://github.com/mapserver/mapserver/issues.

Hi,



My colleague has suffered from the same issue. Here is a link to a directory with a mapfile and corresponding datasets (OSM data as GeoPackage and Natural earth populated places as shapefile) http://193.167.189.71/temppi/

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

I will be away for a while so I cannot do that right now. 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. WMS request with FORMAT set to image/png

    - I got a png image with 50k points drawn)



mapserv?map=D:\home\site\wwwroot\100k_3857_node.map&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&layers=nodes&width=800&height=600&srs=epsg:3857&STYLES=&bbox=-8979930,4769116,-8362889,5173075&FORMAT=image/png



2. WMS request with application/x-protobuf

    - got the same result like the following:


       nodesIdName(€ x



mapserv?map=D:\home\site\wwwroot\100k_3857_node.map&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&layers=nodes&width=800&height=600&srs=epsg:3857&STYLES=&bbox=-8979930,4769116,-8362889,5173075&FORMAT=application/x-protobuf<http://xxx.com/cgi-bin/mapserv?map=D:\home\site\wwwroot\100k_3857_node.map&SERVICE=WMS&VERSION=1.1.1&REQUEST=GetMap&layers=nodes&width=800&height=600&srs=epsg:3857&STYLES=&bbox=-8979930,4769116,-8362889,5173075&FORMAT=application/x-protobuf>
