[mapserver-users] Feature points not drawn by 5.7DEV drawmap.exe

[Anzel, Phil - Fort Collins, CO]

Happy New Year, All,

Appended below is a short map file containing two layers: points and grid lines. The projection used by the map as well as the two layers is "Web Mercator".

When drawn with "drawmap.exe" from MapServer 5.6.3, all points and grid lines are shown. Using "drawmap.exe" from 5.7-development, the points are not shown. 

The 5.7-development "drawmap.exe", with associated DLLs, was downloaded from http://vbkto.dyndns.org/sdk/ on 12/15/2010. I'm using the "release-1600-gdal-mapserver.zip" file created for VS2010/Win32. The same point omission occurs if I use the "mapObj" from mapscript_csharp.dll, load the map file, and execute a "Draw" to generate an output byte array.

Is there an error in this map file? Is the difference an artifact of changes planned for 6.0, and if so, where might I find relevant documentation?

Thanks,

- Phil Anzel  (Web Soil Survey developer for USDA/NRCS)
