Steve,
*Your suggestions worked.* I am now able to use my MapServer to serve a
shapefile to my World Wind client.
1. I changed the projection in my map file to 900913.
Initially I got a new error that, "msProcessProjection(): no options found
in ‘init’ file". I checked my epsg file in /usr/share/proj/epsg. It did not
contain a definition for 900913. I found a definition online. I added it to
the end of my epsg file and it cleared up the error.
<900913> +proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0
+y_0=0 +k=1.0 +units=m +nadgrids=@null +no_defs
2. Updated my wms_onlineresource field to replace that incorrect trailing ?
with a &.
Once those changes were made, it worked.
I have one follow on question, *how did you know that epsg:900913 should be
used from looking at the shapefile?* Is there a dictionary somewhere that
says Google Mercator=900913?
Here is my corrected map file per Steve's direction. Thank you for the help.
