Re: [UMN_MAPSERVER-USERS] Map files for dummies?

Dave -   Your EXTENT is in China, so if your shapefile is in Texas it won't show up.  Your Y-coordinate (longitude) values should be negative numbers in the Western Hemisphere, and should be reversed so the minimum value (more negative) comes first.  I expect ogrinfo is really reporting negative numbers - if it's not, then your data are in error.        - Ed   Ed McNierney President and Chief Mapmaker TopoZone.com / Maps a la carte, Inc. 73 Princeton Street, Suite 305 North Chelmsford, MA  01863 Phone: +1 (978) 251-4242 Fax: +1 (978) 251-1396 [EMAIL PROTECTED] From: UMN MapServer Users List [mailto:[EMAIL PROTECTED] On Behalf Of Dave Nuttall Sent: Friday, March 24, 2006 2:09 PM To: MAPSERVER-USERS@LISTS.UMN.EDU Subject: [UMN_MAPSERVER-USERS] Map files for dummies? I have an instance of Mapserver 4.8.1 running on CentOS with Apache 2.20, PHP 5.1.2 and Mapscript running as a DSO.   I can make/display maps where I use the canned tutorials.  But I’m failing to create map displays when I substitute shapefiles that are of local interest.   The shapefiles in question are apparently valid, since I can read them without any problems using “ogrinfo –al shapefile.shp”.   I extract the decimal dimensions and create my own *.map file, but all I ever get is the layer for pseudo-credits.   If someone could tweak my map file (which follows), it would be a valuable learning experience for me.   TIA.
