Layers don't show up

Tue Feb 15 14:21:56 EST 2005

Wokar,

Two problems:

1. A file ending in .e00 is not a shapefile, it's an ESRI export format.    I don't think Mapserver will read those.  Search the MapServer email archive on how to convert e00 files to shapefiles.

2. You need to set your SHAPEPATH to have a leading "/" to indicate it's an absolute path:    
        SHAPEPATH "/var/www/temp"

  Subject: [UMN_MAPSERVER-USERS] Layers don't show up

  Hi,

  I have made a map file.  My layers are still not showing up??  I have changed my SHAPEPATH, i also tried to put my data in different folders but it still didn't work.  I have named my CLASSES and they still are not showing up on the le gend. 

  http://132.205.108.60

  If I try to access my map by writing http://132.205.108.60/cgi-bin/mapserv?map=/var/www/cgi-bin/ogr.map&mode=map&layer=mylandcover 

  it gives me the following errors:

  msDrawMap(): Image handling error. Failed to draw layer named 'mylandcover'. 
  msSHPOpenFile(): Unable to access file. (/var/www/cgi-bin/nhtm93s3) 
  msSHPOpenFile(): Unable to access file. (/var/www/cgi-bin/nhtm93s3) 

  When I try this :http://132.205.108.60/cgi-bin/mapserv?map=ogr.map&mode=map&layer=myroads

  msDrawMap(): Image handling error. Failed to draw layer named 'myroads'. 
  msSHPOpenFile(): Unable to access file. (/var/www/cgi-bin/rtf100k) 
  msSHPOpenFile(): Unable to access file. (/var/www/cgi-bin/rtf100k) 

  The rtf100k and the other file both have an e00 extension. Is there a way to check if these files are corrupted??  They open up in otepad though. I'm working in linux

  I tried putting all my data to var/www/temp but when i change my shapepath to this then int the above errors it says :

  /var/www/cgi-bin/var/www/temp/rtf100k

  why is that?why does it goes automatically to cgi-bin and then  to var/www/temp/rtf100k.

  Thank You all for your help. It is greatly appreciated.
