[mapserver-users] msShapefileOpen(): Unable to access file

Wed Jul 13 10:08:14 EDT 2011

Hi,

One remark: the "missing connection" error was a fault alarm (CONNECTION is not needed with TILEINDEX).  We got those lines into log file at least with Mapserver 5.2 series but it has been corrected later.  Version 6.0 does not produce those. I do not remember what was the situation with 5.4.x and 5.6.x.
Add DEBUG 5 into your layer, let's hope it will generate something useful into into Mapserver log.

Dave,

Strange, it should work.  I'm using mapserver v5.6.3, with a layer def of:

   LAYER # LINE
     NAME 'LINE'
     CONNECTIONTYPE OGR
     STATUS on
     TILEINDEX "G:\GeoData\1_250k\Alberta\AltaLIS\250k_west.shp"
     TYPE LINE
     PROJECTION
       'proj=tmerc'
       'ellps=GRS80'
       'lat_0=0.0'
       'lon_0=-117.0'
       'x_0=500000.0'
       'y_0=-5000000'
       'k=0.9996'
       'units=m'
       'nadgrids=@null'
       'no_defs'
     END
     INCLUDE "AltaLIS_250k_render_inc.map"
   END

and the content of the "location" attribute reported by ogrinfo is :

   LOCATION (String) = G:\GeoData\1_250k\Alberta\AltaLIS\82gpos.dgn

Try adding a PROJECTION object to your LAYER def.  And try using a full
path in the TILEINDEX.

Best Regards,
Brent Fraser
