Hello list I need some help with de Virtual Spatial
Data I have this ovf and mapfile definition: <OGRVRTDataSource> <OGRVRTLayer
name=xy> <SrcDataSource>ODBC:@access</SrcDataSource>
<SrcSQL>SELECT * FROM XY</SrcSQL> <GeometryField
encoding='PointFromColumns' x='Long' y='Lat'/>
<GeometryType>wkbPoint</GeometryType> <LayerSRS>WGS84</LayerSRS> </OGRVRTLayer> </OGRVRTDataSource> LAYER CONNECTIONTYPE
OGR CONNECTION
"compress.ovf" DATA xy METADATA
"wms_srs" "4326"
"wms_title" "Compress" END NAME
"Compress" PROJECTION "init=epsg:4326" END SIZEUNITS PIXELS STATUS ON TOLERANCE 0 TOLERANCEUNITS
PIXELS TYPE POINT DUMP FALSE UNITS METERS CLASS NAME

I test ovf file with ogrinfo and it is OK like with shp2img, but when I insert this url into Internet Explorer: http://127.0.0.1/fcgi-bin/mapserv.exe/?mode=map&map=map.map&LAYERS=Compress I receive this message: writeLog(): Unable to access file. /tmp/gmap.log msDrawMap(): Image handling error.

Hi,
Did you try to run the Chameleon mapfile with shp2img? That will give you a more helpful error message.

I have solved it. The problem was that I had created a User DSN and a System DSN with a same name. When erasing them and creating only a System DSN the problem was solved.

You say that shp2img works for you but the application does not. The only thing I can think of is to make sure that you are using a System DSN.
