[mapserver-users] ogr csv layer in mapserver

[Murat Beyhan]

Dear all,

I used gdal 1.7.2 and mapserver 5.2.1

I try to draw layer which data csv file as follows

filename : kyh_sta_ogr.csv

"ID","STA_ID","Latitude","Longitude"
1,0104,37.02403,35.80947
2,0118,37.02100,35.19100
.
.
.


then I use ogr for reading data from that file as follows and map file
also here



LAYER
  NAME "kyh_vrt_ogr"
       CONNECTIONTYPE OGR
       CONNECTION '<OGRVRTDataSource>
        <OGRVRTLayer name="kyh_sta_ogr">
        <SrcDataSource>kyh_sta_ogr.csv</SrcDataSource>
        <GeometryType>wkbPoint</GeometryType>
        <LayerSRS>WGS84</LayerSRS>
        <GeometryField encoding="PointFromColumns" x="Longitude"
y="Latitude"/>
    </OGRVRTLayer>
</OGRVRTDataSource>' 
    DATA kyh_sta_ogr
    STATUS default
    TYPE POINT
  CLASS
    NAME "kyh"
    SYMBOL "cpoint"
    SIZE 1
    COLOR 0 0 0
  END
END  

Please let me inform what is wrong in my code and why always trouble to
draw ogr layer in mapserver.
mapserver gives following error message

msDrawMap(): Image handling error. Failed to draw layer named
'kyh_vrt_ogr'. msOGRFileOpen(): OGR error. Open failed for OGR
connection in layer `kyh_vrt_ogr'. Failed to open datasource
`kyh_sta_ogr.csv'.
  


but command 
ogrinfo -ro -al kyh.vrt 
as follows:

ogrinfo -ro -al kyh.vrt
INFO: Open of `kyh.vrt'                           
      using driver `VRT' successful.
