Hello Carlos,
my CSV-file ans VRT-file looks like your examples:
My CSV is
x-utm,y-utm,Wert
742226., 5374978., 0.00E+00
743422., 5375072., 0.00E+00
744620., 5375166., 0.00E+00
...
and my VTR is
<OGRVRTDataSource>
<OGRVRTLayer name="boden">
<SrcDataSource>/daten/csv/boden.csv</SrcDataSource>
<GeometryType>wkbPoint</GeometryType>
<GeometryField encoding="PointFromColumns" x="x-utm" y="y-utm"/>
</OGRVRTLayer>
</OGRVRTDataSource>
and as I wrote, ogr2ogr could read my vrt/csv data and transform it into
a shapefile..

Check that you have your CSV like this:
Lat,Lng,House
48.1,0.25,"My house"
49.2,1.1,"My girlfriend's house"
47.5,0.75,"My mother in law's house"
And that you have your VTR like this:
<OGRVRTDataSource>
<OGRVRTLayer name="neighborhood">
<SrcDataSource>[FILE]</SrcDataSource>
<GeometryType>wkbPoint</GeometryType>
<LayerSRS>[YOUR SRS]</LayerSRS>
<GeometryField encoding="PointFromColumns" x="Lng" y="Lat"/>
</OGRVRTLayer>
</OGRVRTDataSource>

*Subject:* [mapserver-users] VRT / CSV data sources are not displayed
in a layer
Hello List,
The following layer uses a CSV-file (together with a VRT-File (Virtual
Format) ) as datasource . When I try to visualize the layer, nothing
is shown (neither the data nor error messages; shp2img shows also nothing)
LAYER
NAME "boden"
DEBUG on
STATUS ON
TYPE POINT
# DATA "/daten/csv/boden/boden" # Datenquelle Shapefile
CONNECTION "/daten/csv/boden.vrt"
CONNECTIONTYPE OGR
PROJECTION
"init=epsg:25832"
END
METADATA
"WMS_TITLE" "test"
"WMS_SRS" "EPSG:25832"
"WMS_ABSTRACT" "test"
"WMS_FEATURE_INFO_MIME_TYPE" 'text/html'
END
CLASS
NAME "test"
STYLE
SYMBOL "circle"
SIZE 15 COLOR 90 90 90
END
END END
But if I transform the CSV/VRT-file into a Shapefile via ogr2ogr
ogr2ogr -s_srs EPSG:25832 -t_srs EPSG:25832 -f "ESRI Shapefile" boden
boden.vrt
the layer displays the data.
What is wrong with my VRT/CSV-datasource in the mapfile?
Thanks for any idea.
Best regards
Stefan
