ugh..
I have been attempting to create an interpolated (IDW) raster from CSV,
to no avail all I get is either a totally black tiff or white tiff
here is the command line I have been trying
gdal_grid -a invdist:power=2.0:smoothing=1.0 -outsize 800 600 -ot
Float64 -l temps temps.vrt temps.tiff
and the CSV http://metar.michiganwxsystem.net/temps.csv
here is the vrt
<OGRVRTDataSource>
<OGRVRTLayer name="temps">
<SrcDataSource>/var/www/html/metar/temps.csv</SrcDataSource>
<GeometryType>wkbPoint</GeometryType>
<GeometryField encoding="PointFromColumns" x="Longitude" y="Latitude"/>
<LayerSRS>WGS84</LayerSRS>
</OGRVRTLayer>
</OGRVRTDataSource>
anybody gather where I'm going wrong ??
