I am having issues with outputting ers raster file from gdal_grid. I
import a csv as shape, then grid it and output as ers. The Y coords are
all negative as it is in fact a section I simply grid as a 2D raster.
Although the shape file plots as I expect it, the ers is flipped
upside-down, and hung at the lowest Y value. Please note, if I use GS7BG
it works fine.
How do I get an ERS output that matches the shape file/data points?
I have created a simple example... however, I am new to GDAL, and this
is my first post, so please let me know if there is anything else I
should provide.
Thanks
Ron
These are the commands:
711 ogr2ogr -f "ESRI Shapefile" xc_zc.shp new.csv -oo
X_POSSIBLE_NAMES=xc -oo Y_POSSIBLE_NAMES=zc
712 gdal_grid -zfield Value -a linear:radius=5 xc_zc.shp -of ERS
xc_zc.ers
here is the content of the data
xc,zc,Value
1.25,-0.625,5

I have attached a jpg of my output (not sure whether the mailing list
allows attachments...)
