[gdal-dev] problem: gdal_grid, output ers raster file

[Ron Palmer]

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
3.75,-0.625,5
6.25,-0.625,5
8.75,-0.625,5

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