Hello All,
I made a shapefile from a raster layer using gdal_polygonize.py. My
input values are float, but my first attempt of gdal_poligonize.py has
truncated these to integer values.
Ok, so I read the description of the utility on
http://www.gdal.org/gdal_polygonize.html, which says:
"The utility is based on the GDALPolygonize() function.
> Note that currently the source pixel band values are read into a
signed 32bit integer buffer (Int32), so floating point or complex bands
will be implicitly truncated before processing..."
Anybody got a version that handles float data?
Also, the link to the source code doesn't work at
http://www.gdal.org/gdal__alg_8h.html#3f522a9035d3512b5d414fb4752671b1
Cheers,
Alan Steel
