Is it possible to manipulate the pixel values of a GDAL VRT and, if so, how?
The original data must remain unchanged.
I have a dataset which might be a bit rotated so that there are no data
values on the edges. I use region growing to find that parts on the edge to
not touch no data values in the
Hi,
If you want a standard x and y, you will need to reproject using a
projected coordinate systems like (WGS84/UTM Zone 18). Then, you will
get a square pixel resolution that is in meters. If you use WGS84
Long-Lat, grids or pixels are almost square at the equator but become
more and more
How to convert Lat Long bounds to geotransform values for a particular zoom
in EPSG:4326
I can generated a raster with width, height and the geotransform values.
But for an Lat Long bounds at a particular zoom say highest 22, will the
xres and yres vary with location ?
Gane
Thanks for your timely response. Well the PDF was generated at the source
by different form such that I didn't face this problem, that new version of
the file worked for me.

Hello,
I use gdalwarp, gdal_translate with too many gcps.
Then command says:
"Argument list too long"
Is thare any way to add too many gcps as bulk?

Hello,
I use gdalwarp for georeferencing.
I run gdalwarp with many gcps, then warning says:
"There is a problem to invert the interpolation matrix"
I think some errors may exist in gcps, but I don't know how to find where
it is.
Are there any simple way to find errors in gcps?
