Hi,
I am inquiring to know if there is an appropriate place to put a CEP50
(circular error probability 50%) measurement in a geotiff.
Thanks in advance,
Isaac

Hi All,
I have a tiff in which each pixel is a single byte (0-255) which references
a colortable. Each element of the colortable has 4 values (RGBA).
I would like to convert my black color (entry 1 in the color table
(0,0,0,255)) to be transparent (new colortable entry is (0,0,0,0))
Another
file in step 3 smaller in size
specifically to match the theoretical size of 60MB?
Thanks again,
Isaac

rgb2pct.py does not work on tifs with indexed colormaps -- I have already
tried this.
I am already using COMPRESS=LZW on the mosiac.

I mispoke.
rgb2pct.py will work but only on RGB images -- no colortables. When I use
it on a RGBA image, the transparency is no longer preservered.

To be clear, suppose I want to make the red bow in the image below as a
tiff file with transparency. But instead of using RGBA, can tiff create it
with indexed color?

Hi All,
I have a raster image of 2200x1000 pixels. I know three bits of
information about the geoposition of the raster:
1. The upper left hand corner's lat and long of the image.
2. The pixel size in meters. The pixels are square
3. The rotation of the image relative to the upper left hand
Hi all,
I've spent some time today working with the SetGeoTransform function today
and want to mention that the documentation doesn't seem quite clear and
maybe even a bit misleading.
In here,

Im not sure I understood your original message. In any case, I have it
working now though I used a different GDAL
Do you guys know when 3.2 will be supported? How do I build from 3.2
currently using the patches you mentioned -- are there instructions
anywhere?
Thanks in advance,
Isaac
