[gdal-dev] Appropriate place to store CEP50 in Geotiff

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 ___ gdal-dev mailing list gdal-dev@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/gd

Re: [gdal-dev] Giventiff with colortable, how do i assign one of the colors to be an alpha channel

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? http://d241yswl6yg9sc.cloudfront.net/remove-background2/4.png Isaac On Wed, Jan 16, 2013 at 3:40 PM, Isaac Gerg wrote: > E

Re: [gdal-dev] Giventiff with colortable, how do i assign one of the colors to be an alpha channel

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. Isaac On Wed, Jan 16, 2013 at 3:17 PM, Even Rouault wrote: > Le mercredi 16 janvier 2013 20:58:51, Isaac Gerg a écrit : > > Even, >

Re: [gdal-dev] Giventiff with colortable, how do i assign one of the colors to be an alpha channel

rgb2pct.py does not work on tifs with indexed colormaps -- I have already tried this. I am already using COMPRESS=LZW on the mosiac. Isaac On Wed, Jan 16, 2013 at 3:17 PM, Even Rouault wrote: > can also try to gdal_translate -co COMPRESS=LZW on the mosaic, since > I'm not sure how efficient th

[gdal-dev] Giventiff with colortable, how do i assign one of the colors to be an alpha channel

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 w

[gdal-dev] Created a rotated (non-north) geotiff

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 corne

[gdal-dev] Improving the Documentation of Get/SetGeoTransform

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, http://www.gdal.org/classGDALDataset.html#f9593cc241e7d140f5f3c4798a43a668, the transform is mentioned a

[gdal-dev] GDAL for Python 3.2 on Windows 64bit

Hi Everyone, I am wondering if there is a build (beta or release) of GDAL for Python 3.2 on the Windows 64bit platform. I have been browsing around the ticket area of the website and there appears to have been code entered in to make GDAL compatible with python 3.2. However, I cannot find where
