[gdal-dev] gdal_translate failing with Corner Coordinates for geotiff

[Jan Martin]

Hello all,

I am trying to create a geotiff from a .png (screenshot for testing), but
gdal_translate gets the corner coordinates wrong.

My steps:
Works with Chrome Browser only:
http://overlay-tiler.googlecode.com/svn/trunk/upload.html
with screenshot:
http://www.diy-streetview.com/data/geotiff/Neurott.png
and
Ampèrestraße 63225, Langen, Hessen, Germany

gives:

gdal_translate \
 -gcp 0 0 8.648622773788475 50.00162255942198 \
 -gcp 644 0 8.655532144210838 50.00162255942198 \
 -gcp 644 899 8.655532144210838 49.99542253867455 \
 Neurott.png out.png

gdal2tiles.py -s EPSG:4326 -z 16-19 out.png out

Entering the local file names:
gdal_translate \
 -gcp 0 0 8.648585222862266 50.001663936185025 \
 -gcp 644 0 8.65549459328463 50.001663936185025 \
 -gcp 644 899 8.65549459328463 49.995463920773624 \
 /home/me/geotiff/Neurott.png /home/me/geotiff/Neurott.tiff

seems to work, but

gdalinfo /home/me/geotiff/Neurott.tiff

shows that the Corner Coordinates are the pixel values, and not the lat/lon
coordinates:

Size is 644, 899
Coordinate System is `'
GCP Projection =

Band 1 Block=644x4 Type=Byte, ColorInterp=Red
Band 2 Block=644x4 Type=Byte, ColorInterp=Green
Band 3 Block=644x4 Type=Byte, ColorInterp=Blue

How to fix this?

I tried with
GDAL 1.11dev, released 2013/04/13
installed on ubuntu via sudo apt-get install gdal-bin
and
GDAL 1.10.1, released 2013/08/26
compiled locally on Ubuntu 64 bit, 12.04.3 precise.
Both get this wrong.

Any ideas?

Thanks,
Jan
