Thanks to GDAL developers and William Kyngesburye's help (http://
www.kyngchaos.com/software:frameworks), i could build a standalone
GUI for gdal_translate and gdalinfo for Macintosh PPC Mac OS X Tiger
(10.4)
It is a drag & drop application for converting a JPEG map into an IGN
Geoportail , DATUM=RGF93, PROJ=GEOPORTALFXX ECW map. Reverse
conversion ECW to JPEG is also possible.
The only requirement is to have a script file containing the
coordinates of the upper and lower corner of the map, and that this
script be in the same directory as the JPEG map file.
I would like to share this software (in a dmg file) for free by
posting on my website or any place. ERMapper license for libecwj2 is
extremely complex and i do not understand what is allowed and what is
not. Do you think that this would be legal?
More details on the software:
There are 3 applications:
1/
Jpeg2ECW_geoRef.app which contains gdal_translate, gdalinfo and the
4 libraries libgdal.1.dylib, libNCSCnet.0.dylib,libNCSEcw.
0.dylib,libNCSUtil.0.dylib
and a script running gdal_translate $1 $1.ecw
Another script file containing the coordinates of the upper and lower
corners of the map,
2/
ECW2JPEG.app which contains gdal_translate, and the 4 libraries
libgdal.1.dylib, libNCSCnet.0.dylib,libNCSEcw.0.dylib,libNCSUtil.0.dylib
and a script running gdal_translate $1 $1.JPEG
3/
GDAL_Info.app which contains gdalinfo, and the 4 libraries libgdal.
1.dylib, libNCSCnet.0.dylib,libNCSEcw.0.dylib,libNCSUtil.0.dylib
and a script running gdalinfo $1
gdal_translate and gdalinfo are the standard command line binaries
These drag & drop Mac OS X Application have been created thanks to
Open source Platypus developer tool by Sveinbjorn Thordarson
This is a very clever and easy to use tool.
Regards,
philippe
