Retouching a satellite photography

Post by inca » Thu Aug 16, 2007 5:52 pm

Hi,

1) I have a GEOTIFF image (I have already retouch it in a graphic program) and I want to tranform it for obtain a ".bgl" file.
What is the procedure for that ?

2) Is it possible to reverse a processus: to obtain a graphic picture from an existing bgl file for a retouch in a graphic program ?

Your GeoTiff should have position information in it. Now you can use a simple script as shown below to "compile" it into a BGL file using FSX Resampler. The script file should have a name that ends in .inf (dot inf). I use Geotiff.inf.

My simple process is to put the .inf file in the same folder as the Resample program and also put the TIF file in that same folder. Change the .inf SourceFile to the file name for your TIF file. The DestBaseFileName will be the BGL name. I do not know how to make BGL into a TIF for more retouching.

[Source]
Type = GeoTIFF
SourceDir = "."
SourceFile = "ontario.tif"
Layer = Imagery
Variation = Day
NullValue = 255,255,255
Channel_BlendMask = 3

[Destination]
DestDir = "."
DestBaseFileName = "ontario.tif"
DestFileType = BGL
LOD = auto
