Hye,
I'm trying to create a 3D terrain model (export format : .obj/.fbx/.3ds or any other textured mesh format) from imagery raster (France, IGN) and elevation raster (France, IGN).
Inputs formats are :
1. For imagery
Multiple *.jp2 files with *.tab files associated (same file name)
A sample of .tab file :
!table
!version 300
!charset WindowsLatin1
Definition Table
File "01-2015-0830-6540-LA93-5M00-E100.jp2"
