TerraConv is a freeware program for converting Terragen terrain files into image file format readable by image editing programs, and image files back to terrain files. Supports 16 bit color depth, so you will not lose any altitude resolution in the conversion process.

TerraConv supports the following file formats:   (R = Read, W = write)

Ext File type: formatR/W
.TER Terragen Terrains - R/W
(Tagged Image File Format)
8 bit grayscale R
16 bit grayscale R/W
32 bit HDR grayscale R/W
24 bit RGB color R
48 bit RGB color R
(Portable Grayscale Map)
8 bit binary R
16 bit binary R/W

Only non-compressed TIFF files are supported. When the file is read, it is converted into grayscale. When writing a TIFF file, 16 bit grayscale or 32 bit HDR (floating point) grayscale mode is used. When writing PGM file, 16 bit binary or ASCII mode can be selected.

TerraConv can handle terrains of size up to 8193 × 8193.
Terrain scaling data from .ter file is stored into a data file and can be restored after loading a TIFF/PGM file.
Scaling data from GeoTIFF file is automatically used (assuming the coordinates are stored in degrees and altitude in metres).
Supports drag and drop. Can be run from command line and .bat files, too.

See some example images created with help of TerraConv.

TerraConv works on Windows 95/98/2000/NT4/XP operating system. To install TerraConv, just unzip the files into any directory. You can then start the program by typing "tconv" on DOS command prompt, or by clicking on tconv.exe at Windows Explorer. Optionally, you can create a shortcut on your Windows desktop.

The ZIP package below contains the program file (TerraConv.exe) and a document file (TerraConv.txt).
