.tfw Data Calibration

Postby FredenFromSweden » Sat Jun 24, 2006 10:47 pm

Does anyone know how to use the data from a .tfw file that comes with a geoTIFF file to calibrate a map with PathAway?

Here are the parameters in the file;

A': pixel size in the x direction in map units
D': rotation about y axis, always 0
B': rotation about x axis, always 0
E': pixel size in the y direction in map units
C': x coordinate of the center of the upper left pixel
F': y coordinate of the center of the upper left pixel

thanks for any help!

You must use TouraTechQV.

If you have a few maps only use "Import map" or "drag and drop".

If you have got a huge amount you can import it through CD (simulated or real CD).

Burn .tfw files to CD with images (probably .tif).
Use TTQV -> “File-Import new map CDROM automatically”

And you can export it to PathAway.

It is possible to export it in batch by PWConvertMap.
But if you use CD it needs some additional steps :-)
