GeoMedia Q&A

Question

Customer states they have hundreds of TIFF files that were either registered in the MicroStation based GIS Imaging products (I/RASC or ImageAnalyst) or had been converted to GeoTIFF.  They want to extract the registration as a world file (.tfw) for use in another application.

Answer

This is easily accomplished in batch mode using the Many/Raw File Converter in the ImageStation Raster Utilities (ISRU).  ISRU can be downloaded from https://download.hexagongeospatial.com/downloads/imagestation/imagestation-raster-utilities-5-2-800.

Here's the command line flags for mr_file:

Use the -g option

for %j in (*.tif) do start /b /wait mr_file -g %j %~nj.tfw

This will do a whole folder at one time.

This command didn't work for me. But a slight variation does. I just convert my TIFF to JPEG while generating a JPEG world file. The JPEG world file is exactly the same as the TIFF world file that I want but with a different file extension. All I have to do is rename the world file using a *.tfw extension instead of the *.jgw that is generated. The batch command I use is "for %j in (*.tif) do mr_file -C j %~nj.tif %~nj.jpg". This will generate the JPEG image file along with the world file.

Note that the listgeo command line utility from libgeotiff, which is mentioned on that page, is included with ISRU.
