.ALG File

The alg file extension is related to EP Mapper. Instead of a disk-to-disk based processing used by older technology products (even if they hide it behind a GUI), ER Mapper combines processing steps into an algorithm, and uses this to display the processed imagery.

This means files of any size, with any level of complexity, can be processed in real time. No more waiting, and no more temporary disk files. And when it's time to save the processed image, all that needs to be saved is the algorithm file, a small (normally 6K or less) ASCII text file.

Files with alg file extension are mainly related to ER Mapper program and used for its algorithm data files.

How to open:

Use ERDAS ER Mapper to open *.alg algorithm data files.

How to convert:

ER Mapper may be able to export *.alg files to other formats.
