MapInfo Workspace File: This file works as a workspace that organizes mapping layers and geospatial referencing information for raster images. It is associated with tools from LightPhase and ERDAS IMAGINE.

Functionality:
The first type is used in monitoring and presenting industrial process information. The second type helps manage workspace settings for mapping and image alignment.
