Open IMD File
The IMD filename extension is primarily associated with the image metadata format used by Geographic Information Systems (GIS) programs such as ArcGIS.
A Geographic Information System is a type of database that contains geographic data, usually combined with software tools to condition, process, manage, analyze and visualize that data.
More about ArcGIS
ArcGIS is geographic information system software with map creation, visualization, and analysis tools.
Some metadata for the raster graphics formats used to represent cartographic data in ArcGIS is stored in IMD files.
The IMD file used by ArcGIS contains raster metadata added to a mosaic dataset of a raster type used by the program.
The metadata stored in an IMD extension file typically includes georeferencing information, band wavelengths, acquisition data, etc.
This file format is classified as GIS.
