What is an .RRD file?
.RRD is Reduced Resolution Dataset File
GIS file created by geospatial processing programs such as ERDAS IMAGINE and ArcGIS Desktop; stores a reduced dataset from an original raster image using pyramid layers, which speed up the display of raster maps; often used for saving discrete zoom levels on a map.
RRD files are commonly generated from raster data in GeoTIFF .TIF files or JPEG 2000 .JP2 files.
