FAQ
GRC to DDS Conversion
What are GRC files?
GRC is the classified grid format of Vertical Mapper, a spatial analysis add-on originally created by Northwood Geoscience in Canada and later acquired by MapInfo. A file of this type is a map made of equal cells, and each cell carries a category rather than a measurement, for example a land use class, a soil type, or a signal strength range. The category names and colors are stored with the map, so it can be displayed immediately. Its numeric counterpart, the .grd file, stores smoothly varying values such as elevation. The GRC format is widely used for mobile network planning, where coverage predictions around cell towers are saved as classified grids, and it is also used in mapping, environmental analysis, and land management.
What are DDS files?
DDS (DirectDraw Surface) is an image file format that usually contains texture data, cubic environment maps or other type of data compressed using the S3TC (S3 Texture Compression) algorithm. The DDS format was first associated with Microsoft's DirectX 7.0 and later on with DirectDraw, a tool for accelerating the rendering of graphics in various applications. DDS is a container file and can be decompressed using a graphics processing unit (GPU).
