FAQ
GIS to DDS Conversion
What are GIS files?
GIS is a raster file format used by version 7.x of the ERDAS image processing software, the predecessor of the ERDAS IMAGINE (.img) format. A file of this type holds a single layer of pixels, most often a thematic map in which every value is a class, such as a land cover type, rather than a measured brightness. It is closely related to the .lan format of the same software generation, which stores multi-band satellite imagery such as Landsat scenes. The file begins with a short header that identifies the format version and describes the image size, the pixel depth, and the map location of the grid. Class names and display colors are usually kept in an accompanying file. The format was also supported by other mapping systems, including Arc/Info and ArcView.
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).
