FAQ
ERS to DDS Conversion
What are ERS files?
ERS is the header file of the ER Mapper raster format, developed for the ER Mapper image processing software, now part of ERDAS. A dataset of this type consists of two files: a plain-text header with the .ers extension and a binary data file with the same base name and no extension. The header describes the data in a structured, readable form, including the number of lines, cells, and bands, the data type of the pixels, the cell size, the byte order, and the coordinate system. The data file stores the pixel values themselves, without compression. The format is used for satellite and aerial imagery, geophysical grids, and elevation models, particularly in mining, exploration, and remote sensing, and it is recognized by many mapping and geoscience programs.
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).
