![]() To compress data so it needs less disc space. This format is identical to that used by Esri and Idrisi software for versions 4 and earlier.Ī binary format with or without a header (at the end) that uses several strategies Start at bit 0 and may contain unused bits at the end of a row (if there are Significant bit, and a byte never shares pixels from two rows: each row must Separation between image rows (except in bit files) moreover, in bitįiles, bits of each byte are numbered (0 to 7) starting with the least Pixels are placed from left to right and from top to bottom, without any ![]() ![]() Uncompressed IMG: A binary format without a header in which.The data file can be stored in several formats, Instance, resolution changes, resampling by interpolation, Understanding the nature of the stored data in eachĬell involves differences in the treatment of different spatial operations (for Value (that is, the more frequent class in that cell, like in many Value for each cell (the case of radiance sensor imagery or traditional aerialĬameras), to a central cell value (the usual case for elevation in DEM), to a modal Metadata file, about if that kind of data refers to a global mean In any case, users can get information, in the Thematic maps (land cover classes, etc), etc. ![]() Imagery, aerial photographs, digital elevation models (DEM), raster Net of squares (called cells or pixels) into a rectangular space. Raster to be any spatial representation made by dividing the space into a ![]()
