Raster Formats AAIGrid: This format is the ASCII interchange format for Arc/Info Grid, and takes the form of an ASCII file. The Arc/Info ASCII Grid format is an elevation grid exchange format used by Arc/Info.
Limitations: If pixels being written are not square (the width and height of a pixel in georeferenced units differ) then DX and DY parameters will be output instead of CELLSIZE CEOS: There are three main levels of CEOS data. The first, known as CEOS Level 0 data, is the raw stream of data transmitted from the satellite and the formatted stream of satellite data. CEOS Level 1 data is mainly in the form of images that are derived from CEOS Level 0 data. The level of processing done on the data varies from the raw image, such as what the satellite "sees," to flatten out geocoded images. Further processing of these images, results in data types known as CEOS Level 2 data.
Limitations: reads only the image data, and does not capture any metadata, or georeferencing.only work with eight bit unsigned data. DTED: Digital Terrain Elevation Data is a uniform matrix of terrain elevation values which provides basic quantitative data for systems and applications that require terrain elevation, slope, and/or surface roughness information
Limitations: Supports creating new files, but the input data must be exactly formatted as a Level 0, 1 or 2 cell. ENVI: ENVI (the Environment for Visualizing Images) is a revolutionary image processing system. ENVI was designed to address the numerous and specific needs of those who regularly use satellite and aircraft remote sensing data. ENVI provides comprehensive data visualization and analysis for images of any size and any type—all from within an innovative and user-friendly environment
Limitations: Limited support for recognising MapInfo keywords with the coordinate system and georeferencing. In particular, UTM and State Plane should work. FAST: The "EOSAT Fast Format Rev. C" consists of one ASCII header file and one simple binary image file for each band
LAN: Erdas GIS files are used to store raster data (i.e. imagery, scanned maps).
HFA: The ERDAS Imagine Image format is the raster data format used with the ERDAS Imagine software product line. Typical imagery includes satellite data as well as land coverages.
