Concept information

Granule Data Format > ASCII Grid

PREFERRED TERM

ASCII Grid  

DEFINITION

  • Esri ASCII Grid files are raster files containing elevation data, and each elevation sample in the file is a point in a single FME raster feature. Esri ASCII Grid is a very simple format. It has a very short header that precedes the raster data. This header provides the location and size of the raster to follow. The raster is written as a series of rows, which contain one ASCII integer or floating point value per column in the raster. The first element of the raster corresponds to the upper left-hand corner of the raster. For each raster, there is only a single feature returned, since this feature will contain the entire raster.
