Abstract
A method is disclosed of mapping raster data input of a source data set to a destination data set, wherein the source and destination data sets have different resolutions. Initially, a resolution ratio is determined between the source data set and the destination data set. The horizontal component of the source data set is converted to the resolution of the destination data set by copying select discrete groups of the source data to form a desired number of discrete groups of the destination data. A select number of vertical, or raster, rows of the horizontally converted data set are copied to form a required number of rows, thereby completing the destination data set. Look-up tables are provided to efficiently convert the horizontal component of the source data set. An apparatus for mapping raster data input includes a computation mechanism for determining the resolution ratio, and mechanisms for converting the horizontal and vertical components of the source data set into the destination data set. Additionally, a look-up table generator is provided.
