REGRID: A GENERALIZED GRID-TO-GRID TRANSFORMATION PROCEDURE

In recent years geographical information has been collected and digitized for many different regions in the United States. The most common representation of such data has been through the use of grid systems in which the region is broken up into a large number of cells. Since there is a significant number of different geographical coordinate systems and map projections in existence, digitized information exists over the country in a number of different grid systems. In order to merge and analyze spatially distributed data digitized in these different systems, a transformation from one grid to another must be performed. This report describes a generalized technique for grid-to-grid transformation in which a variety of data representations are allowed. Although the procedure was developed for problems in environmental and regional analysis, it is also applicable to non-geographic problems such as heat transfer mesh problems.
