Abstract

This study aims to analyze land-use change by a digitized-grid method, a simple technique that can be used for such
analysis. We describe a procedure for restructuring land-use data comprising polygonal “shape files” containing successive
(x, y) boundary points of plots for geographic land-use categories as grid-digitized data, and illustrate this method using data
from Thailand. The new data comprise a rectangular grid of geographical coordinates with land-use codes and plot identifiers
as fields in database tables indexed by the grid coordinates. Having such a database overcomes difficulties land-use
researchers face when querying, analyzing and forecasting land-use change
