| Summary: | 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. |
