Abstract

Abstract: Raster intermediate layer is fundamental and reusable raster layer for terrain analysis created by the DEM, DSM, vector data, which is obtained through a series of raster calculation. The scale adaptability of raster intermediate layer is studied. The range, scale, resolution, analysis are defined. The principle of range, scale, resolution are determined. Particularly, the paper takes the experiment of scale adaptability of the tangent, curvature raster intermediate layer aiming at the analysis scale, and puts forward the adaptive algorithm and analysis scale. The result shows that raster intermediate layer of terrain foundation factors created from this solution meets the need of numerical precision and morphology precision for terrain analysis.

Key words: raster intermediate layer, scale adaptability, terrain analysis, numerical precision, morphology precision
