Toward GIS-Based Modeling and Estimation of Flood Inundation Area
摘要
The chapter discusses a technique of river-type flood inundation modeling that is unavailable in contemporary desktop GIS software. Standard tools of desktop GISs can be used to implement the technique and to automate needed computations. The technique is based upon the raster algebra methodology and spatial proximity estimation. Reinterpolation can be applied to reduce artifacts in interpolated gridded map of the flood inundation water surface. Proposed technique can be applied to wide-area flood inundation mapping. It helps also to ensure flood inundation mapping for testing purposes or as an operative activity in the conditions of incomplete or inconsistent initial data.
