Influence of georeference for saturated excess overland flow modelling using 3D volumetric soft geo-objects

摘要: Existing 2D data structures are often insufficient for analysing the dynamism of saturation excess overland flow (SEOF) within a basin. Moreover, all stream networks and soil surface in GIS must be preserved appropriate projection plane fitting techniques known as georeferencing. Inclusion 3D volumetric structure current soft geo-objects simulation model would offer substantial effort towards representing SEOF dynamically basin by visualising saturated volume. This research attempts to visualise influence georeference system coverage total volume generated from process using VSG structure. The is driven Green-Ampt methods Topographic Wetness Index (TWI). VSGs analysed focusing on spatial object preservation conformal-based Malaysian Rectified Skew Orthomorphic (MRSO) equidistant-based Cassini-Soldner under existing geodetic Revised Triangulation 1948 (MRT48) newly implemented Geocentric Datum Malaysia (GDM2000) datum. simulated result visualises deformation different systems via its planes, which delineate dissimilar computation areas volumes. integration Georeference, mechanism provides unifying evidence successful landslide flood disaster management through envisioning streamflow generating (mainly SEOF) environment.
