It is proposed a methodology to get landform of an area by using GIS techniques and a verification afterwards by photographs taken from several highways and motorways. Within the catalog of geographic features that serve to define a specific landscape of an area, this paper proposes the study of the landform. It is about mapping by using Geographic Information Systems, specifically the ArcGIS 9.3 (ArcMap and ArcCatalog). To do this, it is necessary to use both raster and feature formats. The methodology using of various coverage of the Alicante province, extending from the contour, vertices surveying, dimensional points, administrative boundaries of the province to rivers and reservoirs. All this information has been provided by the National Center for Geographic Information. In this manner, we obtain a Digital Terrain Model corrected hydrogeologically to 1:25000. Starting off of this digital terrain model - which has been calculated through the actions explained above- we used several tools of ArcGIS 9.3, including: neighborhood focal statistcs, reclassify, slope, clip, intersect, dissolve, etc. in order to calculate relative relief, slope and neighbourhood analysis radius. With these parameters we obtain a Landform Classification of Alicante province (Spain). Afterward, we contrast the landform result with a pictures taking from several highways and motorways in Alicante in order to identify if this classification is correspond with the reality. As a result, we obtain an Automatic Landform Classification of Alicante in 1:25000, and properly methodology to do this delimitation because it has been contracted with the real landform by pictures. After the verification with the reality, the result map is be able to extrapolate the methodology applied to others places with similar or different superficies and also with another type of topography. It is only necessary to adapt some parameters depending of the project scale. | |
