Comparative analysis of SRTM and DEM-Ar 2.0 Digital Elevation Models for the identification of areas of danger from flooding and waterlogging in an area of plain

Mostrar todas las versiones(2)

Floods and waterlogging in urban centers are one of the main dangers in the Province of Chaco (Argentina). The objective of this work is to compare the Digital Elevation Models (DEM) SRTM distributed by the Geological Society of the United States and DEM-Ar 2.0 available through the National Geograp...

The objective of this work is to compare the Digital Elevation Models (DEM) SRTM distributed by the Geological Society of the United States and DEM-Ar 2.0 available through the National Geographic Institute of the Argentine Republic, both of 30 meters of spatial resolution, to the identification of potential flooding and waterlogging areas in the city of General San Martin (Chaco). To achieve this objective, a visual and statistical analysis was carried out at the municipal and urban levels, the quality of the MDE was evaluated by calculating the Mean Square Error (MSE) and finally, the information obtained was complemented with mapping of the local hydrography to identify dangerous areas. The results indicate that both DEMs are useful alternatives when using altimetry data from the studied region. Statistically they do not present significant differences, the recorded errors are between 2 and 5 meters, being better the vertical precision of the DEM-Ar-2.0. En este trabajo se presentan los procedimientos y resultados alcanzados de la comparación de modelos digitales de elevaciones (MDE) obtenidos a partir de diferentes fuentes globales de fácil acceso, a fin de obtener un producto que se adapte a los requerimientos de los estudios de riesgo hídrico de un área urbana de llanura en la Provincia del Chaco, Argentina. Para la construcción de los modelos digitales de elevaciones, basado en una perspectiva geotecnológica, se utilizaron herramientas de análisis espacial de los Sistemas de Información Geográfica donde se compararon cinco MDE: SRTM disponible a escala global, IGN-AR de alcance nacional, y tres construidos a partir de interpolación con los métodos IDW, kriging y topo to ráster en base a datos altimetricos de Google Earth. Los resultados alcanzados demuestran la necesidad de construir insumos para el modelado cartográfico de base para la toma de decisiones a partir de fuentes globales o locales que se adapten a la realidad de los ambientes urbanos.
