Determinación del área de afectación causada por construcciones urbanas sobre el humedal de Córdoba de Bogotá D.C. a partir de análisis cartográfico multitemporal (1970-2017)

Abstract

The objective of this work was to determine quantitatively the affected area at the wetland Cordoba of Bogota D.C. as result of the planned and legalized in any cases urban expansion that affected the city in the period encompassed from 1970 to 2016, only the urban constructions that cause the greatest impact were considered. A multi-temporal cartographic study was carried out using air images taken during the time previously mentioned. The value of the affected area was determined by applying geospatial delimitation models from different sources, such as topographic, cadastral and the image processes, using specialized software in geographic information, image analysis (RASTER) and vector information. It was obtained that the wetland was affected by 83.76%, caused by the built-in urban developments from the initial time to the current time.
