Cumulated subsidence maps of Mexico city

Abstract

A set of 38, 30 x 30 m resolution rasters of the subsidence over Mexico City and part of its metropolitan area, has been made available through this work. Subsidence rates in Mexico, one of the most populated cities in the world, reaches up to 0.4 m/yr, mainly due to soil compaction led by over exploitation of the Mexico Basin aquifer. To accurately map the spatial and temporal evolution of this phenomena, a set of Synthetic Aperture Radar images has been processed through interferometry and the results have been formatted as rasters that can be read and analyzed on any Geographic Information System. Moreover, the whole set of rasters can be visualized as interactive animated time series of the subsidence, through the journal platform.
