Description

This dataset consists of two parts:  1) the post-processed kinematic GPS coordinates of a September 2002 survey of a 45 x 54 km region of the salar de Uyuni, Bolivia.  2) a digital elevation model (DEM) of the salar de Uyuni surface derived from those kinematic GPS data.

Details of the survey and DEM generation can be found in the manuscript, "Topography of the salar de Uyuni, Bolivia from kinematic GPS" (doi: 10.1111/j.1365-246X.2007.03604.x).  The only difference between this dataset and one described is that the DEM was generated from fitting two-dimensional Fourier basis set with parameters: L_x = L_y = 70000 meters, m = n = 10.  This results in a basis set with a nominal resolution of 7 km, which is almost identical to that used in the dataset shown in the manuscript.
