DEM and associated kinematic GPS coordinates of September 2009 survey of the salar de Uyuni, Bolivia

This dataset consists of two parts:  1) the post-processed kinematic GPS coordinates of a September 2009 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 design are identical to that from an earlier survey in 2002 and 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 DEM is described in the manuscript "A Terrestrial Validation of ICESat Elevation Measurements and Implications for Gloval Reanalysis" (doi: 10.1109/TGRS.2019.2909739). 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.
