GTOPO30
Description: GTOPO30 is a global digital elevation model (DEM) with a horizontal grid spacing of 30 arc seconds (approximately 1 kilometer)
Authors: EROS, NASA, UNEP/GRID, USAID, INEGI, GSI, MWLR, SCAR
Link: http://lta.cr.usgs.gov/GTOPO30

SRTM15_PLUS and SRTM30_PLUS
Description: SRTM30_PLUS is a global topography data set with a grid resolution of 30 seconds which is roughly one kilometer. SRTM15_PLUS is an updated model based on V11 of the SRTM30_PLUS, and its grid resolution is 15 seconds.

Global Stress and Strain Rate Model

WSM
Description: The World Stress Map (WSM) is a global compilation of information on the crustal present-day stress field maintained since 2009.
Authors:  Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences 
Link: world-stress-map.org

GSRM
Description: GEM Strain Rate Model (GSRM v.2.1) is a large improvement on its predecessor, mostly because of the enormous increase in data. The data increase is large enough that the new model is almost exclusively based on the geodetic data alone, whereas the older model used faulting information and earthquake focal mechanisms as additional constraints.
