well you will need the real DEM ( Digital Elevation Map ) data for that area

start with
http://earthexplorer.usgs.gov/

the 7.5 ,15 and  30 arc second data is here
http://topotools.cr.usgs.gov/gmted_viewer/
http://topotools.cr.usgs.gov/gmted_viewer/gmted2010_global_grids.php

then remap that data into the l;ocal datum that that map is using
the NOT free and expensive ARC-Gis can do that and so can the FREE
G.R.A.S.S program or GDAL
http://grass.osgeo.org/

then you need to "Shade" the real elevation data

there are many ways to do that
