SRTM Enhanced Blue Marble Terrain Map of California

This terrain map of California was created by combining the NASA Blue Marble imagery with the global elevation data from the Space Shuttle Radar Topography Mission (SRTM).  The combination of these two data sets creates an amazing new way of viewing the Earth’s topography and landforms.

The SRTM elevation data is detailed enough that you can make out objects as small as freeways and levees and the Blue Marble imagery brings it all to life.

The California Terrain Map is available in four formats.

In case you’re wondering “What about the rest of the Earth?”……I’m working on it.  I’m hoping to have an global overlay at this detail in Google Earth within the next few weeks, but my lowly 6-year old single-core Pentium 4 takes its sweet time in processing the imagery.

I’m also thinking of doing individual maps of various states/countries in GeoPDF/GeoTIFF format since these would make nice base maps that can be used for many different purposes.

    Thanks these are great. You might consider renaming the files. I thought they were duplicates as my computer automatically renames duplicates to something similar or identical to your scheme.
