Looking to view the SRTM data within Google Earth… see http://www.ambiotek.com/topoview (this will launch G Earth) – To use simply Fly To your location and click the nearest waypoint. You will then see a balloon which allows you to preview or download the five degree tiles of data. More documentation at http://srtm.csi.cgiar.org/

Are you still paying for SRTM DEM data??? Don’t be stupid man, check out this resource! Click on the SRTM30 tile to download the Digital Elevation Map (DEM) from the place you select. All the links will download the data from the USGS site: ftp://e0mss21u.ecs.nasa.gov/srtm/srtm30 – see the UI ast http://www.dgadv.com/srtm30/
This site provides FREE 30-arc-second elevation data with bathymetry for the entire world. The data was created based on the SRTM-30 data set, then holes were filled with GTOPO-30 data and bathymetry from various sources was used to replace the ocean areas. This data consists of 33 files of global topography in the same format as the SRTM30 products distributed by the USGS EROS data center. The grid resolution is 30 second which is roughly one kilometer. see http://topex.ucsd.edu/WWW_html/srtm30_plus.html of jump to the FTP server at ftp://topex.ucsd.edu/pub/srtm30_plus
Just checking out some of the awesomme IMS sites developed and maintained by Latitude Geographics. For a great example check out this Public Library Geographic Database (PLGDB) Mapping website at Florida State University – http://plgdb.freac.fsu.edu/. The interface is slick and simple. Nice, friendly features like adding bookmarks, print to PDF and grab data make the site quite useful. Check out an area of interest for numerous data themes and variables.
Some interesting housing stats recently revealed by the Census Bureau and the 2005 American Community Survey (ACS) data… hope you aren’t planning on moving to san Diego!

– Newport Beach and Santa Barbara, Calif., were the only two cities with a median home value of a million dollars or more
– median home value in San Diego jumped from $249,000 to $567,000 between 2000 and 2005
– highest real median rent percentage increases found in San Diego (27.2 percent)
