Desktop Geocoder


About the Desktop Geocoder

This tool is downloaded and installed on your desktop.  It geocodes a data table (i.e. table of addresses) from your local computer.  The addresses in your table are encrypted and securely sent to our servers and geocoded.  The geocoding results are then sent back to Desktop Geocoder and added to your original table.

This tool is secure and suitable for geocoding confidential or sensitive data.  We use standard encryption technology (Secure Sockets Layer or SSL) to ensure that communication between your computer cannot be interpreted.  Moreover, the addresses that are received by the server are only held during the electronic transaction and are never stored or warehoused in a database or the file system.

You can connect directly to a table of addresses in the following formats:

  • SQL Server 2000, 2005, 2008 and the express versions of 2005 and 2008
  • Microsoft Excel 2003 or earlier (.xls or .xlsx)
  • Microsoft Access 2003 or earlier (.mdb or .mdbx)
  • Comma-separated text file (.csv)
  • Tab-delimited (.txt or .dat)
