CDED (Canadian Digital Elevation Data)

The CDED (Canadian Digital Elevation Data) 1:50,000 and 1:250,000 files can be downloaded from http://www.geobase.ca/geobase/en/data/cded/index.html

These must be converted in the Pathloss program before they can be used.

Using CDED files with Pathloss 4.0

• Download and unzip the CDED files to your hard drive.
• In the Pathloss program select Configure-Terrain Database
• Select DTED-CDED indexed files from the Primary list
• Click the Setup Primary button
• Click the Set directory button. Set the directory to where the un-zipped CDED files are located and click OK
• Click the USGS to DTED button. A file selection dialog box will open, select the DEM files that you have downloaded and un-zipped and click Open. The files will be converted, added to the index and are ready to use.
