Terrain Data Sources
Data available through automatic download
Global Terrain Data Sources
SRTM 1"
Global 1" DSM between 60 degrees north and 60 degrees south. Pathloss 6 can automatically download and configure SRTM terrain data.
https://www2.jpl.nasa.gov/srtm/
This data is normally used as a clutter source, but can be used as terrain data.
ASTER 1"
Pathloss 6 can automatically download and configure ASTER terrain data. Downloading 1" ASTER data requires a NASA Earthdata Login username and password. To obtain a NASA Earthdata Login account, please visit:
https://urs.earthdata.nasa.gov/users/new/

CGLC100 - Copernicus Global Land Cover 100m
Global Land Clutter data in 100m resolution. Pathloss 6 can automatically download and configure CGLC100 terrain data.

GeoJSON Editor
Create buildings or other features in the GeoJSON format and use in Pathloss 6. This is useful for adding proposed structures or structures that may not exist in other data sources. See Vector Data for instruction on using GeoJSON data
3D Building Data
3D Building data for the world in GeoJSON format. See Vector Data for instruction on using GeoJSON data
North America - US, Canada and Mexico
In addition to the the Global sources, the following data is available for North America:
USGS NED 1"

USGS LIDAR Explorer
Very high resolution DSM data. This data can be used as Clutter 2 data source to provide very detailed clutter heights.
The data must be processed and output as a GeoTIFF file either on the USGS site or by using PDAL locally.
