ArduPilot Terrain Generator

Use this to generate terrain to put on your SD card. There are 2 dataset versions available:

• SRTM3: Based on NASA's SRTM data and has 100m (3 arc-second) horizontal resolution, with data above 60N and below 60S filled from the SRTM1 data. It covers all areas between 0 and 84 degrees North/South latitude.
• SRTM1: Based on JAXA's ALOS dataset and has 30m (1 arc-second) horizontal resolution. It covers all areas between 0 and 84 degrees North/South latitude.

Multiple generated files of the same dataset version can be combined on the SD card.

Compatible with Ardupilot 4.1+

To download entire continents of SRTM3 terrain data, see here.

If using the SRTM1 data, set ArduPilot's TERRAIN_SPACING parameter to 30 before loading the data to the SD card. For SRTM3 data set TERRAIN_SPACING to the default of 100.
