This is a website that pre-generates terrain files for Ardupilot. The user enters in the details of the area they wish the generate terrain for, then the website will generate a terrain.zip file containing the relevant dat files. The user will download this file and then then need to unzip to a "terrain" folder on the SD card in their flight controller.
To ensure the website operates responsively, the terrain for the whole (-60 -> +60 latitude for SRTM3, -84 -> +84 latitude for SRTM1) world must be pregenerated. This will take some time.
Run offline_gen.py to download the SRTM files from ardupilot.org and convert them to the dat
file format. These files will be stored in the processedTerrain folder.
This website uses the flask library.
To install dependencies:
pip install -r requirements.txt
To run:
python3 app.py
The unzipped processed files are temporarily stored in ./outputTer-tmp. These are deleted upon the zipping into a single downloadable file
The downloadable files are stored in ./outputTer
Each user request is given a UUID, which is incorporated into the folder/filename of the terrain files.
To run the unit tests, type pytest
A systemd service is provided for running the WSGI server.
