Missile TID
This library is designed to look for traveling ionospheric disturbances (TID), a phenomenon caused by space launch vehicles, and large ballistic missiles (among other things) when they travel through the ionosphere.
Setup
Some platform-specific dependencies must be installed first. Once this is done, you should be able to install the requirements with
python -m pip install -r requirements.txt
Ubuntu (20.04)
If in doubt, check the Dockerfile for an exact build recipe, as that will be based on an Ubuntu image.
sudo apt install gcc g++ libcurl4-openssl-dev libgeos-dev
MacOS (Monterey/Ventura)
Most issues with getting up and running on MacOS are related to the Shapely library, which Cartopy imports. If you have issues installing either of these, please see more about the pre-reqs here: https://scitools.org.uk/cartopy/docs/latest/installing.html. You should however only need the geos library, which can be installed with brew or macports:
brew install geos
If you still run into issues when producing the plots, for example with the error:
OSError: Could not find lib geos_c or load any of its variantsyou must have a Python executable that is running on the same arch as the geos binaries
you installed using brew. This may mean you have the wrong Anaconda version (x86_64 vs arm64),
as an example.
Running the demos
There are currently two demos available to produce animations of the TID about an area:
demos/vandenburg.py: Displays an animation showing the detection of a Falcon 9 launch out of Vandenburg, CA on the 12th of June, 2019.demos/live.py: Monitors for potential launches near the Korean peninsula.
Common errors
- If you receive the error:
free(): invalid sizewhen producing the animation, then you must compile Cartopy from source, and not from a built wheel. Eg:pip install --upgrade --no-binary shapely shapely==1.8.4

Because of the refactor, this branch wiped out a lot of author information.
