# CUSF Standalone Predictor - Version 2
|
|
|
|
Working on improving the Cambridge University Spaceflight landing predictor, a web-based tool for predicting the flight path and landing location of latex balloons.
|
|
|
|
## Install
|
|
|
|
The source for the predictor itself is in `pred_src/` and instructions for building it can be found there.
|
|
|
|
The `predict/preds/` and `gfs/` directories need to have rwx access by the PHP interpreter and the `predict.py` python script. You will need to install the following python packages: pydap, numpy, json, simple-json. We use `at` to automatically background the predictor, so you will need that installed.
|
|
|
|
Other than that, just clone this repo to a non web-accessible folder and create symlinks to the `predict/` and `hourly-predictions/` directories in the repo.
|
|
|
|
There are useful configuration options in `predict/includes/config.inc.php`.
|
|
|
|
## Information
|
|
|
|
A cronjob should be run to delete directories in the `preds/` directory after a given number of days, probably 7. Predictions older than 7 days are useless anyway.
|
|
|
|
The directory names are UUIDs comprised of an SHA1 hash of the launch parameters, and re-running predictions will overwrite data in the existing directory, rather than create a new one.
