The general idea is this application is run on something like a Raspberry Pi (could be the same one that's running [radiosonde_auto_rx](https://github.com/projecthorus/radiosonde_auto_rx)?) and is accessed from a tablet or laptop computer via a web browser.
For this to run, you will need the horuslib library installed. Refer to the [Installation guide](https://github.com/projecthorus/horus_utils/wiki/1.-Dependencies-&-Installation).
To do this you need cusf_predictor_wrapper and it's dependencies installed. Refer to the [documentation on how to install this](https://github.com/darksidelemm/cusf_predictor_wrapper/).
* Copy the 'get_wind_data.py' script from cusf_predictor_wrapper/apps into this directory.
You will then need to modify the horusmapper.cfg Predictor section setting as necessary to reflect the predictory binary location, the appropriate model_download command, and set `[predictor] predictor_enabled = True`
You can then click 'Download Model' in the web interface's setting tab to trigger a download of the latest GFS model data. Predictions will start automatically once a valid model is available.
At the moment Chasemapper only supports receiving chase-car positions via Horus UDP messages. These can be generated by the [ChaseTracker](https://github.com/projecthorus/horus_utils/wiki#chasetracker--chasecar_nogui) application from horus_utils. This application can also plot your position onto the tracker.habhub.org map, so others can see when you're out balloon chasing.
Eventually support will be added to get car positions from either GPSD, or from the client's device.
## Offline Mapping
(This is a work in progress)
By default Chasemapper is configured to use the online OSM and ESRI Satellite tileservers. There is also an 'offline OSM' entry in the map layer list (top right of the page), which attempt to gather maps from `http://server_ip:8080/roads/{z}/{x}/{y}.png`. I've been doing some testing with using [Tilestache](http://tilestache.org/) as a lightweight tileserver, serving tiles from mbtiles files. A guide on how to cache up OSM data for use with Tilestache is TBD...
(If anyone has managed to get ECW support working in GDAL recently, please contact me! I would like to convert some topographic maps in ECW format to tiles for use with Chasemapper.)
