NOTE: This is a development branch of MapView and is a complete rewrite of
anything yet-used in production. The master branch contains the old rendition
of MapView, but works entirely differently. New development effort is being
focused on this (v3) branch, however it is not yet production-ready.
MapView is a Haskell library for building GPS-based tracking systems, based on telemetry downlinks (usually via RF, and typically done via amateur radio).
The primary usecase is for high-altitude balloon tracking.
Given any kind of downlink which includes GPS coordinates (and other optional information), the goal of MapView is to make it easy to write programs to process this data. MapView itself contians a "standard library" of callback functions which can be called at any point where data is to be processed (for example, before it is parsed, after it is parsed, or after other callbacks are run).
We provide a set of libraries and callback functions, you use them as you choose. Your "configuration file" is actually the program that does the work, in a vein similar to how Xmonad works.
What you do with the data is up to you, though we also provide (in other repositories) some standard extensions to this core library. For example, we have a library (mapview-websocket) used for sending parsed telemetry packets to websocket clients in a structured way, useful for live-plotting the latest location on a browser-based map.
In mapview-noexc, we provide full configurations (programs) that we (the Northeast Ohio Experimenter's Club) have used in production, along with a set of callbacks specific to our flights. These can be used by you to inspire the creation of new callback functions, or pulled directly from our repository, as you see fit.
MapView is written and maintained by Ricky Elrod and NOEXC originally for the University of Akron Amateur Radio Club (W8UPD), and released under the MIT license. It is now maintained under the name of the Northeast Ohio Experimenter's Club.
We use the system in conjunction with RTTY telemetry, but it is easy to modify the system to work with other forms of telemetry.
