FlightGear NavDb

• This project imports xplane data and delivers a json api
• Visit http://navdb.freeflightsim.org

The project has two core parts

• navimport/ - a bunch of python scripts to import the data
• navdb/ - a golang web server using the revel framework

Mission

This is a bleeding edge idea to serve a stable and regular updated "feed" fo FlightGear pilots

• it takes the latest xplane data, which is a huge tarball.zip
• and imports using python and the navimport/* hacks -- into a postgis database -- the postgis db is setup with views and -- extract spatial data from the geometry machine -- and convert to values eg lat/lon on the fly
• The golang application replies to queries for this data in various formats -- at http://navdb.freeflightsim.org/ -- and soon websocket, kml and xml feed
• Next Gen -- move all shell import from python to golang/revel and remote execution -- automatic update of data, ie same as before -- flag changes, new or moved,dead = latest -- move import routines to golang, maybe manage

From Revel:

• yaml config and multi config
• create json api autodocs
• use pongo templating for inhertitance,
• create jinja2 interface so I can share same templates ;-)))
• replace fab with app or alike

Requirements:

• A linux server with root/sudo access and gcc
• Postgres 9 + Postgis2 database
• python 2.6+ - for importing
• golang 1.3 - for development
• revel app framwork - github.com/revel/revel

Run:

revel run github.com/FreeFlightSim/fg-navdb

or for "config" and "port"

revel run github.com/FreeFlightSim/fg-navdb dev 7777

Then visit http://localhost:777/controlpanel
