Lantea: Difference between revisions

Revision as of 23:21, March 31, 2012

Lantea is a fictional (Stargate: Atlantis) mostly-ocean planet on which the Ancients erected the artificial "island" city of Atlantis.

The Lantea concept is a web app for mapping and tracking that is targeted to run on B2G, but can run anywhere on modern browsers.

Currently, a Lantea Maps web app is hosted at kairo.at and listed in the Mozilla Marketplace (developer-only for the moment).

Base technologies:

OpenStreetMap tiles - for rendering maps (should be parameterized so that alternative tiles like Google Maps/Satellite can also be used later on)
Geolocation - esp. watchPosition() for tracking positions
indexedDB - for saving settings, current track, etc.
appCache - for locally caching resources so the app can be used offline
canvas - for displaying tiles and painting position/tracks
GPX format - for downloading tracks / storing them externally

Resources:

Canvas Slippy Map - a simple canvas-based OpenStreetMap map display
Slippy Map On Canvas - a more elaborate canvas-based OpenStreetMap web app that can do e.g. touch events for panning and has zoom buttons
Mappero (a.k.a. maemo-mapper) - a Maemo app that solved well what the Lantea app should provide on an HTML base
OsmAnd - an Android app that is similar
