Drop time-enabled geodata (KML, GeoJSON, GPX, CSV) into the browser, get a timeline-map. Uses Redis key-value store, can import your public OpenStreetMap traces
Crunchtime
Experimental timeline-map setup. Drop time-enabled map files onto the page. Accepts multiple files, multiple formats, and combining multiple formats.
The Basic Idea
Trim and Simplify GPS Traces
Import Traces from OpenStreetMap
Currently supports:
-
GPX files
-
KMLs using <coord> and <when> tags
-
KMLs using <begin> and <end> tags
-
Any CSV with valid latitude, longitude, and time readable by JavaScript Date( TIME * 1 ) or Date( TIME )
-
GeoJSON with a start and/or end property. Assumes 100-5000 are years, other numbers can be converted using 'new Date(Number)', and any strings can be converted using 'new Date(String)'
-
GeoJSON with no time information (appears at all times)
-
KML <Point>s and <Polygon>s with no time information (appears at all times, does not include styles or other KML properties)
-
Your OpenStreetMap traces (privacy set to identifiable)
Will research:
- KML geometry support beyond Point and Polygon
Server-side: Node.js and RedisToGo
After you drop a time-enabled file onto the page, it will be POSTed to a simple Node.js server for storage in a Redis key-value database.
The HTML5 History API automatically updates the URL in your browser. Copy this URL to share your map.
