The Geospatial Plugin adds new primitives to the TiddlyWiki platform to enable non-developers to build sophisticated interactive geospatial applications.

It incorporates a number of third party libraries and online services:

• Leaflet.js, an open source library to display interactive maps
• Turf.js, an open source library to perform geospatial calculations with GeoJSON objects
• TravelTime, a commercial API for geocoding, routing and isochrones
• Flickr, a free API for retrieving geotagged photographs
• OpenLocationCode, Google's open source library for converting to and from Open Location Codes (also known as PlusCodes)
