Psgeo: Activity location library

Psgeo is a small Javascript library for managing and filtering information for web applications that deal with, e.g., sports activities in different locations. Its primary purpose is to be able to display maps of activities at those different locations, while allowing for smart filtering.

Psgeo has been used for tracking skiing activities by Planetskier and caving by Luolaseura and Planetcaver. For an example application, see Ralf Strandell's Finnish caves page at the on the Luolaseura web.

Psgeo is based on Activity JSON, a simple format that allows a server to provide information about activities and their geographic positions to a web application running in a browser.

For more information on the usage and API of Psgeo, read the Psgeo Usage Introduction.

Psgeo was initially written by Jari Arkko, but there has also been contributions by Ralf Strandell.
