OpenLayers

Purpose

This is a pure Javascript wrapper for certain basic functionality provided by the OpenLayers framework. It saves writing and maintaining multiple apps to do the same or similar jobs. The application area targetted here is that of Biodiversity.

Contexts

Context is indicated by URL and controls the extent of the map and the preset layers (boundary or overlay) available.

Here are some examples to try.

https://liveservices.info/live/apps/ol/	base URL - prompts for context (try WALES)
https://liveservices.info/live/apps/ol/?SW	the SW region, with some preset layers
https://liveservices.info/live/apps/ol/?GCER&sssi	SSSIs in the Gloucestershire (records centre) region
https://brerc.info/live/apps/ol/?BRERClocalsites	BRERC local sites (authkey required)
