Map Graphic

Identifier:

net.refractions.udig.mapgraphic.mapgraphic

Since:

uDig 1.0

Description:

Provide visual feedback in the form of a map decoration (such as a scalebar or north arrow) where the visual does not do any data access. Also useful to visualisation of an in memory domain model - but please be careful to avoid any synchronization - it is often better to render from a cache then directly from object oriented code in active use.
