JOSM/Plugins/Tracer

Tracer is plugin for one-click tracing objects (mainly buildings) from a base map. As a base map, Czech cadastral map, RÚIAN and LPIS can be currently used.

Currently, there are several plugins named "Tracer" in the plugin repository of JOSM:

• Tracer – old plugin, requires custom tracing server (beta6, beta 2 sources) to run. The server needs .NET or MONO framework (this is not what you usually want).
• Tracer-testing – enhanced tracer for tracing from Czech cadastral maps, RÚIAN and LPIS (this is what you probably seek for).
• Tracer2 – German fork of the original Tracer, aligned to German specific needs.
