Overview

MB-Ruler is a Windows application, that was originally designed to measure distances and angles on the screen.

Since MB-Ruler 4.0 measuring distances in OSM data is supported, too.

MB-Ruler has no own renderer but uses the prerendered tiles of the OSM servers.

Features:

measure distance between two points
measure length of a polyline
draw the measured distance (section of a great circle)
for users testing GPS based applications: MB-Ruler can generate NMEA data and write it to a COM port. This data can be used by an other application to test it's GPS functionality (details in the MB-Ruler help file)

MB-Ruler 4.0 can be downloaded from the its download site

MB-Ruler is freeware for non-commercial use. An enhanced shareware version MB-Ruler Pro is available, too.
