[Qgis-user] how to size a vector layer polygon

[Fred LaPlante]

I am trying to adjust a set of property maps based on georeferenced 
scans of paper maps. While the georeferenced images aren't bad as 
pictures, they are poor regarding dimensional accuracy.

I have traced the geoTiff images onto a vector layer of polygons. I have 
set my project to use a projection (UTM) that enables me to measure 
distances on a map in meters or feet. The original paper maps have 
dimensions shown. I now want to adjust the length of the various 
polygons to their correct length. But I cannot find a way to show the 
dimensions of a line as I draw it  I really do not want to use the 
measuring tool in a trial and error process as there are hundreds of 
polygons to be corrected.

Is there some plugin I have overlooked? I know there used to be an 
Azimuth and Distance (v. 0.3) plug-in, but that now shows up as 
incompatible with qGIS1.3.

By the way I am using Win XP as OS.
