I use GIS 1.8.
I have the need to be able to draw exact lines and shapes on a bing map. (This is to project a yet to be build greenhous project on a map to show what i would look like).
I have found the tool of Olivier Dalang (improved polygon capture) to be very usefull, since this tool enables me to draw lines while specifying the exact length and angle of the lines, and by doing so i build all walls of the greenhouse on the map).
Here is my problem. The plugin enables me to enter the length in 'units', and drawing a line of 1000 units makes me come up with a line of about 622 meters.
I cannot find the exact way to change or find out how to draw in meters.
Any help highly appreciated!
(If there are other tools for drawing 90 degrees angled lines to a map I welcome these too!)
