Measure the distance in MapWindow

Nov 15, 2012 at 1:21 PM

Hello, Is there a way to measure the distance from point to point, in meters, killometrov
For example, draw a point, and then another, they are connected by a line, and outputs the distance

MapWindow has a measurement plug-in you can use.
Sergei is currently working on adding measurements capabilities to MapWinGIS, but this will need some time.

You can also create a temp shapefile, add the points as a line shape and use Shape.Length():

Andrey53, careful what you consider distance. In most GIS, including MapWindow I believe, it is calculating the distance as traveled on the line that is drawn on the screen. That is not the same as one would term a "great circle" or "geodesic" distance which would be a more realistic path taken on a sphere or spheroid. For small distances the difference is negligible but for large distances the difference in path is appreciable.

For your information:

For MapWinGIS v4.9 Sergei added Utils.GeodesicDistance (changeset #69545).

"Utils.GeodesicDistance method for distance calculation between two points specified in decimal degrees (from GeographicLib by Karney). See"

That is good news! I've always wanted something like that function.
