I’m using TrackOverlay to create GeoFencing features into my WinForms application. When I get the WKT though the TrackEnded event, the WKT does not create a square when you calculate the distances.
For example, when I draw a square on my map, I get the following WKT:
POLYGON((-82.0759586090482 40.9941991642239,-81.9876535169284 40.9941991642239,-81.9876535169284 40.9058940721042,-82.0759586090482 40.9058940721042,-82.0759586090482 40.9941991642239))
When you plot those distances (either using the GetLength() method in ThinkGeo or using this website: https://gps-coordinates.org/distance-between-coordinates.php) the sides of the square are not equal. One length comes out to 6.1 miles and the other comes out to 4.61.
I’m thinking that I might have to use some type of offset, but I’ve tried a few things and I can’t figure it out. Any help would be appreciated. Thanks
My map is setup to use DecimalDegree as the MapUnit: winformsMap.MapUnit = GeographyUnit.DecimalDegree;
Below is the TrackEnded method of how I’m getting the WellKnownText:
private void TrackEnded(object sender, TrackEndedTrackInteractiveOverlayEventArgs e)
shapeCurrentGeoFenceWellKnownText = e.TrackShape.GetWellKnownText();
