I have a MapControl and would like to know how many degrees are currently shown on the x and y axes.
360 degrees are shown on the x axis (longitude)
~90 degrees are shown on the y axis (latitude)
(The zoom level is 3.2 and it's max zoomed out)
~220 degrees on the x axis (longitude)
180 degrees on the y axis (latitude)
(zoom level: 1.7; max zoomed out)
I tried calculating the current degrees on the x axis using following code:
double dist = 360 * Math.Pow(0.5, macSurrounding.ZoomLevel - 1);
You should use the MapControl's GetLocationFromOffset method to calculate the geographic coordinates of the south-east and north-west corner points of the current map viewport. The width and height of the viewport would be the latitude and longitude differences of these points.
Geopoint northEast; Geopoint southWest; map.GetLocationFromOffset(new Point(map.ActualWidth, 0), out northEast); map.GetLocationFromOffset(new Point(0, map.ActualHeight), out southWest); var width = northEast.Position.Longitude - southWest.Position.Longitude; var height = northEast.Position.Latitude - southWest.Position.Latitude;
