Distance between two points

[Carlos Rodriguez]

You can get the ditancia between two points on the map? No matter if it is not accurate, albeit approximate.

Hi Carlos,

You can use LocationRect object for this purpose:

Location location1 = new Location(37.7040701207995, -121.882780875908);
Location location2 = new Location(37.7140701207995, -121.872780875908);

Location northEast = new Location(
    Math.Max(location1.Latitude, location2.Latitude),
    Math.Max(location2.Longitude, location2.Longitude));

Location southWest = new Location(
    Math.Min(location1.Latitude, location2.Latitude),
    Math.Min(location1.Longitude, location2.Longitude));

LocationRect rect = new LocationRect(northEast, southWest);
rect.MapControl = this.radMap;

double distance = Math.Sqrt(rect.Width * rect.Width + rect.Height * rect.Height);

It's pretty simple!

thank you very much Andrey!

I Have problems in this line:

LocationRect rect = new LocationRect(northEast, southWest);

I get the following manner:

LocationRect rect = newLocationRect(northEast, southWert, With, Height),I can do in this case?


[Carlos Rodriguez]

The above procedure gives me a result in decimal, how I can make the conversion to meters?

Hi Carlos Rodriguez,

It seems you are using quite old CTP version of the RadMap control. Since first official release of the RadMap in 2010.Q1 the LocationRect class has 2 constructors:

1. LocationRect(double north, double west, double width, double height)
2. LocationRect(Location northEast, Location southWest)

In order to get distance between 2 geographical locations you must use second type of the constructor. It creates rectangle using geographical locations. You can't use the first type of the constructor for this purpose.
