hi You can calculate ranges.

e.g: Washington's center (10, 10)
New york (20, 20)

C#

float calculateRange(float latit1, float longit1, float latit2, float longit2)
{
        float rx = (latit1 - latit2)* (latit1 - latit2);
        float ry = (longit1 - longit2) * (longit1 - longit2);
        return Math.Pow((rx + ry), 0.5);
}
