I had a query regarding Zooming.
1) I bounded the selected area by giving the follwoing statements.
Dim box As New SharpMap.Geometries.BoundingBox(Min x, Min Y, Max X, Max Y)
But while clicking on ZOOMIN, My requirement is, I have to ZOOM only this selected area. But it is zooming the entire map
2) I have to get Gridlines on the entire map like a graph having 30 miles distance for selected BoundingBox.
kindly help me anyone
