LatLon2XY.centered function

computes the centered coordinate transformation from lat/lon to map tile coordinates

The function LatLon2XY.centered(MyMap, lat,lon,zoom) computes the coordinate transformation from lat/lon to map tile coordinates given a map object.

LatLon2XY.centered(MyMap, lat, lon, zoom)

Arguments

• MyMap: map object
• lat: latitude values to transform
• lon: longitude values to transform
• zoom: optional zoom level. If missing, taken from MyMap

Returns

properly scaled and centered (with respect to the center of MyMap ) coordinates - newX: transformed longitude

• newY: transformed latitude
