Abstract
A system is disclosed that transforms offline maps into interactive online maps. In the system, geo-coordinate relationships are determined between geo-coordinates on a source map and geo-coordinates on an online reference map. An image of the source map is transformed to form an image of a modified source map having geo-coordinates that substantially align with corresponding geo-coordinates on the reference map. Modified source tiles are formed with the image of the modified source map and displayed on a portion of the reference map.
