UMapper is the first application of its kind; it is a visual, universal, web-based map authoring application. UMapper makes it easier than ever to create embeddable maps for Adobe Flash™ and distribute them through a website, blog, or social network. UMapper’s visual map editor enables users of any skill level to add points, draw shapes and add interactive overlays to a map.
