JViews Maps can merge vector, raster, and elevation data from multiple map file formats and storage locations. You can prepare a map using georeferenced data (that is, systems defining projection, ellipsoid, and/or datum information), and non-georeferenced map assets. For example, you can create a map with a UTM projection, import data from a CADRG map (with an Arc projection), a shape file based on a Lambert projection, and overlay these with a JPEG image.
