Currently, TimeMap Viewer software supports the delivery and display of local and remote bitmap datasets in .jpg (JPEG) and .sid (MRSID) formats. These raster images require "worldfile" information in their metadata so the TimeMap viewers can place the images in their correct location on the MapSpace. For instructions on generating worldfile metadata for your raster image, see the next sectionon using the TimeMap application called TM GeoRegistration.
