GISlite/TileZoom ViewerEntry ID: GIS_Viewer
Abstract: The GISlite / TileZoom Viewer is a java applet for displaying and manipulating vector graphics data such as points and poly-lines, and raster data such as maps and images. It allows for multiple sets of multi-resolution data with scale dependent features to be displayed together, layered one on top of the other. The viewer provides smooth pan and zoom and allows for individual layers to be turned ... on and off. It also supports web-based viewing of large zoomable TilePic images.
GISlite maintains a large range of functionality while being relatively small in comparison to its more full featured sibling, the GIS Viewer 3.0. It is also more widely useable, requiring only Java version 1.0.2 for better compatability with older browsers. An even smaller subset of the applet is available for use as a TilePic viewer. The viewer is highly modular and can be easily extended to add new data types and user-interface features.
