Map-Viewer

Description:

Offline satellite map viewer. Map image tiles are downloaded with a script and compressed into a SQLite database. The application uses these images for viewing through the use of mouse movements, increasing the quality of image as zoom is applied. There are some additional debug features, such as boundary information and a tile border option.
