प्रतिछाया कोहरा युद्ध की अवधारणा पर आधारित एक मुक्त अन्वेषण आवेदन है।

Umbra is a exploration application based on the the Fog Of War concept used in strategy games. On the map the unexplored area is displayed grayed out while the explored part is clear. Since the unexplored parts of the map are shown greyed out you can use this application to explore a city or an area.

The application needs a GPS fix in order to mark an area as explored as the accuracy from the other location sources is not good enough. Currently the minimum accuracy needed for saving the explored area is set at 100 m (300 feet). The accuracy is displayed as a disc around the current position.

The explored area of the maps is persistent between applications restarts so you can explore an area, stop Umbra and then start it again.

This is a work in progress so if there are any bugs please report them by mail to [email protected] or by going to https://github.com/unchiujar/Umbra/issues

The application is open source, you can view the code on Github at https://github.com/unchiujar/Umbra
