About the application:

A light pollution map to assist you search the best places for observing or to buy that excellent piece of land you always wanted for stargazing or just to satisfy your curiosity. It started out as a web application you might have heard about at www.lightpollutionmap.info, but now it's also accessible as a mobile application. It displays VIIRS/DMSP/World Atlas overlays/IAU observatories and the player measurements overlay over Microsoft Bing base layers (street and hybrid Bing maps). It is a port of www.lightpollutionmap.info, so it has practically the same functions and look, but features an offline mode and no advertisements. The basic use is to present VIIRS/DMSP data in a friendly manner, but over time it also included some another interesting overlays that concern light pollution like SQM/SQC, Globe Atlas 2015 zenith brightness, clouds and IAU observatories. If you have a permanent SQM reader installed you can add it to the map by sending me an e-mail. Annual VIIRS comparisons are to be avoided as there are too a lot of factors involved by just doing a direct comparison. If you wish an analysis of radiance (VIIRS/DMSP) changes over a period of time, then please use the Lighttrends application (look under Help). Functionalities: - VIIRS, Sky Brightness and Cloud layers - Street & Terrain base maps - Cloud animation for the latest 12 hours - Receive detail radiance and SQM values from layers at a click. For Globe Atlas 2015, you also receive Bortle class estimation. - SQM, SQM-L, SQC, SQM-LE, SQM readings submitted by players - Submit your own SQM (L) reading - Observatories layer - Save your favorite places - Distance measurement program with azimuth angle report - Offline mode (Sky brightness map and a base map are saved to your device, so it will be displayed when you are offline) Permissions: - Place (to present you your place) - Network state (used whether to display online or offline maps) - Read & write to external storage (used to save offline maps)
