Light pollution map vs Action Tour Guide: Experiences Usage & Stats

A light pollution map to help you find the best locations for observing or to buy that perfect 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 available as a mobile application. It displays VIIRS/DMSP/World Atlas/Aurora overlays, IAU observatories and the user measurements features over Microsoft Bing base maps (road and hybrid Bing). It is a port of www.lightpollutionmap.info, so it has practically the same functions, but features an offline mode and no advertisements. The primary use is to show VIIRS/DMSP data in a friendly manner, but over time it also included some other interesting overlays that concern light pollution like SQM/SQC, World Atlas 2015 zenith brightness, clouds, aurora and IAU observatories. If you have a permanent SQM reader installed you can add it to the map by sending me an e-mail. If you want an analysis of radiance (VIIRS/DMSP) changes over a period of time, then please use the Lighttrends application (look under Help). Please send comments and requests for new features via email (look below for developer contact) Functionalities: - VIIRS, Sky Brightness, Cloud coverage and Aurora forecast layers - VIIRS and Sky Brightness layers can be displayed also in color blind friendly colors - Road & Satellite base maps - Cloud animation for the last 12 hours - Get detail radiance and SQM values from layers at a click. For World Atlas 2015, you also get Bortle class estimation. - SQM, SQM-L, SQC, SQM-LE, SQM readings submitted by users - Submit your own SQM (L) reading - Observatories layer - Save your favorite locations - Distance measurement tool 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: - Location (to show you your location) - Network state (used whether to display online or offline maps) - Read & write to external storage (used to save offline maps)
