The map displays VIIRS/World Atlas/Clouds/Aurora/IAU observatories and the user SQM measurements. 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. Please send comments and requests for new features via email (look under help) Functionalities: - VIIRS, Sky Brightness, World Atlas 2015, Cloud coverage and Aurora forecast layers - VIIRS and Sky Brightness layers can be displayed 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 Sky brightness/World Atlas 2015, you also get Bortle class estimation. - SQM, SQM-L, SQC, SQM-LE, SQM readings submitted by users - International dark sky parks overlay - Submit your own SQM (L) readings - Observatories layer - Save your favorite locations - Distance measurement tool with azimuth angle report - All-sky view of light pollution with real horizon - Offline mode (Sky brightness map and a base map are saved to your device, so it will be displayed when you are offline)

Version History - Feature filters can be now be saved (settings). Name field also supports wildcard searching for example '*town OR john*' will display 'Smalltown' and 'Johnstown'. - 'My locations' can now be saved (and edited) and restored from a file. - 'My locations' now also available as a feature overlay, so you can view them on the map. - Changing dates in the calendar widget doesn't open virtual keyboard anymore (except when you tap on hour/minute fields). - Other minor changes and bug fixes. 1.1.39 21h ago - Sky brightness simulation: added a function that generates an all-sky image that takes into account the drawn polygon radiance modification. That way you can see the effect of the modification on the sky brightness distribution across the entire sky, not just at the zenith. - Added NELM as an alternative unit for sky brightness display for Sky brightness and World Atlas overlays. You can toggle between NELM and MPSAS by clicking the 'SQM' text in the point info window. - Added a 'Save' button to the generated all-sky image, so you can save it directly to your device. - Other minor fixes. 1.1.38 May 8 - All-sky image now has two views: Fisheye and panoramic view. - Other fixes and improvements. 1.1.37 Apr 22 - Added 2025 VIIRS and Sky brightness overlays. - When area statistics are shown for Sky brightness/World Atlas, locations of the minimum and maximum values are now also marked on the map. - Other minor fixes and improvements. 1.1.35 Mar 20 - Bortle class display fixed. - Fixed the issue with sorting 'My locations' when a new item is added. 1.1.34 Mar 10 - New Sky brightness overlays (all years) - Render All-sky image at a specified location (with terrain) - Added International Dark sky parks polygon feature overlay - Redesigned offline mode (supports all Sky brightness overlays and point information) - Added basemaps from Apple and OpenStreetMap - Other improvements and bug fixes 1.1.33 Mar 7 - New Moon tool that displays realistic moon state (phase, illumination, libration, relative size), moonset/moonrise times and other properties at any given moment and location on the planet. - Added NOAA 3-day Aurora forecast (turn on Aurora layer and a link should be visible under the dropdown menu) - Various bugfixes 1.1.31 11/19/2025 - Changes to the user interface - Added 'Zenith brightness simulation' tool - Added 'Find closest dark' site tool - World Atlas 2015 overlay has some new additional display options - Viewing SQM-LE charts received some performance upgrades 1.1.29 09/29/2025 - VIIRS overlays now use Black marble v2.0 instead v1.3 data - Added VIIRS 2024 - Basemaps and search providers changed because Bing Maps for Enterprise will be discontinued on June 30th 2025 1.1.25 06/12/2025 - Added 2023 VIIRS overlay - Other minor fixes 1.1.22 07/21/2024 - VIIRS chart now has an option to display monthly values - Fixed trailing artefact produced by the popup window on some devices - Fixed the issue of previously downloaded offline maps not showing after app update - Fixed the issue of search bar not showing when there are too many users on the server 1.1.21 08/18/2023 - VIIRS 2022 added - Search for places now first searches through Geonames database and if it fails it will search Bing's database - Other minor fixes 1.1.18 05/29/2023 - Added exponential trend (annual % change) to VIIRS radiance chart - Fixed the issue of non working offline mode in the last version (re-download the cache if not working) 1.1.17 08/11/2022 - VIIRS data source is now NASA instead of NOAA - Fixed the issue with adding a marker to "My locations" 1.1.16 04/15/2022 - Fixed elevation units when imperial units are selected in settings 1.1.14 02/12/2022 - VIIRS 2021 overlay added 1.1.13 10/24/2021 - New option under settings to display VIIRS/World Atlas overlays in a color blind friendly style - Enabled landscape mode for iPad - Fixed a bug from previous release where basemap was not displayed in offline mode - Other 1.1.10 05/10/2021 - New VIIRS overlay (2020) - Search is now using Geonames database instead of Microsoft service 1.1.9 01/20/2021 - Minor bug fixes 1.1.8 12/29/2020 - Added high DPI base map option under settings, which should provide larger map labels (especially if you zoom in) 1.1.7 12/15/2020 - Map navigation and help menu fix for iOS 12.x - Other minor cosmetic changes 1.1.6 11/10/2020 - Added support for dark mode (iOS 13+) - Minor bug fixes 1.1.5 11/05/2020 - SQC images can now be zoomed in - Fixed a few broken links - Fixed a bug that would sometimes show a previous spatial query instead of a current one 1.1.4 10/08/2020 - New Aurora forecast overlay.
