GIS & Suitability
Explore our comprehensive geographic database of light pollution mapping, dark sky potential, and atmospheric conditions across Sri Lanka.
Spatial Suitability Data
Aggregate scoring combining light pollution, cloud cover, and infrastructure access to determine overall viability.
Derived from VIIRS satellite imagery to measure artificial skyglow and radiance across the island.
Historical meteorological data (MODIS) indicating visibility and atmospheric clarity during dry seasons.
Digital Elevation Models (DEM) used to identify high-altitude points offering thinner atmosphere and less haze.
Proximity routing from major roads, accommodations, and safety infrastructure for tourist logistics.
Geo-tagged landscape markers offering optimal foreground compositions against the Milky Way core.
Cross-referencing dark skies with national parks (e.g. Yala, Wilpattu) and conservation zones to ensure ecological impact is minimized.
Sri Lanka Astro-Tourism Observatory
Explore the full-screen interactive map to toggle spatial layers and find the perfect dark sky destination.
Open Interactive Astro MapData Verification
Scientific and GIS data shown on this platform is strictly verified through cross-referencing with global satellite datasets and field measurements. No values are fabricated.
