Light Pollution Map vs Directional Camera

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)

Your iPhone saves the GPS location with every photo—telling you where you stood. But it doesn't tell you which direction the camera was facing, or the angular size of what you saw. Directional Camera fills that gap. It transforms your device into a survey-grade instrument, burning critical orientation data directly into the image for permanent documentation. BUILT FOR PROFESSIONALS Whether you are a scientist documenting field phenomena, an engineer on a construction site, or an investigator gathering evidence, precise data matters. Directional Camera provides the context that standard metadata leaves out. KEY CAPABILITIES Precise Orientation: Instantly visualize the camera's Azimuth (Compass Direction) and Pitch (Elevation Angle) relative to the horizon. Angular Measurement Grid: Use the overlay grid to estimate the real-world angular size and scale of distant objects. Data-Rich Overlay: Every photo includes a stamped footer with timestamp, GPS coordinates, altitude (MSL), and orientation data, ready for reports and archives. IDEAL FOR: Field Research: Document weather patterns, geological formations, and biological surveys. Construction & Engineering: Verify site alignment and document progress with directional context. Forensics & Investigation: Capture evidence with irrefutable orientation data. Site Scouting: Plan solar installations or architectural framing by tracking sun position and viewing angles. Stop guessing what you were looking at. Capture the full picture with Directional Camera.
