Questions & Answers

As answered by people managing Hilldar.
  1. What makes Hilldar unique?

    Hilldar draws the skyline you actually see, and keeps distant mountains true to shape even 250 km away, with Earth’s curvature and refraction included. Peaks, towns and castles get their names, and the sun, moon and stars appear for any date and hour. Your own photo fits onto the ridges, so the peaks in it get named too.

  2. Why should a person choose Hilldar over its competitors?

    You can check it: lay your photo over the panorama and watch the distant ridges line up. Terrain and sky share one view, so you see which ridge the moon will rise over. The core is free and a shared link opens the exact same view for anyone.

  3. How would you describe the primary audience of Hilldar?

    Anyone on a hilltop wondering what they’re looking at: hikers, lookout-tower climbers, families on a walk. Then the planners: landscape and astro photographers, long-view hunters waiting for the Alps to show, and travellers checking a view before the trip.

  4. What's the story behind Hilldar?

    On every Czech hilltop the same two questions come up: what’s that hill in the distance? Hilldar was built to answer, and the hard part was distance: a mountain 200 km away has to keep its true outline for the answer to mean anything. So Hilldar computes the curve of the Earth and the bending of light, then lets your own photo prove it.

  5. Which are the primary technologies used for building Hilldar?

    WebGL 2 and three.js in the browser, with custom shaders for terrain, ink lines, atmosphere and clouds. Data comes from Mapterhorn elevation tiles, OpenStreetMap, Wikidata, Copernicus Sentinel-2 and astronomy-engine.

  6. Who are some of the biggest customers of Hilldar?

    • Hikers and lookout-tower visitors
    • Landscape and astrophotographers
    • Long-distance view hunters

    The customer answer still lists user groups, because Hilldar has no corporate customers to name.

    Hilldar names every hill you can see from any spot, even peaks more than 200 km away. Stand on Rigi and the Swiss Alps fill the horizon with hundreds of ridges stacked behind each other. Hilldar draws each outline so precisely, more precisely than any other app, that you can tell which jagged edge is the Eiger and which is the Jungfrau. Upload a photo from a hike and it lines up the horizon and labels the peaks. It also shows when the sun and moon rise from behind the ridges, all in the browser.
