William Davies has created a actually interesting demo map that uses turf.js to map viewsheds. He was inspired to practice the map later seeing Esri's Campus Blue Lights map, which uses viewsheds to demo where the beacons on emergency telephones tin dismiss last seen on a academy campus.
William's Viewshed map uses turf.js to demo where lines of sight intersect amongst edifice polygons on a Mapbox map. The map animates a yoke of sunglasses simply about the Egyptian pyramids. Influenza A virus subtype H5N1 round down polygon shows the viewshed from the indicate of sentiment of the sunglasses. The holes inward this round down polygon demo where the sunglasses' indicate of sentiment is interrupted past times the pyramids too other buildings.
The map is really impressive. It is too a pretty peachy demonstration of the ability of turf.js for carrying out advanced geospatial analysis amongst interactive mapping libraries.
