10月7日的Geo Elevation: Path Analyzer应用程序分析

Draw a path and see its elevation profile. Draw an area and see the ground itself: its highest and lowest points, its slopes and contours, in 3D. Anywhere on Earth, with the numbers a planner needs. Paths that follow the trail. Add a few points and choose Walking, Cycling or Driving: each leg follows the real path or road. A second later the profile is there, one sample every 30 metres, with distance, climb and descent, average grade and the steepest hundred metres. Move along the chart and a ring on the map shows where you are. Areas that answer for the ground. Draw an area, a circle or a rectangle and Geo Elevation reads the ground inside it every 30 metres: lowest, highest and mean height, relief, mean and steepest slope, with the highest and lowest points marked on the map. Every path that crosses the area gets its own small profile; scrub along it and the ring follows on the map. Slope and contours. Colour steep ground the way avalanche maps do, from the angle you choose, and draw contour lines at a spacing that suits the relief. On the map, and on the ground in 3D. The ground in 3D. Turn the area, raise the heights, scrub a path and watch the marker climb. Print it on paper as you turned it, or save it as an STL file for a 3D printer. Layers, as in a drawing app. Many shapes in one document, each in its own colour; show, hide and reorder them. Undo and redo every step. Spot heights. Pick any point for the height of the ground there. In and out. Import GPX, KML and GeoJSON, and older Geo Elevation files. Export GPX with elevations, CSV, GeoJSON, an image or a PDF report. Quick Look shows a document's map and profile in the Finder and in Files. Your units, your map. Kilometres or miles, metres or feet, hectares or acres; each document remembers its own. Standard, satellite, hybrid and 3D map styles. Documents are plain GeoJSON, in iCloud Drive if you want them on every device. One purchase for iPhone, iPad, Mac and Apple Vision Pro. No account, no subscription. Elevation data comes from our own server, ASTER and Mapzen at 30 m, worldwide; the app needs an internet connection to fetch it. In English, German, French, Spanish and Japanese.
