Later I wrote a stylized map output that I then reused here.Īlso take a look at mapgen4, my newer map generator that allows painting your own mountains, valleys, and oceans. Back in 2010 I wrote an article about the algorithms the original demo was in Flash. The generator intentionally makes unrealistic terrain that was designed for the needs of our game, Realm of the Mad God. You can right-click on the map to save a higher resolution image, or click the share link to save all the current parameters in a URL. Can you find an ice lake? They’re rare at the default temperature. Try clicking on the Seed input box and hold down the Up arrow key to quickly scan many different island shapes. The simplest way to explore the maps is to click the plus/minus arrows to change the Seed.
To recommend an elevation data source, mention it in your request.This map generator creates volcanic island style maps. If you notice an area where elevation data needs improvement or updates for any reason, contact our raster imagery team at Elevation data is not improved on a set schedule and is updated when and where it becomes available. You will likely need to parse the returned GeoJSON to find the highest elevation value. In the Mapbox Terrain tileset, contours are comprised of stacked polygons, which means most of your requests will return multiple features from the contour layer. When working with the returned data, consider these factors:īecause the elevation data you want is included in the contour layer, you will need to parse the returned GeoJSON to isolate the features from the contour layer. To request a raster tile, use this Raster Tiles API endpoint: Get elevation To access elevation data encoded in Terrain-RGB tiles like those contained in the Mapbox Terrain-RGB and Mapbox Terrain-DEM tilesets, you can use the Raster Tiles API. const coordinate = const elevation = map. If you are using Mapbox GL JS to build a web application, you can use queryTerrainElevation to access data in the map. This guide describes advantages and disadvantages of each tileset, and explains how you can access the elevation data in these tilesets. Mapbox Terrain contains features with an ele property for elevation values.Mapbox Terrain-RGB and Mapbox Terrain-DEM contain elevation data in Terrain-RGB tiles.Several Mapbox tilesets contain elevation data: Such data can be used to create a Digital Elevation Model (DEM), which is a representation of the topographic surface of the Earth.
Elevation data are elevation measurements for locations distributed over the land surface.
