The evolution of WebGL together with vector map tiles has led to around interesting experiments inward visualizing tiptop together with depth information on interactive maps. For example this calendar week nosotros saw a couplet of creative mapped visualizations of bathymetry together with Lidar data.
Contours.org has used historical depth information of Scotland's lochs to practice a serial of 3d WebGL maps of iv of Scotland's biggest lakes, including Loch Ness.
The depths of most of Scotland's lochs were non measured until the mid-Nineteenth Century. The get-go existent systematic survey of the lochs was started inward 1897 yesteryear the oceanographer Sir John Murray. From 1897 to 1909 Murray carried out 60,000 soundings together with produced the get-go e'er detailed charts, amongst depth data, of Scotland's major lochs.
Contours.org has digitized the bathymetry information from Murray's survey for iv of Scotland's lochs together with created 3d bathymetry maps. These maps allow you lot to explore the bathymetry contours of Loch Ness, Loch Lomond, Loch Levan together with Loch Morar inward 3d. Contours.org also allows you lot to stance the bathymetry contours of each loch inward sec overlaid on an aerial map.
The Cartographic together with Geological Institute of Catalunya has developed a paradigm terrain explorer for their two meter Digital Elevation Model of Catalonia. The Institute's Relief together with Shadow map, created from Lidar data, uses vector map tiles to allow you lot to interact inward real-time amongst a relief map of the area.
Using Relief together with Shadow you lot tin explore the DEM model of Catalonia inward an interactive Leaflet & Mapzen powered map. The map includes an impressive tool which allows you lot to color the terrain yesteryear tiptop together with yesteryear the management of the sun. This tool allows you lot to alter the appearance of the map inward real-time yesteryear icon inside an interactive reach rose.
Using the color-picker tool amongst the interactive reach rose you lot tin pigment the terrain on the map to highlight unlike tiptop information together with unlike directions of light. The pump of the reach rose represents lower elevations on the map together with the elevations croak higher equally you lot movement out towards the circumference.
Relief together with Shadow is partly based on Mapzen's Sphere Map Demo. You tin acquire to a greater extent than nearly how Mapzen developed their 'sphere maps' tool on this Mapzen Sphere Maps spider web log post.
The recent add-on of to map 3d buildings. Next calendar week on nosotros volition await at how this extrude belongings tin also travel used amongst Lidar information to practice 3d visualizations of tiptop data.
