The evolution of WebGL as well as vector map tiles has led to roughly interesting experiments inwards visualizing superlative as well as depth information on interactive maps. For representative this calendar week nosotros saw a distich of creative mapped visualizations of bathymetry as well as Lidar data.
Contours.org has used historical depth information of Scotland's lochs to exercise a serial of 3d WebGL maps of 4 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 kickoff existent systematic survey of the lochs was started inwards 1897 yesteryear the oceanographer Sir John Murray. From 1897 to 1909 Murray carried out 60,000 soundings as well as produced the kickoff e'er detailed charts, alongside depth data, of Scotland's major lochs.
Contours.org has digitized the bathymetry information from Murray's survey for 4 of Scotland's lochs as well as created 3d bathymetry maps. These maps allow yous to explore the bathymetry contours of Loch Ness, Loch Lomond, Loch Levan as well as Loch Morar inwards 3d. Contours.org also allows yous to persuasion the bathymetry contours of each loch inwards sec overlaid on an aerial map.
The Cartographic as well as Geological Institute of Catalunya has developed a epitome terrain explorer for their ii meter Digital Elevation Model of Catalonia. The Institute's Relief as well as Shadow map, created from Lidar data, uses vector map tiles to allow yous to interact inwards real-time alongside a relief map of the area.
Using Relief as well as Shadow yous tin explore the DEM model of Catalonia inwards an interactive Leaflet & Mapzen powered map. The map includes an impressive tool which allows yous to color the terrain yesteryear superlative as well as yesteryear the management of the sun. This tool allows yous to alter the appearance of the map inwards real-time yesteryear icon inside an interactive ambit rose.
Using the color-picker tool alongside the interactive ambit rose yous tin pigment the terrain on the map to highlight unlike superlative information as well as unlike directions of light. The see of the ambit rose represents lower elevations on the map as well as the elevations choke higher every bit yous motility out towards the circumference.
Relief as well as Shadow is partly based on Mapzen's Sphere Map Demo. You tin acquire to a greater extent than most how Mapzen developed their 'sphere maps' tool on this Mapzen Sphere Maps weblog post.
The recent improver of to map 3d buildings. Next calendar week on nosotros volition await at how this extrude holding tin also hold upward used alongside Lidar information to exercise 3d visualizations of superlative data.
