UK: Computer modelling is being employed to map walking routes around Britain’s cities for website www.walkit.com. Using accurate terrain data captured from the air, the height models from aerial mapping company Bluesky are being used to produce walking routes that avoid the steepest hills and alert walkers to inclines on their selected journey, information that is especially useful for those carrying loads, pushing buggies and those with certain health conditions.
“By supplementing our routes with information derived from the Bluesky height models we can really boost our offering,” said Jamie Wallace, walkit.com’s founder. “We already enhance traditional mapping with footpath data derived from high resolution aerial photography and user feedback, and the inclusion of incline data will further enable visitors to the site to select the most appropriate route for their needs.”
The height data walkit.com purchased from Bluesky is part of the GeoPerspectives nationwide Digital Terrain Model (DTM). Covering the whole of England, Scotland and Wales the DTM maps the Earth’s surface, excluding vegetation and buildings, to a resolution of 1 metre and an accuracy of 50 centimetres for urban areas with a population over 100,000. GeoPerspectives is a joint venture between Bluesky and Infoterra providing national coverage of orthorectified aerial photography, digital terrain & surface models and colour infra-red imagery (CIR).
