Visibility analysis (for visual impact assessments), spatial SQL (basic stuff only). That sort of thing.spoedniekhttp://www.blogger.com/profile/13272734221796825089noreply@blogger.comBlogger21100tag:blogger.com,1999:blog-6340812.post-10092214199700676682010-05-27T10:42:00.000+02:002010-05-27T10:46:24.060+02:00

Visual Exposure: Alternative Approach Cumulative Visibility First, a cumulative viewshed is created in TNTmips. A viewshed for each turbine is created at 10m height intervals (up to the tip of the rotor as a worst case scenario). These are then added together using a raster function (I have to use TNTmips since it's impractical to do it in Manifold using vector data structures). I then import

Visual ExposureVisual exposure is based on distance from the project to selected viewpoints. Exposure or visual impact tends to diminish exponentially with distance. - Oberholzer 2005I think this is at least one way of indicating the distance effect (see first image - it's not the best example but it does give one an idea?). I created buffers around the development site point (100m, 250m, 500m,
