Walkshed.js: Client-side Raster Processing with OSM Data Tiles – Aaron Ogle
OSM is commonly used for map tile generation and routing, but much less so with data rasters. Rasterizing OSM data can open up a whole new set of mapping and analytical possibilities using map algebra. Walkshed.js is a project combining OSM data tiles and cost-distance raster calculations to measure pedestrian access for a location. This talk will be a technical dive into creating OSM data tiles and the JavaScript code used to do raster processing in the browser.
