Open land-use map: a regional land-use mapping strategy for incorporating OpenStreetMap with earth observations

摘要: AbstractA land-use map at the regional scale is a heavy computation task yet critical to most landowners, researchers, and decision-makers, enabling them make informed decisions for varying objectives. There are two major difficulties in generating land classification maps scale: necessity of large data-sets training points expensive cost terms both money time. Volunteered Geographic Information opens new era mapping visualizing physical world by providing an open-access database valuable georeferenced information collected volunteer citizens. As one well-known VGI initiatives, OpenStreetMap (OSM), contributes not only road network distribution but also potential using these data justify delineate patterns. Whereas, large-scale approaches – including national scales confuse “land cover” “land-use”, or build up based on modeled la...
