Urban form or morphology is a valuable multidimensional variable to consider in climate-sensitive-planning because it significantly drives the micro-scale climatic variability in cities. Yet techniques to classify urban forms are heavily dependent on the availability of the detail urban geometry data. A common data source is high resolution remotely sensed images (RSI), which can provide information at large spatial scales. But this information is usually not available in low-income rapidly growing cities, where it is most needed.The RSI data available in these places are often patchy, well out of date and cannot reflect the radical development until it is too late for public policy interventions. Maps from Scraps brings an innovative solution of generating high definition maps from patchy data.
