Land surface morphology information, such as vegetation and buildings, are key inputs for the parameterizations used in the Three-dimensional Wind Field 3DWF. The microscale land morphology data are often not available andor are not in a format that 3DWF can readily use. We have developed a novel method to create the land morphology data set and rasterize it to the model grid using Google Maps and the accompanying application programming interface API. This report documents the algorithm, the development of a graphical user interface GUI prototype, the process of rasterizing morphological features for a given model domain and terrain map, and step by step procedures for producing necessary input data for the 3DWF model.
