Abstract

Google Earth Engine is a cloud computing platform for developing and hosting web applications that allows for the automatic sorting and mapping of terrestrial coverage. The objective this research is to evaluate the tool's potential for the generation of thematic maps of urban areas, using a big data plataform, with data in the cloud. The proposed methodology evaluate the CART classifier for different scales. The local scale considered the area of Rio de Janeiro city. A simplified legend (urban and non-urban) and other with greater detailing (different types of urban intensify), were tested. The main input was the Landsat TOA (Top of Atmosphere) mosaic. Potential, classification time, and results were evaluated. The main products generated were the temporal classifications, in which one can observe the expansion of urban areas and some confusion between classes. In this case editing is necessary. The rapidity in the classification and generation of products is one of the most important positive points of the analysis. The tool is very interactive and easy to handle, even by users with little experience. The urban areas delimitation and identification were promising, requiring more research on the best techniques to be adopted at each geographic scale.
