Abstract:
Monitoring urban expansion is important because the policy makers in cities must detect the changes to provide services and manage resources for urban dwellers. In this study we analyse the built-up areas extracted from very high-resolution images of two important databases of CORINE land cover and GHSL; Built-Up Grid to map urban expansion at local level of cities of Tallinn and Tartu in their context (County) in Estonia. The reason for selecting these datasets was the representation of an available temporal data in many timespans which allowed extracting urban expansion in our case studies. The analysis was carried out over a subset of these datasets in ArcGIS environment and the data of GHSL-Built-Up Grid was extracted from Google Earth Engine platform. Therefore, the results showed that there was an increase in the amounts of built-up areas and its rate in these two counties while based on these two databases the results were not similar in areas and cells but similar in rate and
growth patterns.
