Urban Geo Big Data

The geoportal of the URBAN GEO BIG DATA project hosts various use cases, including the processing of Land Use and Land Cover (LULC) datasets through Open Geospatial Consortium (OGC) Web Coverage Processing Service (WCPS). The datasets are land consumption maps from Italian Institute for Environmental Protection and Research (ISPRA) of 2012, 2015, 2016, and 2017; land cover map from ISPRA of 2012; GlobeLand30 of 2000 and 2010; and GHS (Global Human Settlement) built-up of 1975, 1990, 2000, and 2014. All the datasets have a spatial extent of Italy.

When a user clicks on a dataset of multiple years, WCPS returns the change of land use or land cover classes for the clicked coordinates. Besides executing processing for a set of coordinates, WCPS also calculates the amount of change of selected land use or land cover class for an area drawn by the user for two selected years. The geoportal can be accessed via http://urbangeobigdata.como.polimi.it/.
