Example of datasets processed to demonstrate a multisource data integration methodology

This dataset contains the data processed to demonstrate the multi-source spatial data integration methodology proposed in the paper "Multisource spatial data integration for use cases applications".

It contains:

- the building footprint extracted from the IFC model of a newly designed building in WKT format, by using the GeoBIM_Tool (https://github.com/twut/GEOBIM_Tool);

- the extrusion of the footprint until the measured height measured with the same GeoBIM_Tool;

- a portion of the Rotterdam 3D city model generated with 3dfier and available at https://3d.bk.tudelft.nl/opendata/3dfier/, converted in CityJSON with the citygml-tools (https://www.cityjson.org/tutorials/conversion/), developed to convert data between CityGML and CityJSON.
