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.本数据集包含经处理后的数据，用于演示论文《Multisource spatial data integration for use cases applications》中提出的多源空间数据集成方法论。数据集具体内容如下： - 采用GeoBIM_Tool（https://github.com/twut/GEOBIM_Tool）从某新建建筑的IFC模型中提取的、以WKT格式存储的建筑基底轮廓（building footprint）； - 利用同一GeoBIM_Tool获取的实测建筑高度，对上述基底轮廓进行垂直拉伸得到的三维模型体块； - 由3dfier生成的部分鹿特丹3D城市模型，该数据集可从https://3d.bk.tudelft.nl/opendata/3dfier/获取，并通过专为实现CityGML与CityJSON格式数据互转而开发的citygml-tools（https://www.cityjson.org/tutorials/conversion/）转换为CityJSON格式。
