Write a python code for Ifc to CityGML/CityJSON conversion using Web Semantics
Budget $10-150 USD
Job Description:
IFC, construction architecture etc. is a structure description data type used in applications, while CityGML focuses more on geographic details and describes both structures and their geographic relationship to other structures. This data is based on IFC Express and encoded with XML. CityGML, on the other hand, is GML-based, that is, it contains geographical definitions. However, IFC may also contain geographic coordinates. As for the conversion part, I want to convert a data I have from ifc to citygml using Python. But this needs to be done using semantic web. For this, first of all, IFC data should be defined ontologically and then logical mappings should be made between IFC-CityGML data. After that, the conversion process needs to be done based on these mappings. During all these processes, there should be no loss of geometric and semantic information in the data. Since these two data types can be visualized as 3D models, I need to be able to visualize the transformed data at the end of the process. You need to do this with using semantic web. And I need all the codes and the converted data too. The final citygml data must be without data loss and georeferenced. Here is the source websites:
IFC: [login to view URL]
CityGML: [login to view URL]
In summary I mean that I need the parse Ifc file and save as an RDF triple. After that I need to map these IFC/RDF data and citygml semantically and do a geometric conversion for georeferencing. And after all these I need to write the mapped data as an citygml file format
