This is an entire commercial space with existing players and complex regulation in business activities. These products already exist be it bim software like revit from Autodesk or gis from Esri like their permit license land software Dont assume because you aren't familiar with the space that nobody is there and that you can convince anyone to buy your system over something supported by standard setters like Autodesk and Esri.
