crosstech-core-coordinate-systems

Use when transforming coordinates between BIM local systems and GIS global systems, handling CRS conversions, or debugging models appearing at wrong locations. Prevents the common mistake of applying wrong EPSG codes, ignoring axis conventions (Y-up vs Z-up), or losing precision in coordinate transformations. Covers IfcMapConversion, IfcProjectedCRS, EPSG codes, pyproj/PROJ transformations, and axis conventions for Blender, Three.js, QGIS, Revit, FreeCAD, and IFC. Keywords: CRS, EPSG, coordinate system, georeferencing, IfcMapConversion, IfcProjectedCRS, pyproj, PROJ, Y-up, Z-up, BIM to GIS, map conversion, model at wrong location, coordinate transform, which EPSG code.
