LandXML encoding of mixed 2d and 3d survey plans with multi-level topology

Cadastral spatial units around the world range from simple 2D parcels to complex 3D collections of spaces, defined at levels of sophistication from textural descriptions to complete, rigorous mathematical descriptions based on measurements and coordinates. The most common spatial unit in a cadastral database is the 2D land parcel-the basic...

Mixed 2D and 3D Survey Plans with Topological Encoding

There is a wide range of spatial units in jurisdictions around the world, ranging from simple 2D parcels (spatial units defining 3D column of space) to complex 3D collections of spaces, which are defined at various levels of sophistication from textural descriptions to complete, rigorous mathematical descriptions based on measurements and...

A Conceptual Model Supporting a Range of 3D Parcel Representations Through all Stages: Data Capture, Transfer and Storage

Semantics-based Fusion for CityGML and 3D LandXML

For any developments that require spatial data, often the fusion of diverse spatial datasets is unavoidable. For instance in developing a 3D cadastral database serving various purposes, data may need to be sourced from different spatial datasets such as: building design models in BIM (Building Information Model) format, topographic and built...
