Developing 3D real estate tax visualization / management system with GIS based procedural modelling approach

Abstract

Creating detailed 3D building models with independent sections presents some challenging obstacles, including the gathering and managing of massive 2D and 3D datasets. In order to solve the problems that arise during the evaluation and management of real estate taxation, it is necessary to investigate what kind of advantages 3D systems can offer. Most part of the datasets to be used are not available directly (e.g. architectural plan, building models etc.). It is aimed to develop methods for saving time and standardizing by providing automations in the process of making these data available. It is aimed to develop a feasible, cost-effective approach that balances performance and quality in the subject-specific 3D model production process. Rule-based modelling was preferred as a 3D modelling method. With this modelling approach, necessary coding has been made in CGA language for producing 3D models. Thus, 3D models can be produced automatically with independent sections regardless of the number of buildings. The relational database was transferred with City Engine, a procedural 3D modelling program, with CGA codes prepared. Afterwards, 2D geometries of buildings and building independent sections were arranged in GIS program and associated with attribute data including real estate tax parameters and other GIS attributes.
