CityGML LOD1 Model Development and Disseminating Through Region Based OGC WFS Requests

Abstract

3D city model construction adopting OGC standards is the need of the hour for many countries. Research is heading towards effective methods for data collection for the 3D city model development process and disseminating all 3D city objects data of a specific user choice of region, through OGC web services. The current research work aims at building 3DCity LOD1 models using 2D geospatial data, disseminating the 3DCity objects information through OGC web services for a geographic region, building an ADE for modelling critical infrastructure such as electric lines, water pipes, etc., and modelling 2D critical infrastructure data in 3D CityGML model using the ADE. Models can be visualized using any CityGML visualizer like FME, Aristoteles, etc. The CityGML model is validated using OGC CityGML schema validator. Sample region based WFS results are shown along with the WFS performance test using a web services benchmark. CI ADE is validated through writing powerlines geospatial feature into CityGML model.
