![]() Then, open the plugin window ( Plugins => Manage and Install Plugins) and find the CityJSON Loader. You can download and install the latest version of QGIS from here. Then you can convert your CityGML data with this command: $ citygml-tools to-cityjson /path/to/your/CityGML.gml Loading CityJSON in QGIS Install QGIS and the CityJSON Loader plugin. It is a command-line utility that bundles several operations for processing CityGML files. This will also be the name of the folder containing all the plugin files. The Class name will be the name of the Python Class containing the logic of the plugin. You can fill the form with details relating to our plugin. You will see the QGIS Plugin Builder dialog with a form. From CityGML => To CityJSONĪny CityGML datasets can be converted to the CityJSON format using the citygml-tools. Go to Plugins Plugin Builder Plugin Builder. You can check out this article to check out the available open-source CityGML datasets. ![]() For this reason, the CityJSON has been developing as an easy‐to‐use JavaScript Object Notation (JSON) encoding for 3D city models using the CityGML 2.0 data model. However, it is based on GML encoding which has a complex nature and poor interoperability. One of the most popular data schemas for the 3D city models is the OGC CityGML which is a global data model for describing 3D geo-spatially-enabled urban models developed by the OGC (open geospatial consortium). In the world of 3D data, the 3D city models have been used for many application domains such as 3D cadastres, facilities management, and emergency response. This article will introduce the use of this plugin for loading the CityJSON 3D city models with some examples. ![]() Accordingly, it is possible to visualize the building models at a higher Level of Details. In 2020, the QGIS plugin for loading CityJSON 3D city models in QGIS has been developed. This will result in the Level of Details-1. However, the usual way the building- or city models had been visualized in the 3D GIS projects is by extruding the building footprints. It’s called the 3D map view and is accessed from the View context menu. Since version 3.0 of the QGIS, a separate interface is responsible for 3D data visualization of the Point cloud and Digital Elevation Models. ![]() QGIS is one of the most popular free and open-source cross-platform desktop GIS application software that every GIS geek knows. The Web App Builder plugin for QGIS allows for the creation of web applications based on layers as configured in QGIS. In Geospatial Data Science, the 3D data models recently play an important role in the research and visualization projects.
