The here presented Virtual Campus project developed a 3D geodata modelling toolchain, and an open source software based technology stack for creating a Digital geoTwin of the University of Cologne (UoC). We also develop and present a reactjs based web application, a flutter and Unity based mobile app with AR features, as well as an UnrealEngine based VR application to access, browse and visualize the geoTwin data and models in the UoC CAVE 3D environment. The 3D models of the Universities Buildings will include indoor models based on 2D floorplans, which will facilitate indoor positioning in the mobile application of the project through geometry matching and simultaneous localization and mapping (SLAM) technology. For distribution and streaming the 3D building models, we utilze the OGC Standard 3D Tiles, for which we present a tool to georeference the glTF 3D models and assets accurately on the globe.

This contribution describes the development of a plugin for the geographic information system QGIS to interface the openModeller software package. The aim is to use openModeller to generate species' potential distribution models for various archaeological applications (site catchment analysis, for example). Since the usage of openModeller's command-line interface and configuration files can be a bit inconvenient, an extension of the QGIS user interface to handle these tasks, in combination with the management of the geographic data, was required. The implementation was realized in Python using PyQGIS and PyQT. The plugin, in combination with QGIS, handles the tasks of managing geographical data, data conversion, generation of configuration files required by openModeller and compilation of a project folder. The plugin proved to be very helpful with the task of compiling project datasets and configuration files for multiple instances of species occurrence datasets and the overall handling of openModeller. In addition, the plugin is easily extensible to take potential new requirements into account in the future. [ABSTRACT FROM AUTHOR]
