<p>An example implementation workflow using FWE ADE enriched CityGML LandUse dataset with SimStadt biomass workflow using <a href="https://www.safe.com/">Feature Manipulation Engine (FME)</a> can be represented as below.</p>
<p>Additionaly the CityGML FWE ADE can also act as a central data exchange format to connect different urban simulation tools. A use case diagram to exchange data from landuse simulator UD_InfraSim to an urban energy simulator SimStadt is represented as below. The purpose of this workflow is to simulate future biomass potential for a landuse scenario driven by population, climate and urban development changes in Vienna </p>

<p>As shown in the above diagram, as a first step, using FME software, CityGML LandUse dataset will be enriched with the required input parameters of surfaceArea, surfaceAreaUnit and vegetationCoverCategory available in the FWE ADE XSD (as defined in the parameters list under chapter B). surfaceAreas can be calculated using FME while vegetationCoverCateogry is custom codelist which is based on land cover satellite images. For the German case study of Landkreis Ludwigsburg, vegetationCoverCategory is derived from the 2016 national scale crop and land cover map of Germany based on imagery acquired by Sentinel-2A and Landsat-8 <a href="https://doi.pangaea.de/10.1594/PANGAEA.893195 ">(Griffiths et al., 2018)</a>. These input parameters are mandatory for calculating biomass potential from the CityGML LandUse datasets using SimStadt. The enriched CityGML LandUse is then inputted to the SimStadt biomass workflow. The output CityGML LandUse file with output parameters from the FWE ADE XSD will be directly added to the 3DCityDB which is already extended to store the FWE ADE parameters. From 3DCityDB, based on the user needs either the enriched CityGML LandUse file with biomass potential can be extracted or the enriched CityGML FWEArea/FWESystem file with biomass potential values can also be extracted. Below image shows an exemplary visualisation of the above process.</p>
