In the last project year, one major focus is on the demonstration and evaluation of the LOKI framework together with end users.
In the last project year, one major focus is on the demonstration and evaluation of the LOKI framework together with end users.
In this context, THW Heidelberg tested the modules of [UAV mission planning](https://git.gfz-potsdam.de/loki/loki_wiki/-/wikis/Project-Results:-UAV-Mission-Planning) and [automatic damage classification](../project_results/automatic_damage_clf.html) modules, as part of the [LOKI framework](https://git.gfz-potsdam.de/loki/loki_wiki/-/wikis/LOKI-Framework). Following a live demo of the two modules, we jointly discussed current functionalities and how the modules might be integrated in workflows of THW Heidelberg.

We also collected valuable feedback on how to further improve the modules so they meet requirements of THW in case of an earthquake event.

Furthermore, we presented the [modular structure](https://git.gfz-potsdam.de/loki/loki_wiki/-/wikis/LOKI-Framework) of the LOKI framework, which allows using modules as stand-alone applications and [combining them](https://git.gfz-potsdam.de/loki/loki_wiki/-/wikis/Framework-interfaces) for a specific use case.

[HELIOS++](https://www.geog.uni-heidelberg.de/gis/helios.html) is a general-purpose simulation software for virtual laser scanning data acquisition. Such data can be used to complement real data in many use cases. Some examples include the generation of training data for machine learning, especially deep learning, for the validation of algorithms working on point clouds, for acquisition parameter surveys or for experimentation with novel sensors.

The completeness mapping tool enables to assess the completeness of OSM building footprints. It is already tested and validated via a dataset provided by experts. It is included as a project into the [Map Swipe App](https://mapswipe.org/en/index.html).
As part of the [crowdsourcing tool](https://git.gfz-potsdam.de/loki/loki_wiki/-/wikis/Project-Results:-Crowdsourcing), the completeness mapping tool enables to assess the completeness of OSM building footprints. It is already tested and validated via a dataset provided by experts. It is included as a project into the [Map Swipe App](https://mapswipe.org/en/index.html).
Colleagues from [GIScience](https://www.geog.uni-heidelberg.de/gis/index.html) and [3DGeo](https://www.geog.uni-heidelberg.de/3dgeo/index.html) research groups and [HeiGIT](https://heigit.org/) tested the tool and evaluated the completeness during a mapping event in September 2020. The study sides were Medellin (Colombia), Siros (Greece), Tokyo (Japan) and Taipeh (Taiwan). Information about this event was also shared on the [GIScience News Blog](http://k1z.blog.uni-heidelberg.de/2020/09/16/osm-completeness-mapping-for-airborne-situation-assessment-following-an-earthquake/).
