Abstract

The constant development of geo-sensors, the increasing computing power of most platforms and the continuous improvement of storage capacities contribute to the collection of an immense quantity of geodata worldwide. In the frame of the technical cooperation between the Federal Ministry for Economic Cooperation and Development (BMZ, Germany) and countries worldwide, the Federal Institute for Geosciences and Natural Resources (BGR, Germany), in cooperation with the partner countries and the German Society for International Cooperation (GIZ), develops workflows based on those data to respond to specific environmental challenges such as the management of natural resources or the impacts of climate change. In particular, spatial data of the Copernicus missions are of high relevance for our work. Beyond requirements and expectations similar to the INSPIRE data policy, specific challenges exist in the framework of the German international technical cooperation. The aim of this contribution is to highlight these challenges in the context of the international cooperation with countries worldwide, whilst giving some answers to how we cope and deal with these challenges to meet the projects goals on a daily basis and provide high quality standardized geospatial analysis, with the final goal of developing standardized and well transferable workflows. In line with the GEOSS strategy and as a representative example, we present the case of a project aiming at the fostering of sustainable ground water management in Maghreb. In this context, geospatial Copernicus data are used for multiple goals. First, RADAR data are used for determining surface deformation, in particular land subsidence due to an overexploitation of the aquifers for agricultural purposes. Second, additional multispectral and multitemporal data are used to determine agricultural land use and corresponding regional water consumption. One of the biggest challenge remains the acquisition, homogenization and standardization of in-situ geodata which would allow to validate and enhance the results. The choice of data and processing solutions in the frame of technical cooperation solutions are driven by the quite practical requirements, expectations and computing infrastructure as well as internet capacities of the partner countries. Online platforms and Open Source solutions are on particular interest for this task. At the end of the project, we expect the transfer of jointly gained knowledge in terms of standards and methods between the different involved countries and beyond.
