EGT-TWINN Project is for the Geological Survey of Estonia all about cooperation with other geological surveys and learning from each other. Many interesting seminars and workshops have already taken place during the first 8 months of the Project and numerous are yet to come. This time our staff visited Danish colleagues at the GEUS Aarhus Office to cover a wide range of topics from data collection in the field to complex 3D modelling solutions and applications. The field trip offered a comprehensive view of Denmark's complex Quaternary sedimentary structures and processes.
As EGT plans to include more 3D modelling in its projects and workflows, it was incredibly useful to learn what data specialists in GEUS use, how they prepare it for the modelling process and how they build their 3D geological models. It was also very interesting to learn how to derive more insights into deeper geology from detailed digital elevation models, which might be underutilised in EGT. As EGT currently lacks any meaningful geophysical capabilities, it was good to learn about and try out several geophysical methods currently used by GEUS. The t-TEM method is certainly something we must consider, as it seems capable of collecting a significant amount of high-quality data in a relatively short time in relatively similar geological conditions.
Although GEUS’ capabilities and achievements are enviable, we were happy to learn that there are topics where EGT has advanced somewhat further and could share its experience with GEUS. For example, having integrated different ArcGIS solutions in its workflows, EGT’s fieldworkers have a user-friendly app for collecting data points in the field. All the collected data are stored in a database. Some GEUS fieldworkers still depend on making notes on paper, although some QGIS solutions are also partially in use. However, the data collected in the field are not stored in a centralised database.
Besides learning about different technical solutions, at least equally valuable was the establishment of new connections between the specialists from two very similar organisations. We are sure there will be further cooperation even after the culmination of the current EGT-TWINN project.
