A new version 2.0 of the GEUS developed field app for geologic sample collection in Greenland was released by GEUS’ Geological Data Centre recently. The app is based on ArcGIS Field Maps and it is capable of going offline with GPS tracking in remote areas. It has various basemaps, such as geological and topographic maps, and satellite images sideloaded onto the field device.

The app can track the location of each geologist and mark their GPS position on a map along with the location of all their sample collections and structural measurements. Through a simplified formular, the geologist can specify their type of sample and use various interactive options to narrow down their description. In total, the app has 39 code lists with over 800 coded values, some combined into contingent values. The geological information is based on GEUS’ stratigraphic database and other various international databases. The app can attach various data files such as memos, audio files, videos and field photos taken with the field app to each location.
When the geologist return, the app can sync all the collected samples, locations and structural measurements along with the attachments to the GEUS ArcGIS infrastructure. From here, the geologist can instantly access all combined field data either online or through their ArcGIS Pro workstation. Besides that, the geologist can also access a web app with a dashboard that shows the statistics of all the collected field data, such as when the sample was collected, by whom, for what purpose and so on.

The app has also been shared with Mineral Resources Authority in Greenland for their field work.
