DESCRIPTION:Beneath our feet lies one of the least explored environments on
  Earth. While mountains\, rivers\, and landscapes are well mapped\, the su
 bsurface remains largely hidden. Digital soil field data collection offers
  an efficient way to shed light on this unseen world. This is particularly
  important because protecting high-quality soils requires knowing where th
 ey are. Despite its importance\, only about 13% of agriculturally used soi
 ls in Switzerland are covered by detailed soil information\, and mapping h
 as traditionally been carried out on paper.\n\nGeodata applications now en
 able direct digital data collection in the field. In search of an open-sou
 rce solution\, I developed a QField project for practical soil mapping. QF
 ield is a powerful mobile app based on QGIS that enables efficient field d
 ata collection. This presentation outlines design considerations from the 
 development process built on continuous feedback from field workers.\n\nTh
 e overall system architecture is defined by QField\, but key decisions suc
 h as deployment (local or remote) and data management still need to be des
 igned carefully. The identified best practices will be compared in terms o
 f usability\, collaboration\, and technical complexity. An important consi
 deration is the choice between local and cloud-based setups\, as this affe
 cts the optimal project size as well as the handling of databases and laye
 rs. For editing layers\, either GeoPackages or PostgreSQL can be used. Reg
 arding background layers\, it is important to distinguish between online W
 eb Map Service (WMS) and offline raster datasets in order to keep the proj
 ect lightweight.\n\nOther key design considerations presented include clos
 ely replicating paper-based workflows in a digital environment\, ensuring 
 near real-time performance\, and maintaining a clear overview despite the 
 limited screen size of mobile devices.\n\nIn conclusion\, careful QGIS pro
 ject preparation has enabled efficient\, robust\, and practical digital so
 il data collection with QField. A major benefit is that observations are n
 ow collected and stored digitally. The captured information is no longer i
 n heterogeneous handwritten field notes but instead provides structured da
 ta and accessible knowledge. The presented best practices can serve as ins
 piration for other QGIS users aiming to improve the efficiency and usabili
 ty of their own QField mobile app projects.
