field data collection

QFIELD – mobile application for data collection established on the principles of open source software

Acquisition of primary spatial data (geodata) in the form of a field survey (i.e. direct contact of the surveyor with the observed object or phenomenon of the real world) can undoubtedly be described as the most demanding method of their acquisition in terms of time and financial costs. However, in the past ten years, there has been a sharp turnaround in the field of mobile mapping. With the introduction of smartphones and laptops (tablets), countless applications for field data collection have been developed. Combined with Open Source tools, mobile data collection activities have become widely available to both professionals as well as the general public. One of these applications is QField. It is a multi-platform mobile GIS designed primarily for Google Android, Apple iOS, and Microsoft Windows platforms. Its user interface is strikingly similar to that of the QGIS desktop app, giving the false impression that the mobile app is part of it. However, it is stand-alone software developed by an Open Source solutions group, OPENGIS.ch, whose compatibility with the desktop application is ensured by another element, a plugin.
