From the 80s, while the climate changes issue starts to rise interest, due to financial constraints and the advent of satellite era, monitoring networks begin to decline [1]. Remote sensing with its capability of global monitoring put on a side the direct observation that often requires high investments at local level for installation and maintenance. Nevertheless in-situ monitoring is essential for a large number of actions that requires continuous, long-term, high-frequency, and accurate data as well as to calibrate and validate remote sensing data. With the advent of IoT in situ monitoring is getting back the necessary attention and more people, also in the field of FOSS4G, are starting to work in this field.
The IstSOS development team is working since the 2009 to bring in-situ monitoring back to the golden ages fostering the interoperability and the data management best practices. Several projects are here presented to demonstrate how istSOS, IoT and openness can contribute to this goal through a number of applications in the fields of agriculture (ENORASIS), water management (hydromMetTI, FREEWAT, TRESA), risk mitigation (SITGAP, MIARIA), health (ALBIS), development and cooperation (4ONSE).

During the last years, a Borehole Data Management System (BDMS) has been developed by the Federal Office of Topography of Switzerland (Swisstopo). To facilitate the data exchange procedure, a standalone application built with closed source software is used, but this approach starts to feels too hard working by the users and recently an increasing number of partners start asking for a web-based solution. To fulfill this demand, we developed a new Web Application Prototype, sponsored by Swisstopo, using the latest Free and Open Source Technologies. The new application integrates some of the today’s best OSGeo projects and will be available (summer 2019) as a modular open source solution on GitHub and ready to use in a docker container available on Docker Hub. Through two types of authorization, Explorer users are able to search the BDMS for specific boreholes, navigate a configurable user friendly map, apply filters, explore the stratigraphy layers of each borehole and export all the data in Shapefiles, CSV or PDF. Editors are able to manage in details the informations and publish the results after passing a validation process.
