The Groundwater Global App - global groundwater measurements with the smartphone

Make the invisible visible!

With Groundwater Global Foundation we offer a mobile app with public registration, which can be used by anyone.

Utilizing speaker and microphone, this mobile app turns anyone's smartphone into a groundwater measurement device.

The measurement is based on acoustic resonance and currently works down to thirty meters deep, providing large coverage world-wide.

Hand measurements such as these may be used as a first basis for groundwater management, or may complement fully automatic systems with the occasional calibration.

The mobile app works in internet connected regions, as all recordings are centrally collected in a single database in the cloud.

Recordings are analysed on a webserver, after which the groundwater depth is returned to the mobile app.

One unique aspect that this system has to offer is that it allows for citizens and water professionals to operate jointly.

Respecting privacy, citizens' measurements are private by default.

However, citizens can choose explicitly to unlock their locations, making them publicly visible and thereby turning themselves into citizen scientists.

Datasets are available for download from the database API (csv, xlsx, json) in a few different ways.

The system works with open data in the sense that everyone can download their own measurements.

Water professionals, including academic professionals, can download their own measurements from the API by project(s).

Interestingly, we provide the option that water professionals can download citizen science data by region, where they simply have to provide us with a shapefile for the region/area of interest.
