Use Cases

Use cases show how we are facilitating a new means by which geoscience experiments are carried out by showing how traditional experiments would have missed events of interest due to a lack of access to real-time data.

Basic form: As a ____ I want to _____ so that _____

(use cases -> requirements -> deliverables)

---

As a researcher, I want to create a real-time networked data distribution system, without writing complex software, purchasing any hardware, downloading and installing software, or employing specialized software engineering and IT staff.

As a CZO scientist, I want to assimilate real-time data into spatially distributed models and visualizations.

As a shipboard scientist, I want early career scientists to be able to participate remotely in my research to collect data samples so that the expedition is more efficient and to lower the barrier for early career scientists to undertake sea-going research by allowing for smaller projects to be funded and completed prior to pursuing larger expedition funding.

As a geoscience educator, I want access to real-time data in the classroom in order to enable the next generation of interactive educational and outreach activities.

As a structural geologist, I want real-time access to field data in order to enable the seamless interaction with existing workflows and data sources.

As a scientist, I want to focus on analysis tasks rather than data handling technology.

As a science team, we want to be able to set up a CHORDS portal instance completely by ourselves (without help)

As a science team, we want to be able to continue supporting their existing connections to their current user community while at the same time taking advantage of the CHORDS framework.

As an end-user, I want to use the CHORDS portal template to create a new server, login, define what instruments will be streaming in data and where those instruments are located, configures what variables are being measured, and write a few lines of code to send data points via URLs

As an emergency manager, I want real-time data aggregation, visualization and download functionality to integrate radar data (time series and scan data) and derived products, coupled in real-time, to enable the creation of a holistic water instrument and real-time warning and support tool that assimilates the data into actionable models to provide real-time rainfall rate and accumulation, detection of tornadoes, and location of hail, as well as short-term forecasting of these phenomena so that I can effectively respond to hazardous weather phenomena including flash floods, high winds, tornados, and hail.

As a techtonophysics researcher, I want real-time access to geodesy, seismic and atmospheric sensors deployed near a volcano in Tanzania, so that I can detect transient events and disseminate warnings through a hazard alert system to the local community.

As a researcher deploying cheap ($200-$300), disposable 3-D printed surface-met weather stations across the globe (so far in Colorado, Maryland, Zambia, Kenya) run with Raspberry Pi’s, I want to communicate with my weather stations and visualize the data so I can remotely monitor the stations are respond to problems detected, and handle queued data when my remote network connectivity goes down.
