AQUARIUS – Where Smart Water Data Meets the SMART Tunnel

There has been a lot of talk recently about the difference between “smart data” and big data. Big data involves collecting copious amounts of information; smart data involves processing the data collected to create actionable data that empowers decisions.

Hydrometric Grammar – Is Data Singular? Are Datum Plural?

Good stream hydrography requires careful attention to technical detail. We care deeply about the precision of our data. So why would we be tolerant in the precision with which we define data?

The OGC WaterML 2.0 standard is an industry game-changer. Now it is easier for hydrometric data producers to make their data accessible for timely decision making and it is easier for data consumers to find relevant data to drive evidence-based decision making. Almost as important as the sharing of data is the sharing of data quality. Let me explain. There are a great many, perfectly valid, ways of measuring almost anything. However, the quality of the different measurements of the same thing will vary as a result of a wide variety of factors. As a thought experiment, imagine you are … Read More
