Geospatial Round-up – April/May 2018

Galaxy mapped in 3D ESA’s Gaia mission has produced a very detailed star catalogue, including high-precision measurements of nearly 1,7-billion stars, revealing previously unseen details of our Galaxy. The new data includes positions, distance indicators and motions of more than one billion stars, along with high-precision measurements of asteroids within our solar system and stars […]

Downloading, analysing and reporting power quality data

This article describes five steps to simplify and automate the analysis and reporting process. Understanding energy consumption or power quality issues requires data. Measurements are the ideal form of data, but this data must be turned into usable information in a process most commonly referred to as analysis and reporting. The analysis takes the raw […]
