Expert-based science is widely on the decline when it comes to computing- and data-based inference worldwide for land- and seascapes as well as the atmosphere. The status of associated biodiversity and its conservation is equally in a crisis-state. In this presentation I will show how open access to data -including citizen science - has provided…

The usual views of air traffic — a single plane in the sky, several planes on approach, even the route map in the back of the in-flight magazine — are deceptive. The truth is that air traffic (and its counterpart, maritime traffic) is a big, messy, complex, ever-evolving morass where this morning’s anomaly is this…

As the planet continues to warm, many decision makers are grappling with how best to adapt to our changing climate. But for these decision makers, the most advanced global climate models are also perceived as being too ‘wrong’ to be useful for planning and adaptation. In response, an explosion of higher resolution ‘downscaled’ climate models have emerged…

Synthetic populations are geospatially explicit representations of households and persons. RTI’s nationwide synthetic populations are derived from American Community Survey (ACS) demographic estimates and ACS Public Use Microdata Samples (PUMS). These synthetic populations match household spatial distributions at 100M grid cell resolution and household demographic distributions at the census block group resolution. Synthetic populations are…

Combining GPS units with accelerometers is becoming a common method of objectively assessing adult physical activity locations. However, few best practices have been proposed for designing these studies. Using accelerometer and GPS data collected from over 200 adults in five cities, 10+ minute bouts of physical activity were given location codes with a Google Maps-based…
