ground-truth validation
a re-blog from earth observatory’s siberia field work
“Western Siberia is, in places, remote. However, much of the region can be accessed by a system of roads and rivers. When planning this expedition, the scientists needed to find the location of GLAS footprints – measurements taken by the Geoscience Laser Altimeter System aboard the ICESat Satellite - in the area as well as find routes to enter those footprints. The goal of the expedition is to measure by hand, on location, as many GLAS footprints as possible in the study area. This is called ground-truth validation, and is an essential part of understanding data acquired by remote sensing instruments. “
Need to find out more about this relationship between remote sensing and on the ground measurements.
pollution in sim city
Thinking about how to overlay pollution information into an environment, how to take the abstracted information and actually describe it by group walking with coMob. Then I remembered the maps in Sim City, the overviews, where you can see your city in plan view (rather than the isometric view you usually get). The plans have information about pollution, traffic, power use, water use, fire risk etc.
