Spatial Analysis
The spatial analysis category looks at data manipulation techniques in GIS.
Landsat 8
One of NASA’s latest missions involves the Landsat 8, an orbiting satellite whose purpose it is to map the earth and track changes as seen from space. The National Aeronautics and Space Administration has been launching Landsat satellites into space since the early 1970s. The first Landsat satellite was launched in 1972. The Landsat archive, [...]
Analyzing Bike Sharing Demand with GIS
The New York City Department of Transportation (DOT) recently released its report on the background work that went into bike-share station siting decisions. The first Citi Bike stations were installed earlier this month in New York City and eventually hundreds of stations will be built around the city. The first phase of the fee-based bike sharing calls [...]
Using Remote Sensing to Measure Land Deformation
The European Space Agency has developed a new land data processor to create maps of land deformation. Called Wide Area Processor (WAP), the processes uses radar data to measure millimeter terrain deformations. Changes in the surface height of a landscape occur over time. Sinking of the earth can happen as a result of mining, earthquakes, or natural gas extraction. [...]
Line of Sight in GIS
Line of sight in GIS is a phrase used to described the unimpeded view or access from one point to another point across a terrain or surface. Visibility analysis is a spatial analysis of the portions of a line that are visible as opposed to not visible from a starting point. Line of sight is [...]
Monitoring Driver Fatigue from Space
The ESA has recently released a small spin-off company that is going to help drivers around the world stay a little bit safer with the help of space age technology. EstrellaSat’s job is to create long-distance monitoring technology specifically designed to help predict the movements of drivers who work carting mine loads to and from [...]
