Document Summary
Unmanned aircraft systems: high altitude, long range, long duration, for military reconnaissance and strike. Small drones for civilian aerial photography: precision farming and mapping, real estate photography, merchandise delivery (amazon, remote control filming. Remote-sensing tools: spatial resolution = size of the smallest area, or pixel, spectral resolution = range of wavelengths captured by the sensors. Important earth observing system (eos ) satellites: landsat, weather satellites for ozone, temperature, clouds, terra. 3gs (functions) geographic locations: geo-visualization (display & mapping, geo-database (capture, store, query, manipulating & render spatial information, geo-processing (data processing and spatial modeling. Scientific method: generate critical inquiry, formalize questions into a testable hypothesis, select methods of analysis, collect data, conduct experiments, comparisons, reject or accept the hypothesis, document results. A worldwide radio-navigation system formed from a constellation of 24 satellites and their ground stations. Provides information about: time, latitude, longitude, elevation (altitude, velocity and distance.
