Question details

GeoTutor: Geospatial Technologies GPS, GIS, and Remote Sensing 2012 Remote sensing acquires visual imagery about Earth using sensors. This imagery is often gathered from satelites or arcrafts and then analyzed within a Gis. Remote sensing is uselul for understanding things ike sea surface temperature, the distribution of land cover types, deforestation patterns, the growth of cities, and other spatial processes on Earths surface. Passive remote sensing involves the sensor recording energy radiated trom Earth. Examples of passive sensors roude Land ata which is shown in Figure B. This satellie was launched in 2013 to help global changes such as wildfires Active remote sensing means the sensor emits energy to Earth and measures how much energy is reflected back to the sensor Examples of active sesors include Seasat which uses radar to measure sea ice extent, and Cloudsat, which uses radar to measure the properties of clouds to help investigate cimate change. · understand how processes like urbanization and delorestation affect landoover. Other passive sensors map large-scale and changes in sea level Landsat and satellites Figure 81 Landsal 8 colecting imaes
Based on this information, which of the following is correct? View Available Hint(s) Remote sensing satelites can compute statistics on changes in land cover Passive remote sensing emits radiation to Earth Geographic data is otten collected using remote sensing, which can then be processed using a GiS Remote sensing i Remote s a way to measure variabies from a sensor that is in contact with Earth (e g. a thermometer in water measuring its termperature) sensing technologies only use aircralt to collect geographic dafa Submit
