13). which of the following is the correct term for an aerial photograph that has been mathematically corrected for camera tilt and topography and contains a uniform scale? a. false-color photo b. topophoto c. satellite image d. orthophoto e. multispectral photo 14). measurement of an object's characteristics from a distance using reflected or emitted electromagnetic energy (electromagnetic radiation or emr) is the definition of what? a. map algebra b. reclassification c. remote sensing d. resampling e. raster analysis 15). these are a type of sensor that respond to external stimuli. they record radiation, originally from the sun, that is reflected from the earth's surface and from objects. because of this, they can only be used to collect data during daylight hours. examples include multispectral sensors such as landsat. a. passive b. vector c. floating d. active e. spline 10). which of the following is a remote-sensing technology that transmits radio waves to objects and measures the reflected energy? it can be used day or night and can penetrate clouds and vegetation. a. radar sensors b. landsat sensors c. photo sensors d. lidar sensors e. multispectral sensors 11). these are a type of sensors that transmit stimuli and then measure the amount of the stimuli reflected back to them. examples include lidar and radar. a. passive b. vector c. floating d. active e. spline 12). this is a remote-sensing technology that uses an airbome laser to transmit light out to an object. some of the light is reflected back to the sensor, where it is analyzed to yield information about the target. a. radar sensors b. landsat sensors c. photo sensors d. lidar sensors e. multispectral
