Vertical aerial photo Orthophoto Mosaicked photo Satellite photo Aerial photographs, especially vertical aerial photographs, look very similar with maps. Select ALL the correct statements from the following choices: Aerial photo has non-uniform scales throughout the coverage, while maps have a uniform scale throughout the coverage. Both map and aerial photo are orthogonal representations of the earth's surface. Aerial photos contain certain degree of geometric distortion, while maps are geometrically accurate. Measurements made on a photograph are as accurate as on that on maps A satellite with a four-day temporal resolution passes over your house on January 2. The next day the satellite passes over your house will be January 6.
True False Infrared light is invisible to human eyes. True False Which of the following is NOT true of satellites? They are constantly orbiting the Earth They can image much larger areas than single aerial photos can They are restricted to geographic boundaries, much the same way that aircraft are They are, in general, superior to aircraft in terms of their ability to capture images on Earth Landsat 8's multispectral imagery has a spatial resolution of ______. 1 m 10 m 30 m 100 m In a standard false color composite image (near-infrared light in red gun, red light in green gun, green light in blue gun), healthy grass is displayed as ___________ while water is displayed as _________. a) green; blue b) red; black c) red; white d) blue; red High spectral resolution can be combined with high spatial resolution and high temporal resolution. True False
True or False: A remote sensing image with a lower spatial resolution allows the eye to see more detail. a) True b) False Suppose you are asked to differentiate forested and deforested areas in a Landsat8 image with information from only a single band. Which band will you most probably use? Band 5: near infrared Band 4: red Band 2: blue In active remote sensing, a) an operator on the ground needs to activate controls for tasking a satellite to obtain a specific image. b) only the infrared bands in the electromagnetic spectrum are sensed. c) the remote sensing device measures all possible bands in the electromagnetic spectrum. d) the remote sensing device generates its own source of energy and measures the reflection or return of that The Aqua satellite's main goal is to study a) land forms. b) volcanoes. c) weather patterns. d) water cycles. Which of the following satellites would be used to take images of individual single-family homes? a) GeoEye-1 b) Suomi-NPP
c) Landsat d) AVHRR Which of the following is a satellite of NASA’s Earth Observation System? a) Aqua b) Sentinel-2A c) GOES d) MODIS Healthy vegetation will have a weak reflection of near-infrared energy and a strong absorption of green energy True False Which color gun/channel is NOT used to create a color composite on computer monitors? a) red gun
b) green gun c) yellow gun d) blue gun QUIZ 3: In the raster data model, ___________________.
