Q.81. Aerial photographs are studied with the help of
(A) Microscope
(B) Stereoscope
(C) Theodolite
(D) Pantograph
Answer: B
Explanation:
A stereoscope is a device for viewing a stereoscopic pair of separate images, depicting left-eye and right-eye views of the same scene, as a single three-dimensional image
Q.82. The scale on the aerial photography is variable on account of which of the following
(A) Shadows of the objects
(B) Texture of the objects
(C) Relief of the ground
(D) Shadow and relief both
Answer: C
Explanation:
Aerial photography
The scale on the aerial photography is variable on account of Relief of the ground.
Aerial photography (or airborne imagery) is the taking of photographs from an aircraft or other flying object. Platforms for aerial photography include fixed-wing aircraft, helicopters, unmanned aerial vehicles, balloons, blimps and dirigibles, rockets, pigeons, kites, parachutes, stand-alone telescoping and vehicle-mounted poles.

Q.89. Among the following water which will have highest spectral reflectance in visible land
(A) Clear Water
(B) Clay Field
(C) Algae Mixed with Water
(D) Silt and Algae Mixed Water
Answer: B
Explanation:
In its liquid state, water has relatively low reflectance, with clear water having the greatest reflectance in the blue portion of the visible part of the spectrum. Water has high absorption and virtually no reflectance in near infrared wavelengths range and beyond. Turbid water has a higher reflectance in the visible region than clear water. This is also true for waters containing high chlorophyll concentrations.

Answer: D
Explanation:
IKONOS : Resolution: Panchromatic: 0.82–1 m
Landsat TM: Resolution: Panchromatic: 15 m
SPOT 5 : Resolution: Panchromatic: 5 m
IKONOS : Resolution: 2.75-km

Q.93. Which of the following is a GIS operation
(A) Image displaying
(B) Contract Stretching
(C) Map over Laying
(D) Image Enhancement
Answer: C
Explanation:
Overlay is a GIS operation that superimposes multiple data sets (representing different themes) together for the purpose of identifying relationships between them. An overlay creates a composite map by combining the geometry and attributes of the input data sets. Tools are available in most GIS software for overlaying both Vector or raster data.
