Time: 3 hours Max Marks: 80
Answer any FIVE Questions
All Questions carry equal marks
1. Describe the general topological vector data model. How does it differ from the
spaghetti models? How is this difference achived? What are some examples of
topological models? Describe their differences. What advantages or disadvantages
does each have? [16]
2. (a) Explain about spatial, spectral and temporal resolutions.
(b) Write short notes on energy interactions with atmosphere. [7+9]
3. What is hydrological cycle? Illustrate this cycle in detail. [16]
4. (a) Explain buffering techniques:
i. Point Buffering.
ii. Area Buffering.
(b) Describe:
i. Topological Overlay.
ii. Vector Overlay.
iii. Raster Overy. [16]
5. (a) Define remote sensing and enumerate the process of electro magnetic remote
sensing.
(b) Mention any eight application areas of remote sensing. [8+8]
6. Explain floods and droughts. Also explain how remote sensing and GIS is useful
for mitigation of this. [16]
7. (a) Differentiate between oblique photographs and vertical photograph.
(b) The relief displacement for the tower at A is 2.01 mm, and the radial distance
from the center of the photo to the the top of the tower is 56.43 mm. If the
flying height is 1220 m above the base of the tower, find the height of the
tower. [8+8]
8. Write detailed notes on:
(a) Geographical entities
(b) Topology. Also give four examples for each. [16]
