Guru Gobind Singh Indraprastha Vishwavidyalaya 2007 B.C.A Computer Application Geographical Information System - Question Paper

Q1 (a) elaborate the basic analytical capabilities that 1 would normally
obtain in a modern GIS? (8)
(b) discuss how remotely sensed data can be used as input to GIS (7)
Q2. (a) define the vector data structure. How does it differ from raster in
In its ability to locate objects in space? (7)
(b) elaborate possible advantages and disadvantages of using a raster
GIS as opposed to vector? (8)
Q3 (a) Convertin ranging from raster and vector data structures can produce
outcomes that degrade the quality of the initial imput. What primary
issue might occur during conversion from vector to raster?
(b) elaborate dagling nodes? Overshoots? Undershoots? How are these
caused? What can you do to avoid them?
Q4 (a) What is edge matching? Why is it needed?
(b) Why is a missing polygon tag point a problem? Why do we
Sometimes end up with missing or multiple tag points? How can
this outcome be avoided?
Q5 (a) elaborate map projections? What is their purpose? elaborate the
Three basic families of map projections?
(b) elaborate networks? How do they differ from simple lines? What needs to
simple line, in a GIS?
Q6 (a) define the TIN model. How does it differ from raster models? Why is
It necessary to develop such a model for vector GIS?
(b) elaborate a few obvious limitations of the manul overlay process?
What advantages have been offered through GIS?
Q7 (a) What is a relational database management system? How does it work?
What advantages and disadvantages might it have over database
management systems of other types?
(b) What is the major difference ranging from hybrid and integrated GIS
system? provide a neat schematic sketch of data storage and access in every
system.
Q8 Write shorts notes on the following:-
(a) GIS and Emergency Response Planning
(b) Role of GIS in environmental management
