Answer 1

SOLUTION)

1. Creation of Image-based GIS from mutilgeodatasets is characterized by wich subsystem of GIS

B) Input

Input subsystem collects data from various resources to generate the best of it

2. Line in the polygon method is characteristics of

B) Vector Overlay

A vector overlay includes combinig points, line or polygon geometry and their associated attributes.

3. Which of the following cannot be achieved by remote sensing

C) Prevention of earthquake

As earthquake can not be detected by a far distance away from the earth but canbe detedcted by the study of earth movements

4. Cell like unit are characteristics of

B) Cellular data structure

9. A passive sensor uses which of the following source of energy

A) Sun

Reflected sunlight is the major source of energy for passive sensors
