aim to develop different types of skills so that students are able to acquire following
competency:
Prepare survey maps/drawing after carrying out different kinds of field surveys
using advance surveying equipments.
Find out various physical quantities like length, area, volume, elevations, angles,
latitude, departure, etc by interpreting survey drawings.
3. COURSE OUTCOMES
The theory should be taught and practical should be carried out in such a manner that
students are able to acquire different learning out comes in cognitive, psychomotor
and affective domain to demonstrate following course outcomes.
Use Theodolite for the measurement of horizontal and vertical angle

7. SUGGESTED LIST OF EXERCISES/PRACTICAL
The practical/exercises should be properly designed and implemented with an attempt to
develop different types of skills (outcomes in psychomotor and affective domain) so that
students are able to acquire the competencies/programme outcomes. Following is the list of
practical exercises for guidance.
Note: Here only outcomes in psychomotor domain are listed as practical/exercises. However,
if these practical/exercises are completed appropriately, they would also lead to development
of certain outcomes in affective domain which would in turn lead to development of Course
Outcomes related to affective domain. Thus over all development of Programme Outcomes
(as given in a common list at the beginning of curriculum document for this programme)
would be assured.
Faculty should refer to that common list and should ensure that students also acquire
outcomes in affective domain which are required for overall achievement of Programme
Outcomes/Course Outcomes.
