Graceful Drawing & Engineering Surveying - By: Dr. D.S. Merchant

Engineering surveys are particularly useful to gain the actual values of variables under study, and the relationship bonding among them. Surveys are suitable as a balance to other observations. This adds knowledge through "triangulation" as one of several methods.

Survey approach has the following strengths and weaknesses:

Strengths:
Surveys are easy to administer.
Surveys are simple to score and code.
Surveys determine the values and relations of variables and constructs.
Surveys can be reused easily, and provide an objective way of comparing responses over different groups, times, and places.

Weaknesses:
Surveys are just a snapshot of behavior at one place and time.
They do not provide as rich or "thick" description of a situation as a case study. They do not provide as strong evidence for causality between surveyed constructs as a well designed experiment.

The survey activities can be considered with the need of a detailed check list to be followed in the development and use of necessary survey instruments.
Among these significant steps are:
• Determination of the unit of analysis (e.g., the individual, group, or organization)
• Pre-testing and use of pilot data
• Assessment of reliability
• Random sampling from a defined sample frame.
• Determination of statistical power of the final analysis.

Instruments used in Surveys:
• Aluminum Sextant
• Anchor Clock
• Antique Compass
• Antique Magnifier
• Antique Survey Instrument
• Ball Watch
• Binoculars
• Brass Diver’s Helmet
• Brass Nautical Lamp
• Brass Sand Timer
• Hand Kaleidoscope
• Magnifying Glass
• Marine Binocular
• Marine Clock
• Navigation Telescopes And Binocular
• Nautical Lantern
• Nautical Microscope
• Nautical Mirror
• Theodolites
• Wooden Binocular
