Definition
• “the art of measuring distances, angles, and positions on or near the
surface of the earth. It is an art because only a surveyor who
possesses a thorough understanding of surveying techniques can
determine the most efficient methods required to obtain optimal
results over a wide variety of surveying problems …” (Kavanagh,2006)

Brief History
• First known form of surveying can be traced back to 3000 B.C in Egypt
• 14th Century the Compass was created in medieval Europe
• 17th Century the Vernier Scale was invented
(*3)
(*16)
(*2)
5
Brief History Con’t
• 18th Century the Transit was invented
• 19th Century numerous error calculations in mathematics were discovered
(*19)
(*21)
6
Evolution of Surveying Technology
• Levels– Measuring heights from
distances accurate to +/- 5mm at a range of line of site
– Can take measurements within 360˚ of the level
– Takes flat measurements
– Uses a crew of 3-4 persons
(*18)
7
Evolution of Surveying Technology Con’t
•Due to the curvature of the earth, this would be a sample of an arithmetic procedure that one would need to accomplish in the field to create complicated field notes
(*19)
(*19)
8
Evolution of Surveying Technology Con’t
• Theodolite – Works with both the X and Y axis in
order to collect accurate– Used for measuring angles across
land– More accurate in measuring
elevations at far distances– Uses a 2-3 person crew
(*4)

• New features• Greater accuracy • Higher productivity
Robotic
10
• User friendly operating system (M.S. Windows CE. Net 4.2)
• High speed processor- Intel PXA 255 400 MHz
• Full colour touch screen
Digital Interface (*10)
(*12)
(*11)
11
Imaging , Scanning & Robotics• Creates A 360˚ digital field
book within seconds • IntelligentScan®
distinguishes significant points and features in the field
• ImageDrive ® allows the operator to control the I.S. technology from the data collector and switch from image scanning to prism tracking
®
(*11)
12
Accurate to distances up to 2000 M
(*1)
13
Higher productivity
• Independent Control allows full control by utilizing wireless systems such as – U.H.F (Radio Transmission) – WiFi– Bluetooth
(*14)
(*23)
14
Robotic Equipment
• Using infrared sensors, the total station is able to follow the operator while staking out the property
• The RC-3R is the infrared transmitter/ receiver picks up the signals given by the total station
(*8)
(*6)
15
Robotic Equipment Con’t
• The information is transmitted via Bluetooth or U.H.F from the total station to the Data Collector and is stored
• The reasoning behind the robotic system is to eliminate one person from the crew
• This makes a two person crew a one person crew – saving money and raising productivity
(*6)
16
Conclusion
• The surveying industry has historically pushed the advancement of technology
• Advancing technology eliminates human error from the equation – computer does the math
• With all advancements in automation, jobs become obsolete
• Where is the techno going?
