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

®

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?
