3. 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) 3
4. Brief History (*2) 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) 4
5. Brief History Con’t (*21) 18th Century the Transit was invented 19th Century numerous error calculations in mathematics were discovered (*19) 5
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) 6
7.
8. Evolution of Surveying Technology Con’t (*4) 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 (*22) 8
10. Digital Interface (*10) User friendly operating system (M.S. Windows CE. Net 4.2) High speed processor- Intel PXA 255 400 MHz Full colour touch screen (*12) (*11) 10
11. Imaging , Scanning & Robotics (*11) 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
13. Higher productivity Independent Control allows full control by utilizing wireless systems such as U.H.F (Radio Transmission) WiFi Bluetooth (*23) (*14) 13
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) 14
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) 15
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? 16
