Digital Terrain Modeling by Using Real Time Kinematic GPS Data

Total tation(TS) survey is one of the most familiar and accurate technique used for high resolution DTM data collection. However ,some factors such as intervisibility ,prism targeting and unfriendly weather condition are frequently slowing down the speed of survey which mostly leads to cost inflation. Real Time Kinematics GPS(RTK GPS) offers an alternative where less surveyor needed for the survey ,no intervisibilty is required,and survey execution is weather independent. The materials presented in this work are based on the experiment to demonstrate the application of RTK GPS compared to TS survey.
