DIGITAL TERRAIN MODELING (DTM) WITH RTK GPS FOR CERTAIN ENGINEERING USES

Digital terrain modeling is a process to obtain desirable models of tbe land surface. The
objectives of this project are to produce a DTM witb RTK GPS as well as getting familiar with
RTK GPS usage. This project covers tbe understanding on dealing with RTK GPS equipment as
method for data collection to create DTM. The methodology involved preparing tbe RTK GPS,
preparing tbe case study area, starting collecting data, processing tbe collected data, creating tbe
terrain modeling and modeling analyzing. The DTM can be further analyzed to estimate tbe
volume for cut and fill of tbe area at certain height. RTK GPS method is recommended for
survey metbod straightness, consume less time for collecting data in generating DTM and
suitable for all types of surveys.
