Cadastre surveys with real time kinematic GPS (RTK) as a basis for future survey regulations
Jarrousg, Jad, Ron Adler and Marwan Zeibak
During the last decade, many countries all over the world have adopted the FIG vision "Digital Cadastre 2014" project. Countries are preparing to transition from the analogical cadastre to the future Legal Digital Cadastre system. This transition will include upgrading the surveyor's regulations, which were based on conventional survey measurement instruments on the traditional cadastral system. In order to build a high accuracy digital cadastre database, it is obvious that the national control network will be based on the permanent GPS station control network of the country. Additionally, achieving homogeneity in all the cadastral projects, every cadastral project must be based on GPS measurements. Hence, GPS instruments would be the main instruments for surveying. Since the RTK GPS instrument is considered a relatively new instrument, which began serving surveyors since the middle of the last decade, several cadastral regulations have not included a procedure for RTK GPS measurement. This paper proposes a development of an accepted procedure for reliable cadastral Surveys with Real Time GPS towards the future Survey Regulations. Such a procedure was based on experiment results of measuring 35 control points, which were measured by means of static GPS high accuracy measurements and lead to accuracy level of: 4 to 6 mm in position as well as 7 to 14 mm in Orthometric heights. The experiment area extends on about 52,000 metric dunam.
