6 NUMBER OF LAND RIGHT DOCUMENT

7 DOL VISION "To be core mechanism in driving land management for the utmost benefit for the people and country development with standard management and service" The registration of rights and juristic acts in each year are in between 6-8 million cases and can collect revenue for the Government at the average of 70,000-90,000 million Bath (2,200-2,800 million USD)

8 DOL CORE FUNCTIONS Protecting right in private land Managing public land Conducting land survey and mapping Issuing land right document Registering of rights and juristic acts on land and immovable property Promoting real estate business Managing land information

9 DOL RECENT HIGHLIGHTS The National Land Information and Mapping Centre Project aims to be the central integrated organization of the utilization of land and mapping information The Improvement of Land Surveying by RTK GNSS Network aim to improve land surveying method from the Second Class Survey (no geographical coordinate) becoming to First Class Survey

22 Cadastral Survey In the Department of Lands two classes of cadastral survey are classified The First Class Survey The Second Class Survey According to the Ministerial regulation No. 6 and No. 49 (B.E. 2554) issued under the Land Code Act (B.E. 2497)

23 Cadastral Survey First Class Survey N1, E1 N2, E2 Area from UTM Coordinates N4, E4 N3, E3 Observation of distances and angles from control points (with geographical coordinate) to boundary marks Mathematical methods are used to calculate boundary marks coordinates and area.

24 First Class Survey Cadastral Survey Survey Instruments Theodolite / Chain Theodolite / EDM Total Station = Theodolite + EDM GPS RTK GPS Total Station + GPS = Smart Station Department of Lands

25 First Class Survey Cadastral Survey Total Station

26 First Class Survey Cadastral Survey RTK GPS

27 Second Class Survey Cadastral Survey The second class survey is done by offsetting method by chains or steel tapes from control points to boundary marks or by using aerial photomap to identify land corners Survey instruments and material used : chain or steel tape; aerial photomap.

37 Solution of RTK GNSS Network

38 Typical RTK GNSS method RTK Base Station at known position Rover Station (user)

39 Q: What is CORS? A: Continuous Operational Reference System Running for 24 hours High precision coordinates Variable service 24h static observation of reference station Centimeter accuracy Accuracy independent from rover-tobase distance

44 Private Surveyor Act 2535 According to the Private Surveyors Act 2535, the Private Surveyor Board was set up with the main activities as follows: - To set the qualifications and background of the person who will be private surveyor. - To Issue a license to a private surveyor and give permit the establishment of private surveyor office. - To set the standard of surveying equipments. - To set up regulations and practices for the private surveyors and private surveyor offices.
