Implication of GDM2000
Implication on Practice i) GPS Positioning and Surveying The widespread use of GPS has further highlighted the need to adopt geocentric datum in this country. Position determination using various GPS techniques have been increasingly being practiced for various survey related applications. The existing GPS networks in Peninsular and East Malaysia which have been strengthened and referenced to the GDM2000 will certainly provide better control for GPS positioning activities carried out by various mapping related agencies. The new GDM2000 will provide better platform for most GPS positioning applications li ti in i future f t for f the th country. t This will encourage the use of GPS as an effective positioning tool without going through the lengthy process of conversion to the old local datums of MRT48 and BT68 The GDM2000 also support the function of Real Time Kinematic (RTK) GPS Network in the country –MyRTKnet.

Implication on Practice ii) Cadastral Survey Cassini projection system for the Peninsular is based on several local datums and realized by their published equations and coordinate of their respective State origin origin. The existing Cassini projection for cadastral mapping was based on the MRT system referenced to the Modified Everest ellipsoid. The existing procedure of converting WGS84 coordinates to their corresponding values in local Cassini system involves several transformation steps such as the following: 9
WGS84 → MRT → RSO → Cassini
The geodetic coordinates of a point determined in GDM2000 (on the GRS80 ellipsoid) using GPS can now be projected directly to their related geocentric Cassini plane coordinate values ( as shown in the next slide) 9

Implication on Practice iii) Topographical Mapping The existing map projection used for topographical mapping in Malaysia is the RSO based on the MRT48 and BT68 systems . The procedure of converting WGS84 coordinates to their corresponding values in local RSO system involves several transformation steps such as the following: 9
WGS84 → MRT/BT68→ RSO
The introduction of GDM2000 will have a significant effect on the topographical mapping products : the coordinates (shift) of points by up to approximately 200 meters in northeasterly and northwesterly directions for Peninsular and East Malaysia, Malaysia respectively. respectively 9 φ,λ GDM2000 (E,N) PMRSO/SSRSO GDM2000 Change in coordinates of map features • 1: 50,000 --- 4 mm on the map • 1:10,000 --- 20 mm on the map

Implication on Practice iv) GIS Users The GDM2000 provides coordinates that are appropriate for applications at all levels and allows the easy integration with other information technologies such as GIS. GIS The future development of National Spatial Data Infrastructure (NSDI) is being planned to provide consistent national datasets to users on the same coordinate system, that is GDM2000. The NSDI will be based on the GDM2000 and all datasets will be supplied to users in GDM2000 coordinates. Integration of NSDI with other ICT such as GIS and GPS can be done. The use of GDM2000 will minimise confusion for all users and provide maximum accuracy where precise spatial information is required.

Implication of GDM2000
Socio Economic Implications The user segment of GDM2000 will be: 9
Government Department Agencies - JUPEM, Land Departments, Planning Department, Local Governments and Municipalities.
9
Non-Government Organization- private surveyors
9
Public.
Government agencies and the private surveyors will be most affected since they directly involve in cadastral survey practice and the main user of the topographical and cadastral mapping products . Private and public organizations will need to assess both the impact and benefits of adopting p g GDM2000 in terms of their current and future operational requirements, financial, administrative and managerial issues. The adoption of GDM2000 will accommodate the integration of spatial datasets and consequently will provide better data sharing, handling and management of the related datasets. The new datum will also encourage consistent or uniform spatial data standard across the country.

PENGGAMBARAN UDARA
Penentuan Titik Dedahan Kamera
Menggunakan interpolasi. Masa dedahan ditentukan dengan menghantar denyutan genap dari kamera ke penerima GPS GPS, yang mana merekodkan dengan tepat masa dedahan kamera. Koordinat titik dedahan kamera diinterpolasi di antara epok sebelum dan selepas masa di atas.
GPS menyokong penyegitigaan udara Kelebihan utama: meminimakan keperluan bilangan TKB Memadai dengan 4 TKB di setiap penjuru blok untuk pelarasan blok. Biasanya JUPEM guna lebih dari 4 sebagai kawalan kejituan.
