2 CORS Technology 22/12/2009Footer2 Studying movement of the earths crust Reference datum research and precise orbit determinations, Augmentation services of GNSS for navigation, surveying and mapping (Source : Leica)

3 Technology Management Technology Impact Assessment a systematic attempt to foresee the consequences of introducing CORS technology in all spheres it is likely to interact with Strategic Environments – Opportunities – Challenges – Threats 22/12/2009Footer3 Surveyors are user Equipment costs are decreasing Other services of survey business Education. New jargon, new concepts. Requires effort to keep up- to-date with changes Danger that GNSS will become too easy. What else can the modern surveyor offer clients to maintain an advantage over competing professions?

4 Assessment Activities Collect and analyze existing documents/literatures – CORS systems and equipments – BPN RIs internal documentations BPN RI Cadastral Measurement Technical Standardization BPN RI Surveying Technical Manual and Instruction Guide Institutional Strategic Plan and Website of BPN-RI Survey and Interview – Local Land Title Offices (Kantah) Kabupaten Tangerang, Kota Bogor and Kota Bekasi – Data Center and Central Office of Survey, Survey and mapping of BPN RI 22/12/2009Footer4

5 STIP Methodology Scope Topic, Scope, Time Horizon Technology – Performances ; methods/algorithms (standardized or non standardized), accuracies, minimize distance dependent error, maximize use of satellite data, server or rover controlled network solution, traceability and repeatability, consistencies, cost of its development strategy (station distribution, scalability and hardware material component flexibility) and also business model between provider who supply the data and information and the user. – Information and telecommunication technology which feasible and performed practical, efective and reliable. – Alternative technology assessment could also be done to prevent technology failure so that we still have subsitute technologies. 22/12/2009Footer5

6 STIP Methodology Impact – what benefits are to be expected from CORS/JRSP technology economic and commercial, or environmental improvement, health benefits, or improvements in the social or political fabric of society – what needs does it satisfy, and – why is it superior to present, or rival technologies? Policy measures such as how much money invested, how much grant and subsidies given by the government during the development stage. Tax holiday offered in the services of the land titling. Training and program socialization, regulations and supporting facilities, even direct administrative support such as Program Larasita from BPN-RI. 22/12/2009Footer6

Tangerang experiencing an average of survey speed 100 land parcels and 30 control point per day using CORS technology Networked Transport of RTCM via Internet Protocol (NTRIP). Pilot Project

9 Existing & Expected Architecture 22/12/2009Footer9 Existing bandwidth allocated for each Local LTO 128 kbps, and bandwidth allocated for Deputi 1 BPN-RI (including master controller) 512 kbps. Around 400 of 500 Local LTO all over Indonesia have established data communications. Data communication provider depend on available local provider and their geographical location

16 Summaries 22/12/2009Footer16 CORS/JRSP technology could potentially support BPN-RIs cadastral tasks and functions efficiently and effectively to survey and mapping land parcels challenges such as : 1.provide national cadastral reference point network, 2.accelerate land parcels survey and mapping problem solving 3.unifying coordinate reference system of land titling which is in turn to give certificate on a land parcel There are many remaining infrastructure problems and constrains in applying CORS technology, such as Information and Data Communication infrastructure, which will be facing a high risk of failure especially in giving real time services. Therefore, in the near future it should need improvements and comprehensive actions to overcome those infrastructure problems before this technology is widely applied by BPN-RI

17 Recommendations 22/12/2009Footer17 Need to have strategic plan, including scheduling and budgeting to implement CORS system all over Indonesia. The strategic plan should consider aspect such as: 1.Improvements and up-gradable of hardware and software of the system 2.Futuristic data security improvement Improvement on data management, human resources development, defining business process and CORS system maintenance.
