It will take 264 years to finish surveying all the second order control points in Indonesia, unless something changes.
The second order control points, of which there are several thousand, are derived from zero and first order points. As the order rises, the accuracy of the point may be expected to fall. Nevertheless, second order points are essential for practical surveyors who wish to fix the position of some object on the Earth.
Speaking at the South East Asian Survey Congress (SEASC 2009, 4-7 August) in Bali, F.H. Adiyanto from the Badan Pertanahan Nasional - the national land agency - said the current program to update the accuracy of the control points is serious under-resourced.
The plan to fix the problem is to establish a nationwide Continuously Operating Reference Station (CORS) network. This has the potential to improve the productivity of surveyors, but only after a program of legal reform that makes it possible to use positions derive from GNSS receivers to mark cadastral and other points.
Although government regulation 24/97 gave legal recognition to the WGS 84 datum used by the GPS, this did not confer the ability to use the CORS network.
