Sound Wave, Reliable Technology for Land Measurement

Sound wave technology provides a new hope for the performance of land measurement in Indonesia. This technology is very useful for the activities because the use of sound wave technology is not depending on the weather, whether it’s cloudy or bright. "With sound wave technology, devices can continue to be utilized regardless the weather. While the technologies that rely on light waves is considered to be out of date hence the land registration and measurement become constrained and behind schedule," said Dr. Ir. Irawan Sumarto, M.Sc., Deputy Head of Indonesian Surveyor Association (ISI) on Tuesday (24/5) at UGM UC when opening the workshop RTK-GNSS CORS for Cadastral Survey.


With the new sound waves technology, land measurements can be conducted at anytime. Measurement of the land’s corner coordinates will be done quickly. "We know that the measurement is no longer conducted by looking for the technical points around the field of land. It turns out that the points are now scattered in the air, so measuring can be done any time of day, week, month and year," he added.


With a tool that is always in stand-by position, the device can certainly be used to measure the corner of the land anytime. Thus, the government's target to register the entire land within the next 15 years is expected to be fulfilled. "With the volume of work around 50 million or about 3.5 million hectares of land that can be completed within one year, or about 17.500 land measurements daily,  the government will be able to fullfill its target," Irawan explained.


Irawan hopes this technology can be utilized throughout Indonesia. Up until now, only about 40 stations of Continuously Operating Reference Station (CORS)/Land Reference Network Satellite (JPRS) in Java and Bali are used as active and real-time reference to support the land-related programs. "With a variety of references, within two years it is expected to have covered all areas of the country. Therefore, for this relatively new technology, modern surveyors need to be prepared in BPN (National Land Affairs Bureau) and should be able to operate CORS/JRSP," Irawan concluded.
