Forum highlights evolving usage of g-tech

Jakarta, Indonesia: Asia Geospatial Forum concluded here on a high note. In his valedictory address, Ir. Budhy Andono Soenhadi, Prime Secretary, BAKOSURTANAL, Indonesia, hailed the conference as a success and observed how use of geospatial technology is evolving to the next level across various sectors in Indonesia. Earlier, the day witnessed deliberations on various technologies and applications through a number of seminars and sessions. Asia Geospatial Forum is organised by Geospatial Media & Communications.

Various aspects related to spatial information in mining and oil exploration processes were discussed in the seminar on mining and exploration. Ir. Prima Muharam Hilman, Head of Information Division, Center for Geological Resources, Geologic al Agency, Indonesia, discussed the use of GIS in mineral prospectivity analysis to support the preparation of new mining permit areas in Indonesia and concluded that Regional probabilistic models of frequency ratio and weight of evidence are a useful technique to evaluate the mineral potential. Sr. Razali Ahmad, Senior Manager – Geomatics Department, Technical Services Division, Petronas Carigali, Malaysia, while highlighting the spatial nature of oil exploration activities, stressed on the importance of integrity of spatial data and illustrated the losses that can incur in the case of inaccuracy of this data. Pugoh Sarwanto, Head of Topography Services, Total E&P Indonesie, described the features of the Enterprise GIS incorporated by the organisation and how the organisation is benefitting from the same.   

Another session brought to the fore the use of geospatial technology in addressing various issues related to urban development and governance. Oliver T. Macapinlac, Assistant Professor, University of the Philippines, discussed the growing phenomenon of urban heat islands with increasing urban population and presented a case study creating a simulation of different urban processes such as land cover change model and Urban Heat Island (UHI) model and outline the role of RS, GIS, and agent-based or micro-dynamic models in the creation of an integrated spatial data and process model. Highlighting the effect of spatial mismatch between city planning area and actual urban area on environmental loads in local cities in Japan, Tanaka Koichi, Associate Professor, University of Tokushima, Japan, stressed on the necessity of appropriate combination of both public transport and land-use regulation in city planning as a way of reducing environmental loads. He then highlighted a study undertaken in this direction. Kailash Agarwal, Regional Head – GIS Business, Asia Pacific, NIIT Technologies, Singapore, presented instances of GIS-enabled governance from various parts of Asia and suggested leveraging infrastructure and data to build geo mash up applications.

Land management is one of the key consumers of geospatial technology in the Asia Pacific region, and the session on Land Administration brought forth some initiatives in this segment. The Land and Surveys Department, Sabah, Malaysia, has established SALIS – Sabah Land Information System, with an objective of accessibility to information for better decision making and fast response and quality services. HJ Safar Untong, Deputy Director of the Department described various features of the system and asserted that SALIS supports the vision of “spatially enabled government.” Dr. Irawan Sumarto, Director – Base Mapping, National Land Agency, Indonesia, took the audience through BPN’s objectives for 2014 and the organisation’s strategy for land data management. Do Duc Doi, Director of Center for Land Information and Archive, General Department of Land Administration, Vietnam, described the development of Multi-Purpose Digital Cadastre Database (MPDCDB) in the country. He informed the audience about the investments made by Vietnamese government, including USD 200 million for Vietnam Land Administration Project and USD 500 million for MPDCDB. Budi Harjanto, Head of Sub-Directorate of Valuation II, Directorate General of Taxes, Indonesia, described the role of spatial data in land and building taxation management in the country. Tran Trong Duc, Deputy Head, Department of Geomatics Engineering, Hochiminh City University of Technology, Vietnam, observed that land price forms the basis for calculation of financial charges, fees and any other financial obligations concerning uses of land and described a model using GIS to calculate the positioning level and price of a land parcel.
