Rotterdam, The Netherlands: Dr Andre Streilein, Chief Topography division and Member of the Board, Federal office of Topography, Swisstopo, Switzerland informed the audiences at the GWF-2013 pre-conference programme, about the map products provided by Swisstopo. The products include topographic maps from 1:1 million to 1:25,000, landscape models, height models, image data, orthophotos, multimedia products etc.
With a vision to produce high quality spatial reference data and products derived thereof, Swisstopo is producing swissTLM-3D – the most accurate and comprehensive 3D vector dataset of Switzerland. He said there is a greater need to convince governments that geoinformation is a national infrastructure. He also stressed on the need to bring information, at least the viewing service, to the citizens through modern means at no cost.
Earlier, Godfried Barnasconi, Executive Board, Dutch Kadastre and Wadi Joao Scandar Neto, Director of geosciences, IBGE, Brazil made interesting presentations highlighting their activities and collaborative mechanisms they are evolving to stay afloat in the dynamically changing economic scenario.
Presenting the emerging trends in the use of geoinformation in South Korea, AHN Jung-hoon, Director, planning and policy division, National Geographic Information Institute (NGII) described several initiatives undertaken by NGII.
Understanding the importance and significance of geospatial information in inter-industry promotion like land and environmental management, disaster response and providing web/mobile service to the public, the national geographic information institute is enabling an easy access of geoinformation in Korea.
Korea has set up a National Spatial Information Clearinghouse, inter-government system of 76 systems and 23 organisations – for statistical research, urban hazard mapping, city management etc. However, in the rapidly changing circumstances, there is an increasing demand for geospatial data including national base map. Most users require up to date data than biennial data. A small survey showed that 51% of users wanted fresh data that is less than one year. Keeping this in view, NGII has shortened its policy revision cycle from 5 years to 2 years.
According to the need to provide more recent and comprehensive information, NGII has established national base map advancement project. Major objectives include all kinds of public construction works, 55 kinds of buildings and other structures, road, river, railroad, housing site etc. NGII has also started providing online services and national base map is now available in various file formats for easy access – pdf, shp, gml, tif, ngi, dxf etc.
Informing the details about the study conducted by NGII on the impact analysis on geospatial industry in 2011, AHN Jung-hoon said that from 1993 to 2012, NGII spent about $650 million for building and maintaining its national base map. Estimated budget for national map for next 10 years is $513 million. He informed that the public sector in South Korea had annual benefits of $72.1 million and private sector reaped benefits to the tune of $58.34 million in 2011. In conclusion, he said that the economic benefit of Korean national base map is $130 million/annum.
