Joint use of geographic information : cadastral data, general and topographic map data
Tarvainen, Teija and Tarja Myllymaki
This paper presents software interfaces offered by the National Land Survey of Finland (NLS). Based on international standards, these services make data for customerss applications accessible online. All general and topographic raster maps produced by the NLS at scales between 1:8,000,000 and 1:20,000 are available through the software interface used for delivering raster map data. Cadastral data from the Land Information System (LIS), which provides national coverage, is delivered through the cadastral software interface. These software interface services for customers were launched in 2005 and 2006. Use of the services requires a licence, and a charge is made for supplying the data. The software interfaces makes it possible for customers to design applications which use data from multiple resources. The number of applications of this type, however, is still quite small.
