Technologies

For providing land related services ELB uses modern technology. ELB owns a set of high precision GPS instruments (Ashtec, Javad, Topcon and Leica) and analytic (Leica) as well as stereographics soft photogrammetric (Leica) workstations. ELB’s Headquarters and local offices in each county are connected to public sector Wide Area Network (WAN) by using Virtual Private Network (VPN) technology. Main software technologies for cartographic and geoinformatic projects include a database platform from Oracle with Spatial Option and GIS software from Intergraph (GeoMedia, GeoMedia Pro and GeoMedia Web Map Professional) and ESRI (ArcGIS, ArcSDE and PLTS). The central office as well as all local cadastral offices are equipped with A1/A0 inkjet plotters to produce maps on demand from digital spatial data.

A major milestone for ELB in 2001 was the full-scale launch of the Cadastral Information System (CIS) in 2001. CIS now manages in an integrated way both textual and map data. CIS can be divided into two parts, cadastral data registration tool and public services system working over Internet. Since the end of the year 2000, free public access to the textual part of the cadastral database covering the whole country has been provided via ELB’s home pages, unfortunately the interface is only in the Estonian language at the moment). In July 2001, access to the cadastral maps for 9 counties was added to the service and the full coverage (15 counties) was achieved at the end of the same year. This public service is free for everyone and includes also almost all large scale digital spatial data layers available from ELB as backdrop maps (raster and vector maps, orthophotos), so everybody can use these pages also just as an Estonian web atlas. The service experienced an average load of 30 000 hits per day during the first couple of months it was active. During the following years the average load per month has been as follows:
