Transparency with the online-real-estate-price-calculator in Lower Saxony
Kertscher, Dieter
The committees of experts on real estate value in whole Germany and especially in North- Rhine-Westfalia provide standard ground values and general pricing information for developed real estate throughout the country, which is freely accessible via the Internet portal BORISplus.NRW. The information is derived from purchase contracts, which are registered and evaluated by the committees. The Internet portal www.borisplus.nrw.dee is based on the German spatial data infrastructure and uses international OGC standards such as WMS and WFS, which means the standard ground values can also be used for the geoportals of private operators. The initial version, BORIS.NRW, was launched in 2003 and replaced in October 2008 by the redesigned version BORISplus.NRW. 17000 registered users and more than one million hits per month are a sign of high acceptance, not least thanks to a service that is mostly free of charge. On the way to an other online-Service for valuation, Lower - Saxony created the Immobilien-Price-Calculator IPCC for standard-typs of single family-houses, row-houses, semi-detached-houses and condominiums. The address: www.gag.niedersachsen.de, the rate 19,90 per informance of the rough estimate value.
