We live in an information society for which the Internet, as a global system of connections between computers and, consequently, databases stored in them, plays a highly important part. Hence, more and more real property data are available. This article is devoted to the analysis of the opportunities to purchase the Register of Real Estate Prices and Values (RREPV) online from county geoportals. RREPV is one of the sources of information used in the process of real estate value estimation. Pursuant to § 74 of the Regulation on the Land and Property Register, the register is kept by the head of the county. There are 380 counties in Poland, including 66 city counties. Such a big number of administrative units in Poland, along with a great variety of different information and communication systems used for keeping RREPV, results in the fact that online access to the register data is not possible everywhere. The aim of the paper is to present the spatial layout of counties which: created the opportunity to access the National Geodetic and Cartographic Resource data via county geoportals, launched special modules for handling real estate appraisers and made it possible to purchase RREPV data online.
