Abstract
Land and mortgage registers, the cadastre of real estate, the records of the utility networks and spatial development plans are basic information sources used for valuation of real estates. It is useful to collect them in the form of a suitable database. Such database should contain information describing each real estate. However, the construction of an independent database supporting the process of real estate valuation is long-lasting and expensive. GIS technology can help to solve this problem. One can suppose that data from GIS databases would be able, at least partially, to fill databases supporting valuation. In this paper the results of an analysis of the necessary content of such databases are presented. The problems with databases being able to constitute the potential source of such data were also noticed. They are distracted, they are managed by many different institutions and the access to them can be troublesome. This is why the review of existing and planned GIS databases was also performed. The analysis of their availability and the detailed subject range was conducted. It proved that they do not contain the complete set of the required information to make the valuation. Particularly the spatial attributes of real estate and relationships with other objects in the direct and further neighbourhood (utility networks, major roads, industrial plants) are essential. Most often such data are not recorded directly in the database. One of the classical applications of GIS are spatial analyses allowing the determination of spatial attributes of objects and relationships between them. Data processing tools (analytic functions) can be used to calculate some real estate attributes, required in the process of the valuation. The comparison of required and available data and the knowledge of the GIS software functionality allowed to present the proposal of the data range, which may be transferred directly or generated by analytical tools of the GIS software. The results of earlier research, which showed many possibilities of "non-standard uses of analytic functions of the GIS software, partially confirm such statement. In particular, the buffering function, belonging to the canon of spatial analyses, which can determine the real estate distance to other objects, and functions from the domain of geographical networks analyses, making possible calculation of shortest paths, deserve the attention.
