The paper deals with the principles of determining real estate boundary lines in the spatial aspect, and evolution of the concept of real property. The attributes describing real estates are given together with the principles of their measurement and presentation. The principles of attribute description and identification are discussed as dependent upon the group of economic activity connected with real estate resources. Selected public land resources are also characterized in the paper.

The paper presents proposal of classification in the communal real estate in complex formulation. It created classification was based was on two basic criterions of division of municipal real estate, such how: the object of farming – the division on land immobilities and built-up (the buildings , building and premises) as well as the function (the actual way of utilization), what fill or can to fill the recorded in communal real estate. The functions of immobility with municipal supplies were analysed in connection with own tasks of communes. The worked out classification has the character the arranging the economy the communal supplies the immobility and state contribution to rationalization of methods and forms the farming the public property.

The main objectives of the present study were to define the concept of spatial order in rural areas, and to develop a method for its evaluation. Spatial order indices and their measures are proposed in the paper, followed by a description of successive stages of spatial order evaluation, and practical applications of the method proposed. The method for spatial order evaluation in rural areas was tested in a selected investigation area - Lauda District, Lidzbark Warmiński Commune. The results obtained are presented in a tabular and graphical form.

The objective of the present study was to determine three basic zones of the Proszowice town, i.e. central, transition and peripheral, their functions and correlations between them and spatial management including the collective form of a housing estate and particular architectural forms. The paper focuses also on the problem of chaotic management of developed areas and the necessity to make it more efficient and orderly. This should allow to improve the living conditions of residents of these areas, and to restore the spatial and social-economic order indispensable for harmonious urban development.

The objective of the present study was to make a comparative analysis of selected social and economic indicators characterizing the directions of transformation of Polish agriculture in the regional, national and European aspect. This analysis shows that six provinces of northern and western Poland are characterized by similar standards of agricultural development as the other European Union member states. The other Polish provinces, at the present stage of their development, clearly differ in this respect from the above standards.

The valuation of a land expanse configuration was made on the basic of a chosen group of farms whose parameters were similar to those characterizing the whole village. The chosen group includes about 5% of a total number of farms in this village. The researches were done in the Łapsze Wyżne village (as an example) –one of the most disaggregated mountain villages. The area of an average farm in this village is 5 hectares and such a farm consist of 45 plots. The average area of plots designed for grassland is 0.10 hectare. The most favourable feature of a land expanse in the group of plots tested in the study is their length – 92 metres (an average). This length can be considered proper for cultivation with a horse. A too small area and width of plots are the main reasons for high cost of cultivation. In the village almost half of plots with grassland are 5 to 10 metres wide, whereas about 90% cover an area of less than 20 are. There are almost no plots larger than 1 hectare , i.e. appropriate for cultivation with a tractor.

The disappearance of landscape elements not used for agricultural purposes could be observed in recent years on farmlands in many areas of the world. These are usually linear landscape elements that mark the boundaries of crop fields, characteristic of the traditional farmlands in Europe. Patch landscapes elements are woodlots (mid-field clumps and shelterbelts), single trees, gravel pits, bogs and water reservoirs. The work presents quantitative characteristics of landscape elements which are not used for agricultural production in an area of intensive farming of the Wroclaw Plain (SW Poland, Lower Silesia Province). It also determines the relation between linear landscape elements and certain types of habitats not used for agricultural purposes. In the study area the overall number of such landscape elements was 336. Patch biotopes (mid-field clumps, shelterbelts, reed beds, bogs and water reservoirs) (n=186) occupied an area of 109.03 ha. The overall length of linear biotopes (water-edge woodlots and avenues) (n=194) was 53.065 km. Abandoned fields (n=94) occupied an area of 399.84 ha. The presence of linear landscape elements (roads, watercourses and railway lines) had a significant effect on the number of habitats not used for agricultural purposes in the 18 precincts studied. The preservation of landscape diversity is of vital importance in the process of spatial planning in farmlands. This should be effected through the preservation and restoration of habitats not used for agricultural purposes, and development of a network of connections between particular landscape components, enabling the displacement of living organisms.

The paper presents a proposal for the application of decision trees - a popular technique of data exploration - for real estate market analyses. The study area was the Krowodrza district, where the market of residential real property (sale prices and advertisements) had been analyzed. In particular the aim of the research was to show analytical possibilities of decision tree applications for the prediction of the real estate value.

The paper presents the possibilities of the application of decision trees for the elimination of land plot attributes of low-importance, taken into account during mass appraisal. The influence of various real estate features has been discussed and a method for the elimination of attributes of low-importance has been presented.

The local real estate market is moderately homogenous as far as the level and degree of development and market conditions, including supply and demand as well as the level of prices, are concerned. The location of real estates is one of the factors directly affecting their value. The objective of the present study was to assess the influence of the city of Wrocław on the development of a local real estate market in the suburban areas. The research was conducted in the village commune of Długołęka, including 28 places evenly situated in the commune. The comparison of prices and values of real estates and the maps of the area indicates that the commune is not a homogenous market of estates for development of residential areas and service facilities. The estates for residential purposes situated in the nearest vicinity of the administrative borders of the city of Wrocław are of the highest value. As far as the estates for service facilities are concerned, these situated along the national road Wrocław-Warszawa and close to the administrative borders of the city have the highest value.
