Concept of rural space control system applying photogrammetric methods
The paper is of methodicalic nature. Its purpose is to investigate the possibilities of using modern photogrammetric methods for the establishment of databases of the agricultural space control system in Poland. Following the guidelines specified by the Agriculture Committtee of the European Union, the farm register shall be the basis of the farmland control system in Poland.
The research was conducted in order to analyse and choose an optimum option for the organizational structure of the farmland control system in Poland - the one within the framework of which it would be possible to have an effective record of outlays and effects related to the restructuring of Polish agriculture, based on objective photogrammetric methods of measurement and interpretation of aerial photographs. This refers to both the initial stage of the inventory control, as well as to the subsequent control stages, performed at any given time, testifying the intended effects of the structural changes of farms.
The aim of the research performed and described in this paper was to prove the legitimacy of choosing photogrammetric methods for the registration of the current state of farms, before their restructuring, as well as for the registration and evaluation of structural changes of the farms which will use subsidies provided by the European Union.
Another purpose of the research discussed in the paper was to search for optimum methodical solutions which could meet the expectations formulated by the European Union with reference to the farmland control system perceived as an efficiently operating mechanism of control over a reliable expenditure of non-returnable funds offered by the European Union for the restructuring of agriculture in Poland. The restructuring is aimed at improving the quantitative and qualitative standards of agricultural production in our country.
The research included photogrammetric methods and techniques as well as methods used for the transformation of the existing analogue cadastral maps into a form which can be used to create databases of the farm register, which constitutes the basis for the farmland control system in Poland.
In the research account was taken of the suggestion made by the European Union according to which its member-countries as well as those aspiring to the European Union can create decentralised databases of the farm register within the control system on condition that the same administration procedures will be employed in all these databases as regards the registration and input of data. It is essential that we follow the principle that these procedures, serving as standards, should be binding in all the member-countries and that the database sets should be compatible.
The research on the methods of establishing numerical sets to supply the databases of the farm register focused mainly on the analysis and examination of methods that enable us to:
- transform the analogue sets of cadastral maps, in the scale of 1:5000, to a digital from; and
- transform highly accurate and up-to-date aerial photographs taken in the scale of
- 1:26 000 and 1:5 000 to their orthogonal form.
Results of the research on these methods as well as the obtained practical results have been discussed in respective chapters of this paper.
The conclusions from the performed analyses and research clearly indicate that photogrammetric methods are the optimum ones as regards the creation of the initial and control contents of the databases of the farm regsiter, which constitutes the basis for the farmland control system.
