Application of difference analysis perception in comparison of calculation of the effects of floods
(2011) Dąbrowski, Janusz
The article presents the application of difference analysis perception in comparison of calculation of the effects of floods. The year 2010 was for Poland particularly acute in terms of flooding, which resulted in damage to the infrastructure of many communities. In the case of damage to the state property, a local government authority may apply for grants to remove these effects. The data contained in the work makes up a collection of 142 pairs of independent calculations of the effects of flooding on the Podkarpackie province. The first calculation was made by specialists in a municipality, and the second verification by the committee representing the interests of the State in the person of the Governor. The basis of calculations was the data from the Secocenbud. The difference analysis is usually applied while comparing two independent perceptions describing the same value. Surveyors often use the difference analysis perception in measurement of angles, length and height differences. While property estimating, the difference analysis perception is hardly used due to lack of relevant data. The data compiled and presented by the author concerns calculations made in late May and June 2010, with dozens of municipalities of the Podkarpackie province. With so little time-interval we have completely ignored in the analysis the impact of the economic and environmental impact on the value of real estate valuation. An additional advantage of the analysis is the fact that all the valuation estimates mainly the effects of flooding in relation to road infrastructure. With such a selection of data it was possible to carry out a thorough analysis of differences in perceptions. The article shows a certain regularity associated with the valuation of the effects of floods being so far in the field of speculations and assumptions due to lack of data. Based on the data and its interpretation, the article contains practical proposals for local and state government.
