Nigeria - Opis:
- The aim of the presentation is an attempt of a new approach to the matters of regionalization of geographical space and valorization of scenic units made from the outside reference point (in the orthogonal grid). Such an opportunity to take a look from another perspective is given by analysis of aerial and satellite photos, and DTM. Regardless of the adopted way of perceiving the landscape: either as a peculiar spatial structural-material unit (an approach typical of natural sciences), or a physiognomic approach (typical of humanist and technical sciences), the landscape requires appropriate categorization and evaluation. The presentation shows methods which allow for multi-criterion evaluation of spatial units, and then basing on this, suggest possibilities of new spatial divisions. From the point of view of analysis of Sat images and DTM, the most important methods include: Cartographic methods, like: bonitation method, matrix method of determining landscape value, landscape model as surface features, method of determining boundaries and ranges of scenic units, their features, intensity, needs, significance, relations, etc., method of cartometric determination of outlines of objects (scenic units) as basic fields of evaluation – determination of shape and size; Terrain methods used mainly in landscape architecture, like: method of scenic interiors and units, method of impression curve by Wejchert, method of rural landscape classification by Sóhngen, “photographic” method by Cymerman and Hopper, Methods of landscape evaluation based on the infrastructure value (landscape as an element of the cultural-architectonical value) e.g. evaluation and valorization of landscape by means of assessing the value of object included in it, e.g. property, building structures, monuments; Methods of functional evaluation e.g. agricultural, forest, urban, etc.; Methods of evaluation of the photo-tonal value (colour range); Methods of landscape evaluation by means of selected statistical parameters (e.g.) basing on provisions of the fuzzy set theory for the value of space represented by the open space index, characterized by parameters of descriptive statistics. These methods will be presented using several examples of open space value estimation procedures in LandSat photos and DEM models from the region of Nigeria. The presentation will continue with selected methods being used for identifycation and determination of the range of uniform scenic value zones and transitional zones. Cartometric extractions of outlines of scenic units as basic fields of evaluation will be shown, types of landscape discussed and basic statistics describing its structure presented. The authors will also refer to the issues of limits of landscape use and their practical meaning, e.g. in tourist terms. At attempt of classification and valorization of separated fields has been presented, along with estimation of the level of their uniformity, rank and usability.
