Abstract
This paper is of a research – cognitive feature. It presents a methodology for the identifi cation of point objects (trees) in a wooded area, having an average degree of terrain details condensation and small denivelation of the terrain. The applied methodology was based on the use of hand-held GPS receivers with navigation applications and functions. The advantage of the presented method is the speed and relatively low cost of development. In the economic and technical aspect the presented method for identifying trees may be applied in practice, eg. by the forest service. (Of course, using one of three types of receivers, and not all at the same time – as has been the case for the research). It can be used not only for labeling or identifi cation of individual species of trees, but for example feeding grounds, waterholes and any peculiarities occurring in the area. In addition, positioned and placed on the local thematic maps (eg. travel maps) places particularly worth a look or even those that should be avoided due to the risk of, which may occur in them, may aff ect the improvement of the quality of tourist information. They can also serve the purpose of the promotion of the region. Navigation devices used in the fi eld and described in this publication provide the accuracy of coordinates determination (positioning) even of 2–3 meters [4] for some point objects and can be used for updating the maps and thematic databases of topographic objects.
Highlights
This paper is of a research – cognitive feature
Measurements were carried out with the two navigation type, handheld receivers GPSmap 76, Garmin GPSmap 62st, completing and verifying them with the receiver of a wider range of applications – Nautiz X7, in which the map was recorded as an orthophotomap
The aim of the study was to determine the differences in the obtained coordinates using different types of GPS receivers
