Abstract

The applicability of thermal photography in determination of basic drying level of a peat production field. Additionally, the utilization of aerial photographs for determination of peat the volumes of peat stockpiles. Suitability of thermal photography for determination of basic drying level of a peat production field was studied by photographing the production field both from an aeroplane and from the ground. Thermal photographing of peat layer was also made in laboratory. Moisture measuring samples were taken from the surface of the peat layer from the depth of 1-2 cm simultaneously with the photographing. On the basis of the research results it has been possible to show the remarkable correlation between the moisture content of the peat surface and the surface temperature when the moisture differences were high (> 20 %). In the case of small moisture differences (< 10 %) no clear correlation was noticed between the moisture content of the peat surface and the surface temperature. The suitability of aerial photography for determination of the volumes of peat stockpiles was studied by photographing 5 stockpiles by recording camera from an aeroplane and by determination of the volumes both photogrammetrically and in the field. According to the results the accuracy  More>>

According to the results the accuracy of volume determination using volume determination from aerial photographs will probably be sufficient for practical purposes. According to the experiences of the autumns 1991 and 1992 it, however, seems that the operational accuracy of recording camera photography in autumn is not, due to the weather, sufficient to ensure the results in agreed time in large-scale stockpile photography}
