Paper Abstract

The significance of peat as a local source of energy in district heating and electric power production is increasing in Finland and regular limited aerial supervision of peat stockpiles has been carried out from 1990 onwards. The problems for which thermography and auxiliary methods have been applied are as follows: (1) basic drying distribution of production field, (2) condition of the ditching, (3) volume of peat stockpiles, and (4) supervision of the production area's environment. In 1991 - 1992 we started investigating the possibilities of using thermography, infrared photography, false color video scanning and panchromatic photography in peat production. By increasing the basic drying level of the production field it is possible to accelerate the drying of peat and in that way to increase the seasonal yield considerably. No reliable and viable method is available for a quick analysis of this basic drying level on large areas. Our aim was to find differences in the basic drying level of peat production fields by means of aerial thermography. The tests were carried out in the laboratory, in production fields using field measurements and by airborne infrared scanning combined with simultaneous field measurements. The paper presents preliminary results on the use of thermography in defining the differences in the basic drying level of peat production fields.
