290 This work was carried out in London during June 1985 (Stove, 1985) with the aim of identifying leaking water mains, sewer collapses end piperuns below the pavement surface. The main conclusion from this work was the complementary nature of the two systems since the impulse radar provides information relating to the depth of features beneath the terrain, that is in the vertical plane, whereas the TVFS provides date about the spatial extent of the phenomenon in the horizontal plane. For example, at one particular sewer site the ground impulse radar indicated a marked discontinuity between the structure of the road and the fill materiel beneath; normally this is indicative of poor compaction or voiding in this zone. Also, a reduction in the radar signal velocity occurred which indicated that the material in this zone was of a much higher moisture content then the surroundings. Analysis of the TVFS imagery over the same area was carried out by density slicing the thermal emissions to indicate l°c temperature intervals. A clear indication of the size of the sewer was obtained and a marked increase in emission was detected corresponding to the discontinuity recorded by the ground impulse radar. The work on this particular application is at an early stage of development and a method of automating the measurement of any correlation between the data from these two complementary sensors is currently being considered. One possible solution may be to reformat the output from the ground impulse radar and record this on videotape (Stove, 1985). The radar data could then be digitally formed into image form and registered with the TVFS date. 6.5 Further Applications In addition to the projects outlined above TVFS systems have potential application for many other environmental engineering projects including: oil pollution monitoring, monitoring of spontaneous combustion of waste tips, power station cooling water discharge monitoring, ground water and spring detection and hydraulic leakage from dams. 7 CONCLUSIONS TVFS systems differ considerably both in optical design and in radiometric characteristics from thermal linescanning instruments. A wide range of instruments are currently available using distinctive imaging techniques. Such instruments provide an alternative method of acquiring thermal data and, in general, at lower cost, if a light aircraft is used as the measuring platform. By using suitable image processing techniques and ground temperature measurements for calibration purposes quantitative thermal characteristics of the terrain can be deduced. It is suggested that TVFS systems have a significant role to play in the acquisition of thermal data for environmental engineering projects particularly when used in conjunction with other complementary remote sensing or geophysical sensors. 8 ACKNOWLEDGEMENTS The authors wish to thank the following organisations and individuals for their assistance with this project; Barr and Stroud Ltd, University of Surrey Research Committee, Professor G.
