| Abstract | This report of joint research in progress to evaluate (1) the role and (2) the mapping applications of satellite data for the and Waiotapu geothermal areas.íCombinations of SPOT XS and LANDSAT TM data were evaluated and classification of the data for Waiotapu conducted. Many geothermal features, includinghot pools, sinter terraces, hot bare ground and areas of heat-stressed vegetation were and classified from the large scale colour composite of southern Waiotapu. The results show the key role of the (MIR,1.55-1.75 band 5 for mapping heat-stressed vegetation, which acts as a surrogate for hot ground. multispectral analysis incorporatingvisible, near-IR and MIR bands providesa valuable geothermal technique. At large scales, detailed surveying is also possible. |
