Some geothermal areas are largely covered by vegetation, making exploration and monitoring a difficult and expensive task. Therefore, looking for pathfinders/proxies in typical vegetation cover could reveal information from the hydrogeological system remotely. Buffering is a commonly used proximity technique for spatial analyses in remote sensing. Aiding to reduce the possible inaccuracies of geolocation. Variable distance isotropic buffers were utilized to extract data from a combination of different spectral images covering Waiotapu Geothermal Field in New Zealand. Correlating them with the antimony concentration of sampled kanuka plants in the Field, through a PLSR (Partial Least Squares Regression).
