The Significant Geothermal Feature data is a combination of information digitised in-house, and data received from Wildlands Consultants regarding vegetation and other sources regarding geophysical aspects of Significant Geothermal Features. This particular layer represents Significant Geothermal Features as in the Regional Plan Geothermal module. December 2006: Some boundaries have changed; the features are based on Wildlands 2004 work that was reflected in the Decisions version and the recent fieldwork undertaken by Wildlands in late 2006. Changes were made ONLY where boundaries could be reduced in specific area, to satisfy Environment Court requirement that only areas notified publicly be shown. April 2011: Some boundaries have been changed, and maps for Tokaanu and Atiamuri added. Hydrothermal eruption craters on the Horohoro map have been added. Some warm streams have been added. Information was collected and checked using WRAPS aerial photography.For further metadata please see feature WRP_GEOTHERMAL_FEATURE_20M in dataset Waikato Regional Plan Significant Geothermal Feature
