Lineations within and boundaries between areas of similar electromagnetic anomaly are identified as line features and described in terms of their type and defining characteristics. Ancillary information is provided about the survey and image type and processing. This data layer contains interpretations of three different frequency (1800 Hz, 40 KHz and 8200 Hz) domain electromagnetic variants from the Glass Earth geophysical survey undertaken in 2007. The data layer is part of the 'Geology of the Middlemarch area' 1:50 000 dataset covering a part of of East Otago around Middlemarch township.
