Service Description: Data sourced from the FROGTECH_NZ_ECS_SEEBASE product in the NZP&M 2013 Block Offer Data Pack.The magnetic grid was generated by FROGTECH from the World Digital Magnetic Anomaly Map (WDMAM) or EMAG3 (2007), a global 3-arc-minute resolution grid of the anomaly of the magnetic intensity at an altitude of 5 km above mean sea level. It was compiled from satellite, marine, aeromagnetic and ground magnetic surveys. Information on this dataset can be found in http://www.geomag.us/models/wdmam.html The TMI magnetic data was Reduced to the Pole (RTP). The RTP image showed numerous noise and artefacts which were further attenuated by applying a Low Pass (20Km) filter. This filter passes low frequencies but substantially attenuates (or reduces) frequencies higher than 20km, emphasizing magnetic anomalies with wavelengths greater than 20km. Caution is warranted
