Uncrewed aerial system aeromagnetic test survey at the Boulder Magnetic Observatory
This data release contains two related datasets acquired for the uncrewed aerial system aeromagnetic test survey at the Boulder Magnetic Observatory. The first contains the raw magnetic data for the set of four test flights, and the second contains the compensated magnetic data for the same four flights. Details of the data are recorded in the metadata files associated with each dataset.

This publication provides digital flight line data for a high resolution magnetic and radiometric survey over an area of central Idaho, USA. The survey includes airborne geophysical data collected as part of the U.S. Geological Survey (USGS) Earth Mapping Resource Initiative (Earth MRI) effort (Day, 2019). Earth MRI is a cooperative effort between the USGS, the Association of American State Geologists, and other federal, state, and private sector organizations to improve our knowledge of the geologic framework of the United States. Data for this survey were collected by Sander Geophysics Ltd. under contract with the USGS using a rotary wing aircraft with a magnetometer mounted in the forward stinger and a fully...

These datasets contain the processed data for four very low-altitude, repeat uncrewed aerial vehicle aeromagnetic surveys over a test site located at the Boulder Magnetic Observatory near Boulder, CO. The surveys span an area of approximately 150 x 150 m, with the central area of 100 x 100 m as the primary focus of the investigation. These data were acquired September 25, 2019, by Juniper Unmanned, working under contract to the U.S. Geological Survey. The nominal flying heights were 25 and 40 m. Flight lines were spaced 8 m apart and directed north-south; tie lines were spaced 24 m apart and directed east-west. A total of approximately 8 line-kilometers were acquired.
