Liberty Bell area, western Bonnifield mining district, electromagnetic and magnetic airborne geophysical survey, data compilation

This publication, GPR 2017-1, provides geophysical data produced from an airborne geophysical survey conducted in 2001 and released in 2002 for 276 sq miles of the Liberty Bell area, western Bonnifield mining district, central Alaska. Aeromagnetic and electromagnetic data were acquired during the survey. During 2016, the same digital data were reformatted for ease of use with modern processing tools; vector shapefiles and the analytic signal and calculated first vertical derivative grids were added. Other than the creation of calculated grids, no new processing was done. Data provided in GPR 2017-1 include processed (1) linedata ASCII databases, (2) gridded files of magnetic and resistivity data, (3) vector files...

Fodar Orthomosaic of the Totatlanika River Corridor (Alaska) Acquired August 2021

This dataset provides an orthorectified aerial photo mosaic derived from airborne fodar data acquired in 2021 on August 31 over the Totatlanika River in central Alaska. The term “fodar” is a portmanteau of foto and lidar, coined by Matt Nolan, which describes a method of quantifying the color and elevation of Earth’s surface via airborne small-format digital camera photography.
