Collection of the unedited GPS track logs recorded during aerial breeding pair surveys using H2 harness. The H2 harness is a data collection device and associated wiring that records voice and position data for use in aerial bird surveys. The H2 replaces the computer program “Record” that was used prior to 2023. The H2 track file has different format than track files from program Record.
Aerial track files (1997 to 2022) collected using the FWS software program “RECORD” (John I. Hodges, MBM-Alaska) running on laptop computers. Program RECORD was activated during the survey before arriving at the first transect and shut down after the last transect was completed, prior to engine shut-down. “Raw” track files recorded the flightpath of the aircraft including the area surveyed on each transect. GPS coordinates were captured every five seconds using a recreational grade receiver with an estimated positional accuracy of 5-10 meters after the software program was activated. These raw track files have not been quality checked, so they may contain missing or erroneous coordinates if the GPS signal was intermittent...
