Survey Size:
Alaska Peninsula

Alaska Peninsula

Approximately 7,000 square miles; 1,609 helicopter stations from EDCON’s Bristol Bay Survey, 908 stations from the USGS gravity data base, 3,013 helicopter stations from the Strata Search survey.

Data Spacing:


Terrain Corrections:

Through Hayford-Bowie Zone J

Project Summary:

USGS stations have been terrain-corrected and integrated with the EDCON and Strata Search data. If Strata Search data are not owned, the EDCON/USGS data are available as a separate integrated package. Editing performed during hand-contouring has produced high-quality Bouguer gravity maps.

Data Provided:
  • Bouguer Gravity Map (scale 1:96,000): Gravity data are tied to the Worldwide Defense Mapping Agency base station gravity network.
  • Magnetic tape and computer printout containing all principal survey facts including: station number, date surveyed, latitude, longitude, UTM X-coordinate, UTM Y-coordinate, elevation, terrain correction, station gravity, free-air gravity and Bouguer gravity calculated with three densities
  • Reports
