Demonstration Report for Geonics EM-63 Cued-Interrogation Data Collection, Processing and Archiving at Camp Sibert, Alabama
Abstract
This report describes the data collection, processing and archiving of Geonics EM-63 time-domain electromagnetic data over selected anomalies within Site 18 of the Camp Sibert FUDS) In May 2007, cued-interrogation data were collected over 200 anomalies in a blind-test scenario and 38 items in a GPO. The cued-data were collected dynamically along 11 North-South lines spaced 30 cm apart, 3 East-West lines spaced 50 cm apart and on two "pitch" lines directly over the anomaly center. The pitch lines involved collecting data while the EM-63 was pitched backwards and then forwards over the anomaly. In addition to the cued-interrogation, full-coverage data at 0.5 m spacing were collected over the GPO and a 35 m by 60 m area of the blind site. In this demonstration report we evaluate six identified performance metrics for the technology including reliability/robustness, data density, survey rate, percentage of site covered, and position and depth accuracy of inverted positions. Metrics more directly related to discrimination performance are assessed in a separate demonstration report that addresses data processing and interpretation.
