This point is <br />used to find the error difference in elevation between the GPS and the known surveyed point. This difference will <br />then be applied to all GPS elevation points taken during the inspection for an accurate reading. Predetermined <br />navigation points along transect lines were imported into the GPS and used to take on-site elevation readings. <br />The inspection began at Areas WP019 and WP020 located in the West Pit Reclamation. A total of seven <br />elevations points were taken along this area. The area was well graded and stable. Vegetation was thick and <br />mature with no signs of rills or gullies. Section B- Phase I Bond Release Areas (Map), <br />was inspected. <br />Area WP018 was inspected along Section A- <br />success as Areas WP019 and WP020.
