Info

. 1. Base station data were manually edited for cultural interference. 2. A ‘height correction’ based on IGRF was applied to account for height deviations from drape. 3. IGRF was removed after levelling. 4. Corrugation still remains between ties after tie-line levelling. As a result, two passes of micro-levelling were used. Both passes use a variable clip to minimize filtering in areas where intersection levelling is effective. In pass 1, the degree of micro-levelling is limited by altitude deviation from drape, while pass 2 is limited by the relative activity of the block, using the analytic signal of mreslvl. See Table I below for processing parameters. 5. IGRF is calculated at a fixed average survey height on a fixed date (Table I).
