Accurate surveys and adequate maps are essential for planning, design, and construction of channel rectification and other works for a major river project; to insure the complete project it is necessary to safety perform functions intended in design and purpose. A complete analysis of the approach to the project survey and mapping requirements is necessary. What accuracies, methods, instruments, scales, and contour intervals are needed to provide the data required? Priorities for areas or data must be established. Effective plans must be made for such items as aerial photographic scales, flight direction, type of camera, location, refinement and density of ground surveys, map scales and contour intervals, logistics, and numerous other items. After these decisions are made, effective plans are accomplished for the preliminary survey and mapping for engineering and design, construction survey, and post-construction survey. Without proper planning for all phases of a project, including the use of modern techniques and high accuracy standards in surveying and mapping, costly delays are likely to occur.
