Efficient Hydrographic Survey Planning Using An Environmentally Adaptive Approach

摘要

This paper examines the impact of adaptive line running on survey planning. Since the progression of an adaptive survey, i.e. the shape and position of the track lines, depends upon the topography and other factors, simulations must be used to estimate survey time. We see that the introduction of adaptive surveying can complicate this process due to sometimes dramatic differences in survey time estimates depending upon the alternatives chosen to execute a survey. A brief introduction is given to an implemented adaptive survey approach and a simulator developed for making survey time estimates. Results of simulation time estimates for a US Northeast coast survey are presented that reveal some of the unexpected dependencies that exist with adaptive surveys. Finally, a closer examination is provided regarding how user specified survey parameters may impact overall survey time.
