ISRP-PC: A Personal Computer Interactive Survey Reduction Program.

摘要

PURPOSE: To describe the capabilities of the Interactive Survey Reduction Program (ISRP-PC). BACKGROUND: Beach and nearshore profile surveys are required to design and monitor completed coastal projects. Several tools and techniques are available to collect this type of field data such as: boat and fathometer, boat and survey sled, and the Coastal Research Amphibious Buggy (CRAB). Regardless of how the data are collected, there is the need to edit incorrect data points, make datum adjustments, plot the data, and compute volume differences between surveys. ISRP-PC is a powerful and user friendly personal computer program which allows the operator to make these type of corrections and analyze profile survey data. Beach profile survey data can be referenced in terms of cartesian coordinates where Y is the horizontal distance (relative to a baseline) along a transect normal to the shoreline, Z is the elevation relative to a common datum, and X is the horizontal position parallel to the shoreline. The Y and Z components of the cartesian coordinates are manipulated in ISRP-PC. ISPR-PC refers to the spatial position of the transect as Profile Number with a temporal identifier termed Survey Number.
