Raw and comparative topographic datasets collected at Prime Hook (Delaware 19963) between the spring of 2017 and spring 2022. Datasets are broken down into two categories: 1) the collected survey data which includes field data forms, survey photos, .job, .csv, and .shp files. 2) annual comparisons between spring surveys, ie: spring 2017 to spring 2018 etc. The comparative datasets include survey DEMs, difference DEMs, pivot tables, dune and shoreline positions, dune and shoreline change vectors generated through Digital Shoreline Analysis System (DSAS), and additional map items used in the creation of the finished products.
