Summary

This point cloud was derived from low-altitude aerial images collected from an unmanned aerial system (UAS) flown in the Cape Cod National Seashore on 1 March, 2016. The objective of the project was to evaluate the quality and cost of mapping from UAS images. The point cloud contains 434,096,824 unclassifed and unedited geolocated points. The points have horizontal coordinates in NAD83(2011) UTM Zone 19 North meters, vertical coordinates in NAVD88 meters, and colors in the red-green-blue (RGB) schema. The points were generated in photogrammetric software (Agisoft Photoscan Professional v. 1.2.6) from 1122 digital images taken approximately 120 m above the ground with a Canon Powershot SX280 12-mexapixel digital camera mounted in a [...]

Purpose

The purpose of generating and releasing this point cloud was to provide a basis for additional products (digital elevation maps and orthophoto mosaics) and for use in researching methods of automatic point-cloud classification. The broader goal of the project was to evaluate the quality of images and photogrammetric products and evaluate the cost and feasibility of mapping from UAS images.
