Scientists who study coastal ecosystems and hazards such as hurricanes, flooding, and cliff failure collect lots of photographs of coastal environments from airplanes and drones. A large area can be surveyed at high resolution and low cost. Additionally, satellites such as Landsat have provided imagery of the Nation’s coastlines every few days for decades. Scientist’s ability to understand coastal hazards would be greatly improved if this wealth of imagery could be ‘mined’ automatically by computers. We want to automate the process of identifying and labelling each region of the image from a set of categories (e.g. bare land, water, woody vegetation, herbaceous vegetation). We need to train a computer to recognize...

These data consist of down-looking images of Lake Michigan benthos, collected in 2020 and 2021 with an autonomous underwater vehicle (AUV). Information about each image (i.e., latitude, longitude, depth from surface, altitude, roll, pitch, yaw, and creation time) can be found in the associated csv file. Substrate type was divided into 9 classes based on the Coastal and Marine Ecological Classification Standard (CMECS) and each image was assigned a substrate class by at least 3 trained labelers.

This data release presents structure-from-motion (SfM) products derived from aerial imagery collected along the North Carolina coast in response to storm events and the recovery process. U.S. Geological Survey (USGS) researchers use the aerial imagery and products to assess future coastal vulnerability, nesting habitats for wildlife, and provide data for hurricane impact models. This research is part of the Remote Sensing Coastal Change Project. Products include digital elevation models and orthorectified imagery (RGB-averaged products) created from aerial imagery surveys with precise Global Navigation Satellite System (GNSS) navigation data flown in a piloted fixed-wing aircraft. The products span the coast over...
