These data contain observation and null polygons for waterfowl aerial surveys of Lake Michigan collected through the years 2009-2014. Polygons were created adjacent to either side of the flight lines (transects). The right and left offset of the polygons from the flight path, was determined using the average altitude of the plane along the transect and the observation angle through the plane’s window. Observed birds were counted and identified by species. This count data was attributed to the polygon closest to the point along the transect where the observation occurred, and on the side of the plane in which the observation took place. The point data represent counts where each point represents a single species....

This dataset is a collection of cropped avian images that pair with species identification annotation values.

Thermal imagery was collected over the Platte River in Nebraska on March 20 and 21, 2018. The sensor used was a FLIR A8303sc midwave thermal sensor (FLIR Systems, Inc., Nashua, New Hampshire) with a 50 mm diameter lens.

The aerial imagery contained in this mosaic was collected on July 17, 2014 with an Applanix 439 Digital Sensor System. These missions were flown at 6"/pixel and 8'/pixel resolution. These mosaics complement the land cover land use data by providing an image format to consider. A flight plan was not used and this resulted in incomplete coverage. The area of interest is the Crane Creek estuary in the Ottawa NWR and the mosaic is for the purpose of habitat monitoring.

The color infrared aerial imagery contained in this mosaic was collected on July 17, 2014 with an Applanix 439 Digital Sensor System. The mission was flown at ~4,000 ft. above ground level resulting in a ground sample distance of 0.20 meters (8")/pixel. The area of interest is the Crane Creek estuary in the Ottawa NWR and the mosaic is for the purpose of habitat monitoring.
