Robinson 2026 publication The US Geological Survey's Upper Midwest Environmental Sciences Center, in coordination with the US Fish and Wildlife Service's (USFWS) Branch of Migratory Bird Surveys, worked to develop, survey, and deploy an advanced aerial photography boresight in the town of Bassville Park, Florida. The intention of this boresight is to provide an extensive array of high-accuracy ground control points, to supplement an existing lidar boresight at the site, for the development of camera metrics on novel camera systems managed and deployed by the USFWS. This layer provides survey data for high-accuracy ground control point data collected in Bassville Park, Florida to be used in the calibration of aerial photography systems.

La Crosse WI 54603 US 608-781-6386 608-783-6066 astrassman@usgs.gov This project was funded through a collaborative agreement with the US Fish and Wildlife Service's (USFWS) Branch of Migratory Bird Surveys. No formal attribute accuracy tests were conducted. A visual inspection of the data set values was performed and found to be accurate. No formal logical accuracy tests were conducted. A visual inspection of the data set values was performed and found to be logically accurate. Data set is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. A formal accuracy assessment of the horizontal positional information in the data set has not been conducted. A formal accuracy assessment of the vertical positional information in the data set has either not been conducted or is not applicable. Paul H. Rydlund, Jr. Brenda K. Densmore 2012 publication https://pubs.usgs.gov/tm/11d1/ Digital and/or Hardcopy 20210921 publication date Rydlund and Densmore 2012 Methods for site-level data collection The area of Bassville Park, Florida was reviewed for an area of 2-mile x 2-miles that coincided with developed areas with sufficient, permanent ground infrastructure for selecting and surveying up to 10 ground control points per quadrant and maximum coincidence with an existing lidar boresight in the area. A cardinal direction aligned square was selected centered on 28.8384173 degrees north and 81.7821316 degrees west. This square was divided into 16 1/2-mile by 1/2-mile squares with these squares named FA1 - FD4 with east-west rows designated 1-4 (north to south) and north-south columns designated FA-FD (west to east) such that the northwest quadrant is FA1 and the southeast quadrant is FD4. 20241218 Each quadrant was reviewed for potential ground control point (GCP) locations using the available Esri ArcGIS Pro basemap aerial imagery and other ground level imagery from Google Maps and Google Earth. 10-15 GCP sites were chosen in each quadrant, labeled, and prioritized. Sites were selected based upon a clear signature in the available imagery, a clear overhead space (lacking trees and buildings), and potential for long-term feature stability (e.g. permanent manmade infrastructure). Prioritization was based upon potential number of overlaps of the site during a hypothetical boresight imagery collection by the US Fish and Wildlife camera system with priority given to sites with the maximum number of independent collections of images of the GCP. Additionally, sites with the highest priority were designated for collection at level 2 accuracy with the remaining sites designated for collection at level 4 accuracy (per Rydlund and Densmore 2012). Rydlund and Densmore 2012 20241218 Ground control point data were imported from the final tabular data file into an Esri geodatabase. The geodatabase was set to a horizontal projection of NAD 1983 (2011), Florida East Zone state plane meters and a vertical projection of NVAD88. Data accuracy and table integrity were confirmed and then data were exported to an Esri shapefile format with the same coordinate systems. Rydlund and Densmore 2012 20250116 Final tabular data from the field data collection were reviewed for errors and consistency. The quality of each level 2 collection location was reviewed to determine if it met the criteria for a level 2 collection as defined in Rydlund and Densmore 2012. Of the 115 ground control points collected, 27 had blunder checks collected and of these 7 failed their blunder check. Final results were 20 points at Level 2 and 95 at Level 4. The highest horizontal error was 0.039 meter and the highest vertical error was 0.079 meter.
