Description

This is local version of the USGS National Map aerials which are based on the National Agriculture Imagery Program (NAIP). The Southern portion of the map (NJ,PA,DE,CT,RI MD,VA,WV) was downloaded in May, 2023. The Northern section of the map (NY,MA,NH,VT,ME) was downloaded in April, 2024. Download dates notwithstanding, the actual imagery is clearly older than 2023. According to wikipedia, the USDA considered eliminating free access to NAIP imagery in a 2018 proposal. Under this proposal, NAIP would no longer offer free imagery after 2019. There was also discussion of limiting future aerial photography to agricultural lands only instead of the entire US. It is unclear whether any of these changes have been adopted, but it is notable that 2019 is the newest imagery available for direct download from NAIP. So, most likely, the imagery in this map is no newer than 2019.

The original imagery was acquired at 1 meter resolution in "leaf-on" (eg: summer) conditions. This map has a resolution of 8 feet (2.4 meters) however, as this is the maximum available from the USGS National Map seamless dataset. Collection of NAIP imagery is administered by the U.S. Department of Agriculture's Farm Service Agency (FSA).

The map includes full coverage of New Jersey, New York, Pennsylvania, Maryland, Delaware, Connecticut, Rhode Island, Massachusetts, New Hampshire, Vermont and Maine with partial coverage of Virginia and West Virginia.
