National Agriculture Imagery Program (NAIP) Imagery
공공데이터포털
The National Agriculture Imagery Program (NAIP) is administered by the U.S. Department of Agriculture's Farm Production and Conservation Business Center (FPAC-BC) Geospatial Enterprise Operations (GEO) Branch. NAIP acquired aerial imagery at a resolution of 1-meter ground sample distance (GSD) for the United States from 2003-2017 during the agricultural growing season, or leaf-on conditions. The images are orthorectified which combines the image characteristics of an aerial photograph with the georeferenced qualities of a map. In 2018, the ground resolution standard changed to 0.6 meter with the option for 0.3 meter data was added for consideration over coastal states. The repeat flying cycle was also changed to no longer than a 3-year cycle from its 5-year cycle back in 2003-2009. 2009 to present coverage provides a refresh of every 3-years and less responding to user needs across the United States. Each individual image tile is based on a 3.75-minute longitude by 3.75-minute latitude quarter quadrangle plus a 300-meter buffer on all four sides. In 2024 the buffer was changed to 12-meters on all four sides. Tiles in the NAIP collection are natural color (red, green, and blue bands) or color near infra-red (red, green, blue, and near infrared bands) and may contain as much as 10 percent cloud cover per tile.
