NAIP acquires aerial imagery for the contiguous United States (CONUS) during the agricultural growing season, or leaf-on conditions and may contain as much as 10 percent cloud cover per tile. The images are orthorectified which combines the image characteristics of an aerial photograph with the georeferenced qualities of a map. NAIP acquisition from 2002-2017 was at a ground sample distance (GSD) of 1 or 2-meter. In 2018, the ground sample distance standard changed to 0.6 meter with the option for 0.3 meter. The 2025 acquisition consists of approximately half of the states delivered at 60cm and the other half at 30cm ground sample distance. The repeat flying cycle has also changed to no more than a 3-year cycle (generally every other year for most states) from its 5-year cycle back in 2003-2009. Each individual image tile is based on a 3.75-minute longitude by 3.75-minute latitude quarter quadrangle, originally with 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 infrared (red, green, blue, and near infrared bands). These data are a subset of NAIP 2018 covering the extent of the State of Maine with a Spatial Reference System projection in EPSG 26919 USDA FPAC-BC-GEO orthoNaip2018ImgSvc USDA FPC-BC NAIP 2018 20181231 2026-03-05T00:00:00 imageryBasemapsEarthcover orthoimagery ortho USDA NAIP 2018 NAIP 2018 FPC BC USDA https://www.fpacbc.usda.gov/geospatial-services 1 Maine USA Public domain. 20260305 <DIV STYLE="text-align:Left;"><DIV><P><SPAN>Public domain.</SPAN></P><P><SPAN>In no event shall the creators, custodians, or distributors of this information be liable for any damages arising out of its use (or the inability to use it</SPAN></P><P><SPAN>These services are for illustrative purposes only.
