Tile Download Link This is an orthoimagery collect for the City of Lewiston from 1997. The imagery are 8-bit panchromatic orthorectified aerial photos. The data were collected in a single mission on May 5, 1997 for a mapping scale of 1"=600' and have a pixel resolution of 6" (0.15m). Accuracy would be similar to ASPRS Level 2 (+/- 24")

Lewiston/Auburn 2006 3" orthoimagery - As the prime contractor, James W. Sewall Company. used the aerial photography flown in one session on April 9th, 2006. Data were collected at an altitude of 7200' using a 6" Zeiss RMK camera with FMC. The film scale was 1" = 600', scanned at a resolution of 2540dpi (10 microns). Orthophotos were produced to meet ASPRS class 1 specifications for 1"=100' (1:1200) mapping, or a horizontal accuracy of about 1 foot with a 3-inch ground pixel resolution.

Tile Download Link Maine Statewide Orthoimagery Project - All imagery was collected during the 2018 Spring flying season during leaf-off conditions for deciduous vegetation in the State of Maine. The sun angle was at 30-degrees or greater, and streams were within their normal banks. During the flight planning and acquisition, a significant effort was made to limit clouds, snow, fog, haze, smoke, or other ground obscuring conditions in the imagery. In no case does the maximum cloud cover exceed 5% per image. Within the immediate areas of power plants, factories, or controlled agricultural burns some steam or smoke and/or shadows may be visible on imagery. The Maine GeoLibrary Board has developed a statewide, 5-year, rotating orthoimagery acquisition program for Maine to facilitate state, regional and local government GIS base mapping in an efficient and cost effective program. The State of Maine will use digital orthoimagery for the development of various base map products in a computerized GIS that will support the needs of the state and multiple stakeholders through applications, such as, multi-jurisdictional homeland security mapping applications, state and county emergency management applications, regional and local planning, state and local public safety applications, economic development and other GIS business objectives.
