收藏资源简介:
Image Service | OGC WCS | OGC WMS | KMZ | Tile Download Maine Statewide Orthoimagery Project. All imagery was collected during the 2013 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.
