Portions of other adjacent towns are covered including Belgrade, Chelsea, Dresden, Litchfield, Pittston, Randolph, Readfield, Richmond, Sidney, Vassalboro, West Gardiner, Windsor, and Winthrop. The data were collected in a single session on May 6, 2008. LiDAR data were also collected and are available elsewhere. The 6" imagery is available for the northern part of the area, Augusta and Manchester principally. 1' imagery is for the southern area of the collect. The data were collected and processed by James W. Sewall Co of Old Town, Maine. The LiDAR data were collected and processed by Photo Science, Inc., of Lexington, KY. The scale of 1:7920 was used to produce a mapping scale of 1" = 660'. Purpose: To provide high-resolution recent orthophoto base for municipal mapping applications in Augusta, Manchester, Hallowell, Farmingdale, and Gardiner.

Native_Data_Set_Environment: Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.3.1.1850 Data_Quality_Information: Logical_Consistency_Report: Orthophotos went through a rigorous QAQC process. All data is seamless from one tile to the next, no gaps or no data areas. Completeness_Report: The one foot tiles cover a portion of the area of interest. The six foot tiles will cover the remaining area of interest. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: 45 control points were dispersed evenly throughout the entire area of interest. 26 of the control points fall in the 1' data.
