To provide accurate orthorectified imagery covering the Town of Fort Fairfield. The seamless presentation is available to Maine GIS users through direct connection to the MEGIS Oracle/ArcSDE database, to anyone with Internet Browser access for viewing through an Internet ArcIMS application at http://megisims.state.me.us/website/orthomap/viewer.htm and for free download from the Maine GIS Internet Data Catalog.
ORTHO_FF orthophotography of Fort Fairfield, Maine compiled by Bradstreet Consultants, Inc. in the year 2003. Features were collected from aerial photography taken May 20, 2003. Airborne GPS, IMU, and ground control were all used to control the project. All features were compiled in Kork Digital Mapping System then translated using AutoCAD to files for use in ArcGIS. The orthophotography in ORTHO_FF has a ground spacing value of 0.15 meters or 1/2 foot GSD and provide a digital photographic map suitable for applications requiring a 1:1200 National Map Accuracy Standard (NMAS).

Users must assume responsibility in determining the usability of this data for their purposes. Digital maps retain the accuracy of their source materials. The best use of data mapped at scales of 1:500,000 and 1:250,000 is in statewide planning and studies; at 1:100,000 in regional planning and studies; at 1:62,500 and 1:24,000 in detailed studies and local planning; and at 1:12,000 and 1:5,000 or larger scales in parcel level studies and detailed local planning. In the use of Maine GIS data, please check sources, scale, accuracy, currentness and other available information. Please confirm that you are using the correct copy of both data and metadata from the Maine GIS Data Catalog. Updates, corrections, and feedback, incorporated in the Maine GIS database are made in accordance with "Data Standards for Maine Geographic Information Systems", 2002, and coordinated by MEGIS

ORTHO_FF is available from Maine GIS in three presentation formats. First as a seamless mosaic of the original images in .TIFF format stored in Oracle 9i for users of ArcSDE, second through the Maine GIS ArcIMS ORTHO viewer at http://megis.maine.gov/maps/ and third, TIFF images in MrSID compression format, available for free download from the Maine GIS Internet Data Catalog. The image names of the MrSID files were created with the same 10 digit numeric designations originally assigned by the vendor. Both ArcExplorer 4.0.1 (free for download from http://www.esri.com/software/arcexplorer/index.html) and the ArcGIS 9.x module ArcMap accept a URL for "adding" data from an Internet location.
