horizontal control is required and has determined <br /> no additional control is required. The North <br /> Carolina Geodetic Survey sets the required <br /> horizontal ground control using Global Positioning <br /> System (GPS) equipment for the services and <br /> products to be performed by the Company. The <br /> total cost for this phase is $14, 000 . <br /> Phase C . Fully Analytical Aerial Triangulation (FAAT) : <br /> FAAT to properly control the mapping project will <br /> be produced as described in the RFP. The Company <br /> will produce new FAAT to use in the projections of <br /> the orthophotos . Old FAAT will not be used to <br /> produce the new orthophoto base maps . The total <br /> cost for this phase is $38, 400 . <br /> Phase D. Production of Digital Orthophoto Base Maps : The <br /> orthophotos will be based on NAD 83 and will show <br /> corresponding NAD 83 and NAD 27 grid ticks at the <br /> four corners of each map sheet . The total cost <br /> for this phase is $67, 915 . <br /> Type of Map Number of Sheets by Map Scale Total <br /> Digital Orthophoto 1"=100 ' 1"=200 ' 1 "=400 ' <br /> Area Maps (400) (90) (88) (578) <br /> Entire County (132 ) (132 ) <br /> Digital Orthophoto Standards : The digital <br /> orthophotos will be produced and clipped to the <br /> modular map sheet boundaries (2 , 500 ' x 2 , 500 ' for <br /> 1"=100 ' scale, 5, 000 ' x 5, 000 ' for 1 "=200 ' scale <br /> and 10, 000 ' x 10 , 000 ' for 1 "=400 ' scale) . Images <br /> will not extend beyond the modular sheet <br /> boundaries . The methods used in the production of <br /> the digital orthophotos, the types and <br /> specifications of the equipment to be used (e.g. , <br /> the DPI and the geometric accuracy of the <br /> diapositive scanner) , the accuracy and ground <br /> pixel resolution of the finished digital <br /> orthophotos, and the media, file size, and format <br /> to be used in the delivery of the digital <br /> orthophotos to the County will be as described in <br /> the proposal . The County currently has ARC/INFO <br /> GIS software. The Company agrees that the County <br /> will need no additional software or hardware in <br /> order to store, display or manipulate the digital <br /> imagery. <br /> Phase E . Topography: The production of digital topography <br /> will be produced and based on the same scale as <br /> the digital orthophotos (see Section 1 . 0 Project <br /> Overview of the RFP) and will result in the <br /> creation of a Digital Terrain Model (DTM) of <br /> 2 <br />
