RESPONSIBILITIES A.- SCOPE Project Area Our understanding of the Project area is Denton County, Texas in its entirety A 133 square mile area around the City of Denton is mapped with higher resolution and accuracy Aerial Photography MAPXC U will acquire new vertical color aerial photography covering the above mentioned Project area Photography will be exposed with a precision 6" focal length mapping camera at a negative scale of 1"=2500' for the entire County Consecutive photographs in each flight line shall have an average forward overlap of 60 percent Sidelap between adjacent parallel flight lines shall have an average 30 percent In addition to the mapping photo coverage described above, MARKHURD vv ill also obtain larger scale color photography of the City of Denton area This photography will cover the area indicated on the attached Project area map at a negative scale of 1"=1667' Color digital orthophotography will be produced from this imagery Important Note Under haze conditions, color imagery becomes more difficult to obtain the lugber the flight height MARKHI.TRD does not recommend color photography at photo scales higher than 1"=1667' (flight height >10,000' above ground level) The higher the flight, the more light scatter in the atmosphere resulting in blue imagery We can adjust to haze conditions for black & white photography by using a yellow filter on the camera lens and with different paper in the photo lab These mitigation methods are not available for color Geodetic Control MARKHURD will establish all horizontal and vertical control necessary to perform the mapping services described herein using airborne GPS techniques Horizontal control will be based on the Texas NAD 83 state plane coordinate system Vertical control will be based on mean sea level A minimum, of six (6) ground control points will be established on photo identifiable positions for quality control purposes Permanent monuments will NOT be established Analytical Aerotriangulation Upon completing the control survey task, MARKHURD will prepare a fully analytical aerotnangulatioa solution to establish supplemental control for orienting individual photogrammetne stereo -model's covering the subject Project All field control locations and pass points will be measured on a set of scanned film diapositives using our Intergraph Z-III softcopy stereoplotter The results vvzll be processed using'.v1ATCH AT Aerotriangulation software 2 Copynahf 1997, by ALARKi4DRD Digital Elevation Model Once the analytical triangulation is complete, MARKHURD personnel will compile a digital elevation model (DEM) which will consist of a series of masspoints (x,y,z) and limited breakline files across the entire Project area This data will be processed into a TL' file for use with our ortho rectification software 5' Contour Option It will be possible to capture enough mass points and break lines to provide 5' contours for the City of Denton area from the 1"=1667' photography Since photography, control and aerotnangulation is necessary for the ortho rectification process anyway, any area within Denton can be contoured and priced on a area by area basis, at any future date, if desired Digital Orthopbotography It is MARI{HURD's experience that starting with consistent quality imagery is one of the most important procedures that can take place towards eliminating problems that could occur during the various digital ortho production phases As such, NIARKH RD will begin the orthophotography production with an intensive analysis of the aerial film negatives Quality checks will be performed so as to insure that any problems areas are identified and prior to producing a set of diapositives for scanning MARXHURD will work closely with the Client during this initial process so as to clarify the specific needs and expectations of the digital ortho product A separate set of film diapositives vnll be produced and used as input to the scanning process In order to produce the highest quality digital ortho product, these diapositives will not be handled or used in any other production process prior to scanning Image Capture MARKI-NRD will utilize a Zeiss PHODIS Image Scanning System to capture the analog aerial image in raw digital format The Zeiss PHODIS has exceptional geometric accuracy as well as many other significant features essential in creating high quaLty imagery The film diapositives mentioned above will be scanned at a resolution of 14 nucrons (approximately 2000 dots per inch) which will yield the 2' and 1' ground resolutions for 2500' scale and 1667' scale photography respectively Since the delivery format is MrSID and this is a seamless format, the data will not be broken into tiles Final Edit To ensure that all data is correctly formatted and geo-referenced, the files will be interactively examined on a high speed )vorkstation by a digital ortho specialist This will be in addition to the numerous computenzedchecks performed by M-ARKHURD's p:opnetary and ISM software DELIVERABLES Items to be delivered under this proposal are ➢ Color Digital orthophotography will be delivered on CD-ROM in MrSID format ➢ Digital Elevation Model (not suitable for contours) in format lobe defWCd, Cop)n1h11997, by AL{R NZ7D A. p2OJECSCHEDULE MARKHURD has the resources to meet the most dema_*idmg of schedules Nonetheless, the time required to deliver the items described in Part I B above are subject to being influenced b) numerous factors (i e weather, Client schedules/budgets, scenario selected, etc ) some or all of which may be beyond MARKHURD's control Therefore, we propose to develop and famish a mutually agreeable Project schedule, after an agreement between our organizations (regarding the

resolutions of 14 microns are required for our softcopy aerotnangulationinethodology .C. FUTURE UPDATES A major advantage of digital ortho imagery is the ability to seamlessly update on an as need basis Where ever the County defines areas of change, a photo mission can be designed to capture only those areas These small areas are controlled from the previous project imagery and ortho rectified to an updated DEM The imagery is then simply patched into the existing files It will be possible to der elop 5' contours anywhere in the Cary of Denton area Nvithout hav ng to add control or re -flights except in areas of change P ASS TIb/PTIONS/GONDII2=0NS This Proposal is subject to the following assumptions 'conditions MARKSURD's cost estimate, is in part based on the assumption that the Project Area as 00pnl?QO he101n, 15 accurate This is your notice that our cost estimate is a firm figure only when this assumption is valid Therefore, it is the Che6U responsibility to review the Project Area for exactness (outlined on the document mentioned in Part I A "Project Area") and notify 4 Copyright 7997, by bLAXW EIRD MARKHURD of any changes prior to the execution of an agreement between our organizations E. %2EPRF.;ENTATIVE John F Bloodgood, P L S , Vice President, and Bob Seaberg, P L S , Project Manager, will represent MARKHURD during the performance of the services to be provided under this proposal Each has the authority to transrrut and receive instructions, and make decisions with respect to the services Mr Seaberg is authorized to commit the necessary resources towards completing the services described herein 5 Copynyhi 1997, by M&RMURD PART II CLIENT'S RESPONSIBILITIES Client, at its expense, shall do the following in a timely manner so as not to delay the services to be performed by MARKHURD F.
