White Company is pleased to present the following proposal for certain photogrammetric and survey services. Alternate 1, FEE: $25 ,500.00 SCHEDULE: As per specifications, weather and snow cover permitting , provided we receive notice to proceed by December 30 , 1971. • Alternate 2. FEE: $44,500. 00 SCHEDULE: Priority 1 - 2 weeks late-March 15 , 1972 Priority 2 - 2 months late-May 31 , 1972 Priority 3 - 2 months late-June 30, 1972 with above provision.

No. 3 (a) of Specifications , and No. 1 of letter of December 13, 1971. Strike out word "composite" , contours are to appear only on pencil manuscript. Page 5. Sec, B. No. 1 (b) . If selected we will fly to obtain new photography at a nominal negative scale of 1"=1200 ' , and/or 1"=1000 ' . Compilation and cross sectioning of the smaller scale will be done on a Wild A-7 Autograph. Page 6. Sec. C. No. 1 (c) . As above, for mapping scale 1"=200' . r 1"=600 ° and/or 1"=500 ' for mapping scale F '' of 1"=100 ° , with compilation and cross sectioning of the smaller scale to be done on Wild A-7 Autograph. Page 7 . Sec. C. No. 2 (a) . Coordinate system will be on State Plane Coordinate System, and field survey will be augmented by aeropolygon triangulation using a Wild A-7 Autograph for supplementary control, i.e. 6 x,y,z control points for each stereo model. Rebars will be placed on field occupied 1 horizontal stations , and survey control ( sketch and control tabulation will be supplied. Page 7. Sec, C. No. 3 (a & b) . vL V Read: Part II, Section A, 3. (1 & 2. ) . Page 8. Sec. C. No. 4 (a) . Horizontal accuracy of 1/40th inch to apply to pencil manuscripts only. Film positives J V will be carefully scaled and rectified to points on the valley floor to obtain a good mean solution, fl . EL.1 Mr, Edward S. Kelly -3- December 15 , 1971 Letter of December 13 , 1971. No. 1 "significant features" . In areas of sparse detail, we feel this could be such items as fences or field lines , besides roads and I drainage. In built up areas we feel it would be unnecessary to show every street , but to adopt a pattern of detail sufficient to orient the film positive to the manuscript. General An index will be provided showing relationship and numbering system, between manuscript, film positive, and cross section overlay. There is \ little or no adaptibility of sheet size or \ \ uniformity of sheet alignment provided for in \ this proposal. A preliminary layout for the 1 1 1"=200 ' scale indicates approximately 26 / manuscripts and matching cross section overlays , and 49 film positives. f- t1 N As an optional feature , if the cross section C,°' \ overlay were eliminated, and the cross sections i shown on both the pencil manuscript and the film positive, it would serve as an aide to orientation of the sheets , and result in a cost reduction of material as follows : Alternate A-$300 Alternate B -$700 we thank you for the opportunity to be of service to you on this project.
