The numbering system shown on the map corresponds with GIS project files and existing map sheets, and should be used for identification wherever practical in this project. Control Surveys To perform accurate photogrammetric measurement, horizontal and vertical survey data will be required at numerous locations in and around the project area. These control points must be identifiable on the aerial photography and must be in strategic locations with respect to the flight lines and stereo -models. This is a critical element to the accuracy of the mapping and will serve as the foundation for the horizontal and vertical map datum. This portion of the project will be under the direction of Gordon Perry of Carter Burgess. All control points will be pre -marked (targeted) to insure visibility on the photography. It is also important that the points are located in clear areas to allow an unobstructed view for GPS occupation and satellite reception. For controlling the Project area, approximately 500 points will be required. Prior to obtaining the aerial photography, field reconnaissance and targeting will be performed. The targets will be placed as an "X" with each leg 4' long and 1' wide with the control point in the center. Each target will be placed on natural ground surface and secured with nails and shiners. All point locations will be on public land if possible and set with a %Z" iron rod and plastic cap. The ground control surveying will begin with the location of National Geodetic Survey (NGS) monuments found in and around the project area. The coordinate systems will be established based on a minimum of four horizontal NGS monuments and four vertical NGS monuments. Eight (8) to twelve (12) permanent control monuments will be set around the project area in locations approved by the City of Lubbock. Before beginning permanent monumentation, the Contractor will provide a description of the monumentation technique for approval by the City. These monuments are needed to establish coordinate values for all aerial panel points required for the project. A "Static" Global Positioning System (GPS) traverse loop will be run starting from the NGS monuments found traversing through the permanent control monuments set and ending back on the NGS monuments. This loop will produce second -order accuracy for the permanent control monuments. The 475 to 500 aerial panel points needed for the project will be set and located using "Real Time Kinematic" (RTK) GPS. Each RTK GPS location will have an independent verification to ensure second order horizontal precision and a vertical error not to exceed 2 centimeters (0.06' or 3/4"). While the published accuracy specification for RTK GPS P. 10 is plus or minus 1 centimeter (0.03'or 3/8'). Carter Burgess's experience shows that 2 centimeters is a worst case scenario; proper application of the GPS technology allows Carter Burgess to achieve results generally between 1 to 1 %i centimeters. In addition, Carter Burgess will run a third independent verification on 20 percent (20%) of the total number of aerial panel points set by occupying random panel points as it moves its RTK GPS base station around the control monument network. Reference sketches will be created for all NGS monuments found, control monuments set, and all aerial panel points set. These sketches will be incorporated into the final report and forwarded to the City of Lubbock. A digital file showing the location of all control points will also be provided on a digital map of the project area. The digital map will be provided by the City. Independent databases will be created for the NAD 27-NGVD 29 and NAD 83-NGVD 88 datums. All points will be computed in both databases to ensure accuracy of the point locations. A single scale factor will be developed for the project area so that future work can be added. NAD 83-NGVD88 grid coordinates will be forwarded to Dallas Aerial Surveys, Inc. A final report will be generated explaining how the control network was established, the results of the "Static" GPS surveying, procedures, and results of the "RTK" GPS surveying, how the project scale factor was derived, a listing of coordinate values in both datums of all points surveyed, and copies of all reference sketches for all surveyed point locations. Processing all control points utilizing aerotriangulation procedures insures quality control. Any point that does not fall within specifications is noted and flagged for re- occupation. Aerial Photography To produce the desired maps and photo products, Dallas Aerial Surveys, Inc. will obtain new black -and -white aerial photography at two scales: 1"= 400' (2,400' above terrain) and 1"= 800' (4,800' above terrain). Harris Aerial Surveys will provide this service under the direction of Lynn Harris. The 1"= 400' coverage will be used for digital map compilation and will consist of thirty- eight East-West flight lines. Each photograph will be taken to overlap the preceding photograph in the direction of flight by approximately 60 percent. Photographs from adjacent flight lines will overlap by approximately 30 percent. The center of the first two and the last two photographs of each flight line will fall outside the mapping area. This will result in full stereoscopic coverage of the area. The photography will be suitable for attaining 1.0' contour interval mapping to national map accuracy standards. The 1'= 800' coverage will be used to produce the digital orthophotos and will consist of nineteen East-West flight lines. Each photograph will be centered on an existing facet (map sheet). This will ensure that each digital orthophoto will be taken from the center of the photograph, eliminating distortion and the need for mosaicking. All photography will be taken with Kodak Double -X 2405 Aerographic Film using a Wild RC -30 precision aerial mapping camera. The camera will be equipped with a standard six-inch focal length, forward motion compensation, and will have a current calibration certificate from the U.S. Geological Survey. Quality control procedures include carefully examining the film with respect to scale, overlap/sidelap, crab, tip/tilt and image quality. Exposures that do not meet standard specifications, or that are in some other way deemed unacceptable, will be re -flown as soon as conditions permit. All acceptable photography will be labeled with date, scale, flight line number and exposure number. Aerial Triangulation Prior to the photogrammetric map compilation, it will be necessary to expand the network of control points obtained in the field. This will be accomplished through an analytical aerotriangulation adjustment of the 1" = 400' photography. This will provide sufficient supplemental control for setting individual stereo -models in Contractor's photogrammetric plotting instruments. This portion of the project will be under the supervision of Stanley Niewiarowski, Certified Photogrammetrist #R912, of Dallas Aerial Surveys, Inc. In addition to providing supplemental control, the aerotriangulation process also serves to verify the field control values. Any errors in the surveyed control, which may otherwise go undetected, will be discovered and isolated during mathematical analysis. Dallas Aerial Surveys, Inc. will mark all the supplemental points (pug points) required for setting the stereo -models on film diapositives prepared from the black -and white aerial photography negatives. For this, Contractor will use a Wild PUG -4 point transfer stereoscopic instrument. The PUG -4 is equipped with a 60 -micron drill for "pugging/marking" the emulsion of the diapositives. The diapositives will then be set in a first -order analytical stereoplotter to measure relative (photo) coordinate values for each of the supplemental points and targeted ground control. These values, along with the known ground coordinates, will be used to compute the transformation and adjustment to ground coordinates values for the supplemental points. This will be accomplished with the J.F. Kenefick fully analytical adjustment program (RABATSBRATS). The industry standard for accuracy of aerial triangulation is 1/10,000 of the flight height or 0.24' on all ground coordinates. With the use of the RC -30 camera and the Zeiss first - order analytical P-1 stereoplotter, Dallas Aerial Surveys, Inc. will expect to get accuracy better than 1/13,000 of the flight height or 0.18'. Accuracy of., Tolerance RMS AV MAX Interior orientation 15 microns Relative orientation 10 microns Residuals o A. T. point 5 microns 0' 15 microns Residuals of Control Points 0.18' 0' 0.54' From the aerial triangulation results, a computer printout will be provided. A report will accompany the printout describing procedures and computer programs used. A listing of p. 12 any control not used in the final adjustment will also be shown. Descriptions of any disclosures encountered, and steps taken to rectify the discrepancy, will also be provided. The aerial triangulation report will contain the following: Narrative with brief explanation of the process Aerial triangulation index with all control points and photo centers Limited printout of final run of the bundle adjustment Floppy disk(s) with all aerial triangulation files Copy of camera calibration reports Pilot Project After the photography is accepted and digital map compilation begins, Dallas Aerial Surveys will deliver a pilot project of four maps to the City of Lubbock. These maps will be of the area indicated in Exhibit C as Maps 97, 98, 140 and 141. Deliverables from the pilot project will include all products outlined below, including DTM, digital orthophotography, contour and planimetric files, MicroStation, MGE and GeoMedia files, and hard copy products. At this time, all naming, file layering, topology, symbology, labeling, and format issues will be agreed upon, providing a foundation for the duration of the project. Once the pilot project is reviewed and accepted and all related issues settled to the satisfaction of the contractor and client, product delivery will proceed in batches of 16 maps every 30 days. Hard copy maps will be delivered 30 days after delivery of the digital files. Digital Map Compilation To produce the DTM and the digital planimetric vector data, Dallas Aerial Surveys, Inc. will place the diapositives in its first -order analytical stereoplotters. The stereoplotters will correct systematic errors due to earth curvature, light refraction and camera distortion. The encoders of the stereoplotters will be indexed to the ground coordinates of the supplemental points. This will allow us to digitize features from the photography into vector graphics based on the State Plane Coordinates System. Dallas Aerial Surveys, Inc. will be responsible for this portion of the project under the supervision of Kevin Kelly. Dallas Aerial Surveys, Inc. will utilize its Wild BC -1, Zeiss P-1 and Zeiss P-3 first -order analytical stereoplotters to compile digital planimetric mapping and digital terrain model to support 1.0' contours. With these stereoplotters, map data is compiled directly from the photography into digital form using Kork Digital Mapping Software. Features are collected in separate data layers and are defined by codes, which assign symbols, colors, pen sizes, and other attributes. After the data is compiled, it will be edited and formatted at a Pentium PC work stations also equipped with Kork Digital Mapping Software. During the Kork edit, Dallas Aerial Surveys, Inc. will process the vector data through a series of automatic editing software. During this process the system parameters are set so that the newly created vector data will snap together properly. A combination of the Kork Join, Nodes, and Clip programs are used to make sure that vectors are properly joined at end nodes and that polygons p. 13 close properly. This process will eliminate overshoots, undershoots and properly snap vectors together. The newly compiled vectors are separated into the following thematic layer schema within the Kork system and exported as MicroStation DGN files. The following categories will be collected: Roads & Streets, Curbed Perennial Drains and Shorelines Roads & Streets, Paved w/o Curb Intermittent Drains and Shorelines Roads & Streets, Unpaved Water Areas Track or Trail Dams, Earthen Bridges Dams, Masonry Culverts Index Contours Railroad Depression Contours Street Centerlines Approximate Contours Vegetation Spot Elevations Control (Control Stations, Benchmarks) Quality control procedures include making a set of test plots to verify that the above mentioned programs successfully manipulated the vectored features. Secondly, these same plots are checked against the aerial photos to ensure all features have been compiled. GeoMedia Conversion Applied Technological Services Inc., under the direction of Bruce Martin, will take receipt of the graphics data and verify that it has been topologically cleaned and placed in MicroStation DGN file format. The graphic elements will then be separated into individual DGN files that match the MGE category definitions currently used or defined by the City. Initially, all element graphics matching their associated feature definitions, per MGE category, will be written into a single DGN file, assuming the file sizes do not become too large to efficiently process. For example, if there are 8 MGE categories, then 8 DGN files will be created with the graphics that represent all the features in a single category. This will ensure that topology will be maintained for all area and linear graphics. The final DGN file coverage area format can be determined by the City of Lubbock and these large files will be cut up into the desired layout. The City's existing MGE project containing features, and any applicable associated attribute tables, will need to be acquired from the City. This information will then be used to featurize the MicroStation graphic elements. MGE tools will be used to feature tag the desired graphics to match the feature definitions present in the existing MGE project's feature table. If a feature has an associated attribute table, then a blank database record will be loaded for each feature processed. The MSLINK and MAPID columns will be populated in all tables. The final result of this process will generate MicroStation DGN files with all appropriate features and database linkages, if applicable. In addition, the associated database tables will be generated, delivered and available for use in the City's existing MGE project. p. 14 All digitized features will be both visual and coordinate edgematched with features from existing data. Attributes for adjoining features will also be identical. All graphic features that share a common boundary, regardless of digital map layer, will have the exact same digital representation of that feature in all common layers. No duplication of points that occur within a data string or occur as a single X and Y coordinate pair are permitted. Where graphic elements usually meet, they will also digitally meet. All area and polygon data will be exact mathematically. There will be no overshoots, undershoots, or offsets or pseudo nodes. Lines that connect polygons will intersect those polygons precisely. Every end point will be an intersection point of the respective polygon. A high quality cartographic appearance will be achieved. Transitions from straight line to curvilinear line segments will be smooth and without angular inflections at the point of intersection. The digital representation will not contain extraneous data at a non-visible level. There will be no jags, hooks, or zero length segments. The digital representation of linear elements will reflect the visual network structure of the data type. An element will not be broken or segmented unless that segmentation reflects a visual or attribute code characteristic, or unless the break is forced by database limitations. The structure of the map data will not inhibit the execution of GIS functions. Dallas Aerial Surveys, Inc. will process all coverages using MGE GIS commands as the last step prior to production of check plots and the delivery of data. The maximum tolerances for coverage processing are as follows: Fuzzy: 0.25 Dangle: 0.0 Grain: 1.0 Precision Double Dangling Nodes Not Acceptable Pseudo Nodes: Conditional Arc Direction: Per City of Lubbock Specification After processing, Applied Technological Services, Inc. will verify that features have not been omitted, snapped out of place, or trimmed as angles. All polygons and lines will be verified for proper closure and connectivity. Once a complete MGE project data set has been successfully compiled, it will be converted into a GeoMedia based project. If there are any differences in the desired format, design, or layout of the GeoMedia project as compared to the MGE project, the City will need to specify those differences prior to final delivery. Deliverables provided to the City from these processes will include an MGE project data set, which includes the DGN files, and a GeoMedia project data set. P. 15 Digital Terrain Model To orthorectify the raster image and to produce the one foot interval contours Dallas Aerial Surveys, Inc. will build a "Digital Terrain Model". This is accomplished with the diapositives set in the stereoplotters at the same time Contractor is collecting the vector data. Portions of the vector data will also be part of the DTM as breaklines. Dallas Aerial Surveys, Inc. will be responsible for this portion of the project under the supervision of Kevin Kelly. The DTM is collected with a series of breaklines and DTM points to define the vertical data. The elevations will be read along lines where the contours change direction or break. Drainage features would be defined as a hard break or abrupt change. Edge of pavement would be a soft break or slow change. The breaklines would be supplemented with DTM points, set on a 100' interval grid, to better express the terrain features. After the breaklines and DTM points are collected, they are processed through Terra Model software and the one -foot contours will be generated. The contours will be integrated back into Kork for plotting and editing. The DTM file will be delivered in a format to be specified at by the City of Lubbock on CD-ROM. After the editing and structuring of the data in Kork, a Plot file (1" = 200' horizontal scale) will be created for each facet and a set of ink-on-mylar map plots will be produced and delivered. Each facet will also include a standard title and border format containing specified information such as City of Lubbock logo, datum, contour interval, date of photography and map production, map scale, north arrow, accuracy note, map location diagram and Dallas Aerial Surveys' logo. Dallas Aerial Survey will provide a sample title and border format to the City of Lubbock for review and approval prior to creating any map sheets. Digital Orthophoto Each exposure of the 1" = 800' photography will be scanned using the Wehrli Rastermaster RM2 precision high-resolution photogrammetric scanner. The exposures will be scanned at 12 microns (2,117 DPI) to produce a ground resolution of 0.38' per pixel. Dallas Aerial Surveys, Inc. is responsible for this portion of the project supervised by Steven Fones. Running on Windows NT, the Vision Softplotter will overlay the raster image to the DTM. With the DTM, Dallas Aerial Surveys, Inc. will be able to remove image displacement due to terrain differences, and geo-reference the digital orthophoto to maintain spatial position. Photogrammetric equations derived from the control survey, camera calibration, orientation parameters and DTM are used in the processing. This will rectify the digital image to an orthographic projection by processing each image pixel by pixel. When the processing is complete, each digital orthophoto file will be resampled to a 0.5' ground resolution and written to CD-ROM in a format to be decided by the City of Lubbock and Dallas Aerial Survey. Each digital orthophoto file will match the City's existing tiling scheme. The digital orthophoto will be radiometrically and geometrically p. 16 corrected to enable adjacent files to be displayed simultaneously without obvious distinction between them. Orthophotos will not contain defects such as out -of -focus imagery, dust marks, scratches, or inconsistencies in tone and density between individual sheets. All mapping will meet or exceed National Map Accuracy Standards for photogrammetrically compiled data. For each digital orthophoto file, a reproducible hard copy mylar plot will be produced at the scale of 1" = 200'. Each plot will match the City's existing tiling scheme. Each sheet will also include the identical border format as the matching map sheet. The plots will be produced on the Cymbolic Sciences Lightjet 5000 large -format digital laser printer to photo quality and be suitable for reproduction on a Xerox system or through a Diazo process. Quality control procedures include merging the finished orthophotograph along with the vector data to verify that there is no mismatch. p. 17 i11 0 11 1 `r Resolution No. 2000-R Jan. 13, 2000 Item No. 34 Exhibit B Deliverables for Base Project (See Exhibit C for Project Area) Technical and quality control information Ground control and analytical aerotriangulation Ground control and analytical aerotriangulation for digital Comments One copy of the flight plan and control layout for each orthophoto flight Camera specifications and current (within 3 years) USGS camera calibration reports for all equipment used on each orthophoto flight One copy of FGDC compliant metadata for all digital files in Word97 format in a format and containing information to be agreed upon by Client and Contractors Ground control and analytical aerotriangulation Ground control and analytical aerotriangulation for digital orthophotography and contour mapping One copy of the ground control and aerotriangulation report for each orthophoto flight Documentation for each benchmark or ground control point, including copies of field sketches Permanent monumentation of eight (8) to twelve(12) 2ndorder accuracy control points Aerial Photography Contact prints Aerial photography capable of generating 6" pixel resolution digital orthophotography and 1 foot contours One copy of photo diapositives for each orthophoto flight Digital Orthophotography Creation of digital orthophotos at 6" pixel resolution for digital orthophotography One copy of the digital orthophoto files in uncompressed format One copy of the digital orthophoto files in MrSid format p. 18 1:200 scale 4 mil mylars of ortho photos Digital Terrain Model Digital terrain model creation NAD83 and NAVD88 Digital terrain model creation NAD27 and NAVD29 One copy of the DTM in MicroStation format Contour Mapping and Planimetric Data Collection Contour mapping at 1 foot intervals NAD83 and NAVD88 Collection of Planimetric data in Appendix C One copy of the 3D planimetric vector file in MicroStation format 1:200 scale 4 mil. mylars of contours Training Five days of on-site training in facilities provided by the City of Lubbock P. 19 Exhibit C Index of Orthophotography Map of Project Area p. 20 Hartland Ave. Zeeland Ave. Quitsna Ave. Inler Ave. Alcove Ave. Upland Ave. Milwaukee Ave. Frankford Ave. Slide Rd.
