4Dmap 1...........-.................. .' .... . . ,. ~ - . . ''1.''''' _......,_' c'" Standard Deliverable Transmap will host the images over the internet. This allows for multiple users to view and use the data from a central location. This ArcGIS Server allows users to view images in a web based environment. A map book of driven roads is also included as a deliverable. Standard Deliverable Transmap will deliver all images on an external hard drive. Quality Control and Data Acceptance Transmap will QC images obtained by the mapping vehicle to ensure they are satisfactory to meet the objective of the right of way asset inventory project. The focus of this project is sign inventory. To ensure the highest quality images, image capture activities will not be performed during low-light or adverse weather conditions. In-field image quality control will be performed for the purpose of identifying any unacceptable images. Unacceptable images will be re-collected. The specified route network will be compared against that of which has been imaged to ensure no route segments have been overlooked. Missing route segments will be re-driven and imaged. Route segments may not be imaged when they are not accessible due to construction; temporary or permanent closures; or they may not exist as indicated in the supplied base data-sets (i.e. - paper streets). Positional accuracy will be maintained and verified through the use of QC points established within the road network. Reference coordinates will be established for said QC points. QC point locations will be derived from the collected images, with discrepancies between the known reference coordinates and the measured coordinates (from the images) noted. 90- percent of the derived horizontal coordinates within 35-feet from the imaging van will fall within 1 meter of the known reference coordinates. If 10-percent or more of the selected control points do not meet the accepted accuracy criteria, corrective actions will be taken. Linear Referencing System Creation The centerline is the foundation for all asset extraction. The centerline will be reviewed to produce a linear referencing system. All assets will be tied to the centerline and the LRS by route name and milepost positions. Transmap has not included pricing to fix or add data to the centerline file. ~ Transmap has reviewed the basemap . Total miles within City Limits: 164 Centerline Miles ~ After Transmap has reviewed the centerline file the City of Redwood City may need to clarify data like; naming issues.
