<br /> Section 5: Proposed Scope & Techniques 16 <br /> 4) Quality Control <br /> Communication <br /> Our quality control (QC) and quality assurance (QA) procedures are thorough and extensive starting with <br /> strong communication with the City GIS Coordinator and technical staff. Specifically, we propose to have <br /> montWy meetings that will include: I) written status report, 2) current project schedule, 3) level of effort <br /> and cost breakdown. Periodically we will include sample products (digital and hardcopy) that demonstrate <br /> progress and challenges that may arise. We also propose to meet with technical staff on as-needed basis but <br /> at least monthly. The objective of these meetings is to apprise City staff of any technical issues that may <br /> arise, and use their expertise in resolving solutions. We will be providing check plots and preliminary <br /> digital data constantly and therefore, will use this forum to discuss potentially systemic problems and <br /> solutions, and provide feedback on specific issues. <br /> Documentation <br /> The project will begin with a Specifications Document that details: 1) cartographic conventions (e.g. <br /> symbology, layer naming conventions, linetypes, annotation characteristics), 2) feature attributes, and 3) <br /> preliminary database design criteria will be submitted at the very beginning of the project. This document <br /> will form the foundation the project and needs discussion and approval in draft form at initial technical <br /> meetings. It is however, a 'living' document and therefore, will change over the course of the project. Each <br /> change will be highlighted in status reports at technical meetings. <br /> Technical Approach <br /> General <br /> We have constructed a suite of in-house utilities that standardize the data entry. For example, we have a <br /> standard template that defines the domains of both physical and descriptive attribute characteristics. We <br /> have also created custom routines that will help reduce cost and the likelihood of typographical errors. <br /> We use 100% checking for our quality control, and generally do not employ statistical methods because of <br /> the broad-based assumptions that are required. <br /> Topological Testing <br /> Coordinate errors are tested using two independent methods: once in AutoCAD Map, and again in Arclnfo. <br /> AutoCAD Map has excellent automatic coordinate evaluation and cleanup routines, but in our experience, <br /> often overlooks many errors. ArcInfo does not have the elegance of AutoCAD, but is virtually faultless. <br /> All network topologies will have a direction arrow generated for each segment. This will test that segments <br /> are digitized in the proper direction. Topologies will be tested dangles. It is our policy not to accept any <br /> coordinate errors even if they do not represent a topology error. For example, an overshoot, or duplicate arc <br /> will not generate a topology error but will not pass our quality control. Moreover, our standard is to set our <br /> fuzzy and dangle length tolerances to 0.9 feet, less than the smallest feature, and large enough to inspect for <br /> errant junctions in a coverage's geometry. <br /> Check plots. visual inspection and lOO% checks <br /> Separate staffing is employed for visual inspection of the data. We prepare check plots of all data <br /> superimposed over the scanned source documents as shown in the sample map, followed by visual <br /> inspection of all plotted elements. Each map feature will have a highlighted mark in a specific color <br /> placed through the feature while it is compared with the source document. Our standard checklist is <br /> provided to the QC staff so that all features pass a prescribed set of tests. These check plots are returned to <br /> the technical operators for correction who, in turn, highlight the corrections as they are completed in a <br /> different (standard) color. These markups will be submitted to the City along with new checkplots for <br /> review and acceptance. <br /> Lynx Technologies City of Redwood City Street Lighting GIS Project <br />
