o' CT,; &GO Countywide Pavement Management Plan Guidelines <br />Local Tax Dollars at Work <br />XIII. Appendix C — GIS Digital Data <br />Introduction <br />The OCTA GIS Section maintains a spatial inventory of transportation infrastructure which mostly <br />consists of major arterial streets, roads, and highways. A key component of road information is <br />pavement condition. Maintaining an inventory of pavement condition will enhance OCTA's GIS <br />visualization and analysis capabilities and assist in understanding the transportation investment needs <br />throughout the region. Therefore, a GIS dataset in digital format should be included in this report. <br />If the agency is unable to provide pavement data in the requested GIS format, a request for exception <br />must be submitted by the agency. When requesting an exception, the agency must provide a letter <br />signed by the Public Works Director with an explanation and a timeline of when the agency will have <br />capabilities of providing pavement data in the required GIS digital format. <br />Structure of GIS Data <br />The GIS dataset must consist of linear geographic features that represent road/street segments. All <br />segments that are part of the report should be included in the GIS dataset. The attribute information <br />of each segment should generally follow the format of the Complete Listing of Current Street <br />Conditions in Appendix B above. <br />The GIS data requirements are discussed below. Most commercial and open -source GIS software <br />provide industry -standard tools to manage GIS data to meet these requirements. <br />GIS Dieital Data Format <br />The GIS data must be submitted in either one of the following formats: <br />• Esri Shapefile, or <br />• Esri File Geodatabase <br />Matariata <br />The GIS data are required to have associated metadata. The minimum metadata items required are: <br />• Title of Dataset <br />• Tags (A set of words that can be used by GIS to search for the resource. For example: <br />"pavement", "transportation", "roads") <br />• Summary (A brief purpose statement of the dataset) <br />• Description (A brief narrative of the dataset's content) <br />• Credits (A recognition of those who created or contributed to the resource) <br />Effective March 2024 A-15 <br />
