City of Santa Ana, CA Page 14 2024 Citywide Pavement Management Plan — OCTA Submittal Final Report — May 27, 2024 XIII. APPENDIX C —GIS DIGITAL DATA Introduction The OCTA GIS Section maintains a spatial inventory of transportation infrastructure which mostly consists of major arterial streets, roads, and highways. A key component of road information is pavement condition. Maintaining an inventory of pavement condition will enhance OCTA's GIS visualization and analysis capabilities and assist in understanding the transportation investment needs throughout the region. Therefore, a GIS dataset in digital format should be included in this report. Structure of GIS Data The GIS dataset must consist of linear geographic features that represent road/street segments. All segments that are part of the report should be included in the GIS dataset. The attribute information of each segment should generally follow the format of the Complete Listing of Current Street Conditions in Appendix B above. The GIS data requirements are discussed below. Most commercial and open -source GIS software provide industry - standard tools to manage GIS data to meet these requirements. GIS Dieital Data Format The GIS data must be submitted in either one of the following formats • Esri Shapefile, or • Esri File Geodatabase Metadata The GIS data are required to have associated metadata. The minimum metadata items required are: • Title of Dataset • Tags (A set of words that can be used by GIS to search for the resource. For example: "pavement", "transportation", "roads") • Summary (A brief purpose statement of the dataset) • Description (A brief narrative of the dataset's content) • Credits (A recognition of those who created or contributed to the resource) Spatial Geometry Type The spatial geometry of the segment features must be lines that represent the roadway centerline as accurately as possible. Protection The GIS data must have spatial reference information and have its coordinate system identified and embedded in or associated with the data file(s). All GIS data submitted to OCTA should be in the following projected coordinate system: • NAD 1983 State Plane California VI FIPS O406 (US Feet) - More information about this system can be found at: https://spatialreference.org/ref/epsg/nad83-california-zone-6-ftus/ :, A
