Va!leyCom Statement of Work 5.3 Geofile Maintenance Layers The following provides a description of the Layers that GDR will maintain. 5.3.1 STREETS (WITH ROUTING. IF APPLICABLE) Maximum Limit Updates of the total number of segments in the original base map in the following quantities may be performed in a Release before the Maximum Limit is exceeded, as follows: • Up to 5% for Releases on a quarterly Maintenance Cycle • Up to 10% for Releases on a bi-annual Maintenance Cycle • Up to 15% for Releases on an annual Maintenance Cycle Spatial 1. Any new segment additions will be digitized and/or corrected to the most recent aerial Accuracy imagery that GDR can obtain. If roads are so new that they do not appear on any ~, imagery, GDR will then add segmentation using reasonable commercial efforts with the understanding that the Layer will be corrected to spatially accurate imagery in a I subsequent Release when said imagery becomes available to GDR. 2. Any original segmentation found later to be in error in the original base map, will be corrected without counting against the Maximum Limit. 3. GDR will not ortho-rectify an entire street fife to a completely different source data set as part of a maintenance update. An example of this might be if a Licensee receives an j engineer grade (1 inch accuracy) line file that they wish to transfer existing attributes to This is not part of the maintenance cycle, but could be done as a different work order at an additional cost. Attribution 1. A 'golden" address range or point fife (such as CAD, SITUS, or MSAG data) may be specified by Licensee during the initial file build. This file or files is/are used to validate the deliverable street file and ensure all address and name data is contained within. Customer may provide GDR with an updated version of their `golden" file for use in maintenance updates; however GDR will not accept additional "golden" files or a golden file that comes from a differing source with respect to the original. ~I 2. If a "golden" file was not provided to GDR by Licensee as part of the original Specifications. none may be provided for subsequent Release unless mutually agreed in writing between GDR and Licensee. Alternatively, a "golden" file may be incorporated into future Specifications at an additional cost. 3. The unique ID field will be maintained during a maintenance update. At Licensee's request. deleted segments may be provided in a separate file. New segments will be ', given new ID numbers, and one part of any split segments will retain the original ID. while the other split portions will receive new IDs. ', 4. All node, cross street. and polygon (ciry_ police, fire, EMS, etc.) attribute data will be updated for each record if appropriate. ', Integration Scope 1. GDR will receive the countywide street centerline file from Santa Ana. '~ 2. GDR will change the format of the countywide streets to match Santa Ana streets (field names. field order, field values, missing fields). 3. GDR will integrate the countywide and Santa Ana datasets - Remove countywide streets that exist in Santa Ana street centerline layer. - Edge-match the Santa Ana streets to the countywide streets. - Ensure topological/attribute consistency such that routability across dataset borders are maintained. - Apply left/right Santa Ana FRDs values to countywide streets, if these values do _,_ not exist in the countywide dataset. 8 Digital Dnve.
