eGeo-Spatial Data Creation Conversion and Integration Without digital data any GIS system is useless . Various Departments within Public Works expressed the need to acquire and integrate geo-spatial data . Coastal Engineering If is recommended that the Coastal Engineering Section utilize GPS to gather information related to the Habitat Conservation Plan for sea turtles . Currently , every sea turtle crawl , an average of 6,000 per summer, has been collected using GPS , but the data is not stored in an ESRI GIS format . GTG recommends a high quality Trimble sub meter GPS unit be used for all future data collection activities . The data should then be loaded into an ESRI GIS database format so that if can be analyzed within GIS software . The Coastal Engineering Section should work with the recommended GIS Specialist of the Engineering Division to perform these tasks. Additionally , aerial photography of the beaches will continue to play an integral role in the successful implementation of Coastal Engineering GIS activities . The Section currently maintains color aerial photography and bi-yearly updates are planned . The Coastal Engineering Section currently does not have a database for storing sea turtle nesting locations or crawl data . As aforementioned , GPS units can be used to acquire geo- _ spatial data such as sea walls and nesting sites and subsequently integrated into the Department ' s Intranet Data Browser. This data , along with other base map information such as streets , parcels , aerial photography of the beaches , and county boundaries , will allow Coastal Engineering staff the benefit of viewing digitally via an online map , current sea turtle activities for analysis and planning purposes . Other important features to be collected , as noted by Coastal Engineering staff, include the following : • Armoring • GPS Fill Templates • Sea -walls Storm Water At present, the Storm Water Division does not maintain any GIS data . There was a stated need to be able to view and map specific GIS data layers related to storm water, including : • Storm water Infrastructure (catch basins , drop inlet locations with attributes ) • Basins • Water Qualify • 100 Drainage Outfalls with attributes ( cross-sections, condition of banks, erosion , pipeline diameter, condition of pipe, type of material , and more) These layers represent a significant investment for the County, and the Storm Water Division has identified the need to acquire this data and ensure that these layers are comprehensive and up-to-date . A general recommendation is made for the completion of this geo-spatial data creation within the first two years of implementation . Before any data conversion or collection begins , agreed -upon utility data models ( as discussed in the Storm Water Division Specific GIS Needs section later in this needs assessment) must be created . It should also be noted that GIS data creation and conversion may be affected by the coordinate system transformation required for most of the geo-spatial data that will be implemented in the Utilities Services Department ( see the Utilities Services Department Needs Assessment in this chapter for additional information ) . 70 GIS Needs Assessment and Implementation Plan Chapter 1 - Departmental GIS Needs Assessment
