  • Can a marker system and map book be createdto distinguish points along the river forsearch and rescue?
  • Yes!
  • Create a river centerline that can be used to markpoints along the Saluda, Broad and Congaree rivers.
  • Create a database of points that works with the rivercenterline.
  • Create a map grid system that is useful to multipleagencies.
  • Produce a map book that can be used by firstresponders along with search and rescue teams.
  • Create a database of features along the river such as:Boat landingsAccess pointsBridgesPower linesRapidsLanding ZonesCell/Radio TowersOther landmarks
  • Load the River Centerline, Address Points, Map Bookgrid, and all features into Pictometry Online!
  • Where is the “centerline” of the rivers?Where is the official beginning point?
  • Navigating through/around islandsA comprehensive numbering scheme forall rivers.
  • Consideration of State and Federal acceptanceStandard for statewide use of waterway centerlinesInterdepartmental and interagency relationships
  • Creating a centerline that is both accurate andacceptable for statewide coverage
  • Interagency communication about standards forcenterline and markersStateline locationObtaining LiDARbased centerlineAccuracy of LiDARcenterline
  • Consideration of who will be using this data!Sheriffs Department/Marine Patrol, FireDepartment, EMS , 911 Dispatch, The General PublicMe!
  • Initially drawn in ArcMap by digitizing over orthoSegments were divided based on 1 mile incrementsAddress range was added to each segment
  • What increments need to be used (.10 mile)?• Numbering displayed in map book• Numbering displayed in CAD• Numbering displayed on marker signs (what fits the sign)
  •  Markers are based on mileage Address Points coincide with the mileage but arebased on the range on the riverC10.5 = 1050 Congaree RiverMarker Address
  •  Acquisition of centerline based on LiDAR from DNR Confirmation of SC/NC state line affected wheresegments and points were located on the rivers Calculation of the points based on new centerlineand range
  • The map grid system
  • USC Geography 495 Fall 2012
  • CAD PictometryMap book Wall map
  • Loading into multiple CAD systemsPosting the river marker signsAddressing feature along the river banksFunding for river markersFunding for map book printing
  • *Any significant features along the rivers that need to be identified, please let us know.*
