Scarc three rivers run through it 20130211

  1. 1. Can a marker system and map book be createdto distinguish points along the river forsearch and rescue?
  2. 2. Yes!
  3. 3. Create a river centerline that can be used to markpoints along the Saluda, Broad and Congaree rivers.
  4. 4. Create a database of points that works with the rivercenterline.
  5. 5. Create a map grid system that is useful to multipleagencies.
  6. 6. Produce a map book that can be used by firstresponders along with search and rescue teams.
  7. 7. 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
  8. 8. Load the River Centerline, Address Points, Map Bookgrid, and all features into Pictometry Online!
  9. 9. Where is the “centerline” of the rivers?Where is the official beginning point?
  10. 10. Navigating through/around islandsA comprehensive numbering scheme forall rivers.
  11. 11. Consideration of State and Federal acceptanceStandard for statewide use of waterway centerlinesInterdepartmental and interagency relationships
  12. 12. Creating a centerline that is both accurate andacceptable for statewide coverage
  13. 13. Interagency communication about standards forcenterline and markersStateline locationObtaining LiDARbased centerlineAccuracy of LiDARcenterline
  14. 14. Consideration of who will be using this data!Sheriffs Department/Marine Patrol, FireDepartment, EMS , 911 Dispatch, The General PublicMe!
  15. 15. Initially drawn in ArcMap by digitizing over orthoSegments were divided based on 1 mile incrementsAddress range was added to each segment
  16. 16. 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)
  17. 17.  Markers are based on mileage Address Points coincide with the mileage but arebased on the range on the riverC10.5 = 1050 Congaree RiverMarker Address
  18. 18.  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
  19. 19. The map grid system
  20. 20. USC Geography 495 Fall 2012
  21. 21. CAD PictometryMap book Wall map
  22. 22. Loading into multiple CAD systemsPosting the river marker signsAddressing feature along the river banksFunding for river markersFunding for map book printing
  23. 23. *Any significant features along the rivers that need to be identified, please let us know.*
