Initially drawn in ArcMap by digitizing over orthoSegments were divided based on 1 mile incrementsAddress 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
