How were features blocked from routing?
The LENGTH value for any feature with SAVENEG set to 1 was multiplied by – 1. By default ROUTE would not traverse along any feature with a negative length. Afterward, the reach file topology was re-built to revert negative lengths back to positive. • How can I see the results of routing the stream network? Go into ARCPLOT or ARCEDIT and colorshade the arcs based on their CEN values. Only features with CEN values greater than 0 had been routed. • What is the purpose of the item PNTR#? PNTR# was added to the AAT file and calculated equal to the internal record numbers. (coverage#) This was done just prior to using ROUTE on the stream network. The reason for adding PNTR# was to preserve the order of the Arc Attribute Table into an item at that particular time in the development of the reach files. Centerlines • What was the purpose of inserting centerlines through water bodies and wide rivers? Centerlines were added o provide single-line transport paths thru water body features. All but j
