sequenceverts {riverdist}

Store Vertices in Ascending Sequence

Description

Rearranges the vertices of a river network object so that vertices are stored sequentially moving up river for all segments (coordinates [1,] are the bottom of each segment).

Usage

sequenceverts(rivers)

Arguments

rivers

The river network object to use

Value

A new river network object (see rivernetwork)

Note

Even without calling sequenceverts, the vertices will be stored sequentially - either moving up river or down for a given segment. What sequenceverts() adds is a standardized direction.

Currently, no function in package 'riverdist' requires the vertices to be stored sequentially.
