getnodeind

Gets indices of nodes that are closest to given locations

Functions for reading, analysing and plotting river networks.
For this package, river networks consist of sections and nodes with associated attributes,
e.g. to characterise their morphological, chemical and biological state.
The package provides functions to read this data from text files, to analyse the network
structure and network paths and regions consisting of sections and nodes that fulfill
prescribed criteria, and to plot the river network and associated properties.
