Basic network properties
•RivEX can analyse the basic properties of a river network and send the results directly to MS Excel. Progress can be tracked in the progress window and status bar.
•The whole network is included in this analysis, the output does not differentiate between catchments.
•The basic properties of the network extracted are:
oNumber of polylines in the network
oTotal number of vertices in the network
oMinimum polyline length
oMaximum polyline length
oSum polyline length
oMean polyline length
oNumber of Nodes
oNumber of Mouths
oNumber of Sources
oNumber of Pseudo nodes
oNumber of nodes with valency X*
oNumber of interior links
oNumber of exterior links
oNumber of outlet links
* = This row will expand to however many required depending upon the largest valency.
Interrupting the data transfer by clicking on the Excel window will cause the transfer to fail! Excel will always minimise when transfer is complete, so be patient if you are processing a large river network.
