RivEX can extract and store various statistics for each node.  Progress can be tracked in the progress window and status bar.


The tool uses Strahler order, so this field need to be pre-generated.


The results are stored in a dBase file called called LayerName_Node_statistics.dbf.  For example if you processed a river network call riv,  RivEX will create a file called riv_Node_statistics.dbf.  If this file exists already you will be asked to overwrite it.  This dBase file is stored in the Output sub folder in RivEX_Workspace for the network.


The statistics calculated for each node are:
