Using RivEX+ to sample a river network

This sampling tool is only available to you if you have purchased RivEX+

• RivEX+ is capable of generating points upon a river network using a variety of sampling techniques. The output is written to the default directory C:\RivEX\Output as a Shapefile.

• Some of these techniques require your network to have been pre-processed by RivEX.  To find out how RivEX+ generates a random point on the network, click here.

• The current tool can sample the your network using the following techniques:

• Sampling every polyline in the network
• Stepping along the network using a user defined distance
• Random points (a set number or as a % of the network)
• Stratified sampling using a grid (samples a set number within each grid cell)
• Stratified sampling using a user supplied polygon layer
