He wants to create an adjacency or connectivity matrix between major nodes along the interstates, across the entire network. His goal is to assign to the major nodes the total number of connections or possible routes between them, and the sum of the vehicle capacity of all those connections.</SPAN><BR /><BR /><SPAN>I've looked at Network Analyst and the schematics tools. I haven't worked with either before and the they don't specifically seem to do anything like this but can't be sure. Any ideas on tools or workflows to follow for this?</SPAN><BR /><BR /><SPAN>Thanks,</SPAN><BR /><SPAN>David</SPAN></BODY></HTML> Fri, 22 Jun 2012 15:19:44 GMT https://community.esri.com/t5/geoprocessing-questions/connectivity-or-adjacency-matrix-in-arcgis/m-p/336751#M11801 DavidMedeiros 2012-06-22T15:19:44Z Re: Connectivity or adjacency matrix in ArcGIS? https://community.esri.com/t5/geoprocessing-questions/connectivity-or-adjacency-matrix-in-arcgis/m-p/336752#M11802 <HTML><HEAD></HEAD><BODY><BLOCKQUOTE class="jive-quote">His goal is to assign to the major nodes the total number of connections or possible routes between them, and the sum of the vehicle capacity of all those connections.<BR /></BLOCKQUOTE><BR /><BR /><SPAN>Can you be more precise on what you want in the matrix?</SPAN><BR /><BR /><SPAN>That is, for a list of (major) node locations, make a matrix of each node to every other such node with some value.
