Please add a new solver to the network analyst representing functionalities of the ArcInfo Workstation NODEDISTANCE command, i.e. the option to generate o/d-matrices based upon airline or Manhattan-distances. It would be great if this solver would allow to calculate network distances (i.e. shortest paths over a network dataset), airline distances and Manhattan distances simultanously, and would store all three results in one matrix. This would enable us to directly compare results of the three procedures easily.
