Redes 0.1.0

by Grupo gvSIG last modified 2010-10-29 15:33

This tool is used to check the connection status of network nodes from a given point.

To use this utility first load a line layer with a network topology. If the network topology has already been created for the layer then select Network|Load topology from previously generated network from the menu. If no topology exists then select Network|Generate network topology.

To access the connectivity tool select Connectivity from the Network menu.

Use the Set source flag wizard to enter the coordinates of the Origin point on the network. If required, choose an associated layer from the drop-down list. Finally, in the options section choose the network direction, either normal or inverse. It is also possible to specify maximum distance and cost values in order to restrict the extent of the connectivity calculation.

Click Calculate to generate a connectivity analysis and to display the results in the View (Note that at this stage symbols denoting stops will no longer be visible in the View, only the origin point of the connectivity analysis will be displayed).
