This tool calculates the service area for each stop according to user-specified costs.
To start using this utility load a line layer with a network topology. If a network topology has already been created for this layer then select the Service Area option from the Network menu. If the topology doesn't exist yet then create one by selecting "Network|Generate network topology.
In the View load a point layer containing stops or insert a series of stops using the tools from the Network toolbar.
To access the Service Area tool, select Network|Service Area from the menu.
This opens the following form where stops can be also uploaded by clicking the Load stops button.
Once the stops have been loaded enter a cost for each one in the Costs column.
Click the Calculate Service Areas button to calculate the areas.
