Aim:
To create a Service Map through the use of
Network Analyst toolset
Procedure:
Step 1: Map Input
A Base map or toposheet on which Roads and Facilities Point
features are digitized and exported as shapefiles.
Step 2: Map
Processing
·
Geo-reference the base map with known location
coordinates.
·
Import the digitized Line and Point shapefiles
into the target Geo-database.
·
All Line entities of road feature class, needs
to be split into right-angles at junctions. Hence use the Planarize line tool
from Topology tool options under Editing mode.
·
In ArcCatalog, create a Network Dataset and add
Road features.
·
Enable the Network Analyst option in Extension
and choose the Service Area analysis.

·
On properties of Service Area, Set the Impedance
to Break Values of Length in Meters.
·
Solve for Service Area. The Service Area (In
custom Break Values) will be generated for Facilities Point Location.
Step 3: Map Display
The final Output map
can be displayed with Map Elements and grid properties of Layout.
Conclusion:
A Service Area Map through the use of Network Analyst
toolset is created.
