Solving Network Problems with Latest SuperGIS Desktop Extension
An Introduction to SuperGIS Network Analyst
Network analysis has been widely applied to various fields. Besides the shortest path, network analysis can also solve various problems, including closest facilities, service area, vehicle routing problem and location analysis, etc.
Solving Network Problems with SuperGIS Network Analyst
Superb Network Analyst 10
SuperGIS Network Analyst 10 inherits all the practical functions from the Network Analyst 3 such as the shortest path, the superior route, etc. In this latest version, Supergeo team adds a new capability: the O-D Matrix and also augments some adjustable settings in the existing Extension. The O-D Matrix is aimed to help users calculate the least cost between origins and destinations. In the real case, O-D Matrix can assist users to conduct long-term transportation planning or short-term transportation improvement. The O-D Matrix in SuperGIS Desktop allows users to set origin and destination layers. With the O-D Matrix, you will obtain a table which records the travel cost between each origin and each destination.
The O-D Matrix of SuperGIS Network Analyst 10
Utilize O-D Matrix
When a city government wants to improve the public transportation within a certain community, the planner should examine the distance from each household to every bus station in the district. By using SuperGIS Network Analyst, what the planner needs is only preparing the position of houses, bus stations, and the road network. Then, he or she can utilize the O-D Matrix to get the result. The detailed steps are listed below:
- Create a network dataset
- Open Network Analyst toolbar, click Network Analyst and select the O-D Matrix.
- Select Stops in Network Location Window.
- Import the original data and destination data as the network location.
- Set up other settings, such as barrier, and analysis parameters.
- Click Solve to get the result.
After these steps, the planner can get the distance between houses and bus stations. According to the result, he or she can decide how to improve the accessibility of public transportation in a certain community.
Calculating Multiple Routes with Network Analyst
What’s More in the Network Analyst?
SuperGIS Network Analyst 10 also enhances the capability of Superior Route Analysis and adds other flexible settings for getting better results. Superior Route Analysis assists users to find an optimal route from the origin stop and visiting stops to the end stop in a network system. The analyst is usually applied to searching the optimal solution for Traveling Salesman Problem. The latest Superior Route Analysis allows users to reorganize the stops, and they can choose to analyze the best route based on the determined order, or reorder all visited points but preserve the first stop, or rearrange and Keep First/Last stop, etc. There are also other newly-added settings such as the settings for snapping, and more options for importing network locations to meet different analysis needs.
A More Flexible Setting for Superior Route Analysis
A Quick Summary
This featured article introduced what’s new in SuperGIS Network Analyst 10, including how to utilize O-D matrix to get the cost information between origins and destinations. Furthermore, with the newly-added functions and flexible options in SuperGIS Network Analyst 10, users will run network analyses more smoothly and solve issues with spatial insights.
