3D Optimal Path Analysis

Instructions for use

3D Optimal Path Analysis is used to find the path of least resistance between two points in a specified 3D Network. If 3D Optimal Path Analysis is performed on multiple nodes, the nodes must be accessed in the order in which they are selected. It should be noted that the minimum resistance has many meanings, such as the shortest time, the lowest cost, the best road condition and the least toll stations based on the consideration of a single factor, or the best road condition and the least toll stations based on the comprehensive consideration of multiple factors. Here, 3D Optimal Path Analysis is to analyze the path with the least cost through a series of sites in a specified order.

Function entrance

  • Traffic Analysis tab-> Road Network Analysis group-> 3D Optimal Path Analysis button

Operation steps

  1. Load the 3D Network data in the scene for analysis and adjust the data to a reasonable angle.
  2. Click Traffic Analysis tab-> Road Network Analysis group-> 3D Optimal Path The Analysis button pops up the Instance Management and Environment Settings panels.
  3. In the Network AnalysisEnvironment Settings window, set the Analysis Parameters, such as weight field, node/Edge ID Field, etc.
  4. In the Instance Management window, you can perform the Parameter Settings of 3D Optimal Path Analysis.
  5. Stop Management: supports operations such as adding, removing, and exporting sites on the current 3D Network data layer.
    • Add by Mouse : Click Add by in the toolbar inside the Instance Management panel Mouse button, or click the Add by Mouse " item in the Context Menu of the Site , and then move the mouse to Scene. Click the left mouse button to Add site. Stop Info will be displayed in the site directory in real time. Click the right mouse button to end the addition.
    • Import Stops: select the "Import" item in the "Site" Context Menu to pop up the Import Stops dialog box to import existing sites to participate in the analysis.
    • Remove Site: select the Remove item in the Site Context Menu to remove all subsites in the site. If the Remove item in the Context Menu of its child node is selected, only this child item will be removed.
    • Export site: select the Export item in the Site Context Menu to export and save all sites in the analysis instance as Point Dataset. If the Export item in the Context Menu of its child node is selected, only this child item will be exported.
    • Specific Stop Management: The Context Menu of a specific site provides operators such as Move Up, Move to Start, Move Down, Move to End, and Rename. The order and position of specific sites in the list can be changed by moving up and down. The Move to Start and Move to End actions set a site as the starting or ending point of the analysis. The rename operation can change the name of a specific site.
      Hint:
      When 3D Optimal Path Analysis is

      performed, the analysis is performed in the order of the sites in the site list. Therefore, if necessary, you can change the order of the stations by moving up, moving down, Move to Start, Move to End, and so on.

  6. Barrier point management : The Instance Management panel provides management operations such as adding, removing, and exporting barrier points. The method of operation is similar to Stop Management.
  7. When the Parameter Settings are complete, click the Execute button in the toolbar to execute the 3D Optimal Path Analysis.
  8. After the execution completed, a Result Route is generated under the Analyst Result directory tree. Click The Save as Dataset item in the Analyst Result Context Menu or select the Save as Result Dataset item in the Result RouteContext Menu to export the result path as 3D Line Dataset. And save to that specified Datasource.
