Cross-section analysis is primarily used for detailed analysis of linear features in geospatial data, such as roads, rivers, pipes, and so on. The function allows users to set cross-section lines on specified linear features and obtain information about the intersections of these cross-section lines with linear features, including coordinates and object IDs. By analyzing this intersection information, you can obtain the geometry, size, slope, and other related attributes of the cross section to gain insight into the characteristics of linear features at specific locations. Cross-section analysis is widely used in many fields, such as traffic planning, hydraulic engineering, pipeline system design and so on. The current function supports use in spherical scenes.
Function entrance: on the "Three-dimensional Spatial Analysis" tab-"Cross-section Analysis" item;
Operating steps
- Data preparation: 3D line data set is used for section analysis; in order to avoid the pipeline display effect is not obvious, thematic drawings or lofting can be made according to 3D line data set, processed into 3D model data, and then further processed into 3D model tiles (note that instantiation is not checked during processing), which are used for loading and displaying in UE.
- Select the data source and data set: After loading the model tile, the pipeline effect will be displayed in the scene, and then select the data set and the corresponding line data set.
- After the data set is set, click Analyze, pick two points in the scene to form a cross section, and then get the cross section analysis information. Click Pipeline to get the corresponding object attributes and display them in the result information.
- The plug-in is only an example reference for the display of cross-section analysis information. Users can draw more detailed and business-compliant effects at the front end according to the acquired attribute information, such as geometric shape and size.
