Function Description

Edgematching refers to the connection of the edge line objects of adjacent map sheets. When the map is spliced into a map after the map is compiled and mapped separately, there is usually a problem that the edge objects of the map sheets are not connected. This function can be used to connect the line objects.

This function is applicable to Line Dataset. There are three Edge matching modes: Other Edge, Middle Point, and Intersection.

Parameter Description

• Source Data: Set the Source Dataset and its Datasource. The coordinate system of the Source Dataset must be consistent with the coordinate system of the Target Dataset.
• Target Dataset: Set the Target Dataset and its Datasource. It should be noted that Edgematching will directly modify the Target Dataset. It is recommended to back up the Target Dataset before this operation.
• Parameter Settings：
  • Edge Connection Mode: It is used to set the edge connection mode. Application provides three edge connection modes, and the specific description is as follows:
    • Other Edge: The edge connection point is the endpoint of the edge association record in the Target Dataset, and the edge endpoint in the Source Dataset will be moved to this connection point.
    • Middle Point: The junction point is the midpoint of the junction endpoints of the Target Dataset and the Source Dataset, to which the junction endpoints in the Source Dataset and the Target Dataset will be moved.
    • Intersection: The junction point is the intersection point of the junction line and the junction line of the junction endpoints in the Target Dataset and the Source Dataset, to which the junction endpoints in the Source Dataset and the Target Dataset will be moved.
  • Edge Connection Tolerance: It is used to set the tolerance value of the edge connection of the line between the source data and the Target Dataset. If the distance between the adjacent endpoints of the line object is within this tolerance range, the two lines are considered to be connected. The tolerance defaults to 1, and the unit remains the same as the Source Dataset's Unit.
  • Attribute Reservation: Support the setting of reserving the attribute values of participating Edge Match Union objects. You can select to reserve Not Null Attribute, Source Attribute, or Target Field Attribute.
    • Not Null Attribute: Keep the non-empty attribute values in the source data and Target Dataset edge object. If both the source data and the Target Dataset Edge object are Not Null Attribute, the attribute value of the source data edge object is retained.
    • Source Attribute: Holds the attribute value of the source field.
    • Target Field Attribute: Retain the attribute value of the Target Field.
  • Edge Match Union: Check the change check box to merge the source data object associated with the edge and the Target Dataset object, and append other objects of the source data to the Target Dataset.
  • Generate Edge Match Link Data: Select this check box to save the edge match guide describing the processing trajectory of the object end when the source data and the Target Dataset are matched as a Line Dataset.
  • Edge Match Link Data: When the Generate Edge Match Link Data check box is selected, Set the Dataset Name where Generate Edge Match Link Data is stored and the Datasource where it is located.
  After

  setting the above parameters, you can execute the Edgematching operation, and the splicing result is shown in the following figure:
