To Match Map Edges

Maps that are digitized at different times or that use different coordinate systems can appear distorted at their edges. Edge matching creates a seamless join across two or more maps.

To match map edges

1. Open a drawing and attach the maps you want to match at edges.
2. Define a query to retrieve the objects to match:
   • Click Home tabData panelDefine Query. Find
   • Define a location condition with a buffer fence option. When defining the buffer fence, select the edge to match and specify a suitable buffer fence width.
   • You can also add a property condition to select objects on a specific layer.
3. Click Tools tabMap Edit panelClean Up. Find
4. On the Drawing Cleanup -Select Objects Page, click Select All. You can specify the layer(s) you want to use, for example, the layer containing road data, and anchor objects as needed. Click Next.
5. On the Select Actions Page, in the Cleanup Actions list, click Snap Clustered Nodes and then click Add.
6. In the Selected Actions list, click Snap Clustered Nodes. Under Cleanup Parameters, set Tolerance to a value just greater than the offset distance between objects. You can type a value in the Tolerance box or click Pick to specify the tolerance in the drawing.
7. Under Options, choose Automatically. Click Next.
8. In the Cleanup Methods Page, under Cleanup Method, select Modify Original Objects.
9. You can save your settings in a profile to use again later.
10. Click Finish to start the drawing cleanup operation.
11. In the Confirm Save Back dialog box, click Yes.

    The objects are now contiguous across the map edges. Repeat steps 4 - 11 for all other layers and objects in the edge matching part of the maps.

To save the edited objects back to the source drawings

1. Click Home tabData panelSave To Source. Find
2. Under What To Save, make sure Save Queried Objects is selected. Click OK.

   All the objects are now matched at their edges.
