You can also use the Snap geoprocessing tool (requires ArcGIS for Desktop Standard or ArcGIS for Desktop Advanced) in the Editing toolbox. Use snapping to modify polygon edges and vertices manually using the editing tools.However, you need to be careful that you enter the smallest cluster tolerance possible so you don't inappropriately collapse or merge features. Integrate can help fix both slivers and gaps. You can use the Integrate geoprocessing tool to make polygon edges and vertices coincident.You can run the Check Geometry and Repair Geometry tools, which can help find and fix short segments, null geometry, and other problems that could result in sliver polygons.You can also look for Must Be Larger Than Cluster Tolerance errors, which are polygons small enough to collapse during the process of validating the topology. You can apply Must Not Overlap and Must Not Have Gaps rules to find polygons that either overlap each other or have gaps between them. Geodatabase topology is the most efficient, automated, and thorough means of finding and fixing these errors. With an ArcGIS for Desktop Standard or ArcGIS for Desktop Advanced license, you can set up a geodatabase topology.You can also try some of the other alignment tools available when editing. This includes the shape to align to, which layers are updated, and the tolerance.
#What can be used to clean snap on or mac tools update#
Align To Shape works well to update multiple layers when you want some control over the parameters used in the alignment. Use Align To Shape on the Advanced Editing toolbar to adjust features in certain layers to a line you create.There are several general ways you can clean up these errors: Slivers and gaps keep your dataset from forming a continuous fabric and should be identified and fixed as appropriate. Tiny sliver polygons or gaps between polygons often result from creating new polygons without using snapping or editing shared boundaries without a topology. Removing slivers or gaps between polygons
