There are many topology rules you can implement in your geodatabase, depending on the spatial relationships that are most important for your. Errors in GIS data mean any information or decisions based on that data are flawed. Geodatabase topology provides an automated, rule-based solution to. Topology in ESRI® ArcGIS® allows you to model spatial relationships between feature model. Topology errors are violations of the rules that you can easily.

Requires that a polygon in one feature class or subtype must share all of its area with polygons in another feature class or subtype. Note that you can use the Edit tool and move the line inside the polygon feature if you do not want to delete it. The Snap fix can be applied to one or more Must Coincide With errors. This rule is used when there are lines from two layers that should never cross each other or in cases where the intersection of lines should only occur at endpoints, such as streets and railroads.

Geodatabase topology rules and fixes for point features—ArcGIS Pro | ArcGIS Desktop

This is useful arxgis the point features help support the boundary system, such as boundary markers, which must be found on the edges of certain areas. This is useful when the point features are related to polygons, such as wells and well pads or address points and parcels.

Requires that a line feature must touch lines from the same feature class or subtype at both endpoints. Requires that the interior of polygons in one feature class or subtype must not overlap with the interior of polygons in another feature class or subtype.

This fix can be applied to one or more Must Not Have dangles errors.

This rule is used when area features need to have line features that mark the boundaries of the areas. This fix can be applied to one or geodxtabase selected Must Not Overlap With errors.

Requires that line features not overlap themselves. This rule is used when two systems of classification are used for the same geographic area, and any given point defined in one system must also be defined in the other. This fix can be applied to one or more Must Not Intersect With errors. Point errors are created where points from the first feature class or subtype are not covered by points from the second feature class or rulds.

ArcGIS Desktop Help – Topology rules

Requires that each polygon contains one point feature and that each point feature falls within a single polygon. Rulee area in the first feature class that is not covered by polygons from the other feature class is an error. Requires that lines not overlap with lines in the same feature class or subtype.

They arcgls cross or touch themselves but must not have coincident segments. Note that you can snap the point to the line by setting edge snapping to the line layer, then moving the point with the Edit tool. This is usually when the areas have one set of attributes and their boundaries have other attributes.

Lines can cross or intersect but cannot share segments. This fix can be applied to one or more Must Be Inside errors. The polygons can share edges or vertices. Endpoint Must Be Covered By.

In instances where this rule is violated, the original geometry is left unchanged. The Split fix splits the line features that cross one topooogy at their point of intersection. Geodatabase topology rules allow you to define relationships between features in the same feature class or subtype or between two feature classes or subtypes. Polygon rules Line rules Point rules.

This is useful for cases where points must be covered by other points, such as transformers must coincide with power poles in electric distribution networks and observation points must coincide with stations. Each parcel might be defined by one or more line features that store information afcgis their length or the date surveyed, and every parcel should exactly match its arcgie. Points in one feature class or subtype must be inside polygons of another feature class or subtype.

Point errors are created where the points are outside or touch the boundary of the polygons. The Create Feature fix creates a new line feature from the boundary segments of the polygon feature generating the error.

Points topllogy one feature class or subtype must be covered by the ends of lines in another feature class or subtype. Requires that polygons of one feature class or subtype must be contained within polygons of another feature class or subtype.
