Video Overview
Overview
Topology refers to the relationship between lines, points, and polygons. For more information about the concept of topology please visit this Wikipedia article. Map Suite offers a set of static Map Suite APIs relating to topology, along with an application to validate topology rules. Topology can be very useful in GIS as it allows users to clean up data or to modify geometries to comply with different rules and restrictions. Below is a list of all of the topology cases this sample covers:
Lines End Point Must Be Covered By Points
Lines Must Be Covered By Boundary Of Polygons
Lines Must Be Covered By Feature Class Of Lines
Lines Must Be Larger Than Cluster Tolerance
Lines Must Be Single Part
Lines Must Not Have Dangles
Lines Must Not Have Pseudonodes
Lines Must Not Intersect Or Touch Interior
Lines Must Not Intersect
Lines Must Not Overlap With Lines
Lines Must Not Overlap
Lines Must Not Self Intersect
Lines Must Not Self Overlap
Points Must Be Covered By Boundary Of Polygons
Points Must Be Covered By EndPoint Of Lines
Points Must Be Covered By Lines
Points Must Be Properly Inside Polygons
Polygons Boundary Must Be Covered By Boundary Of Polygons
Polygons Boundary Must Be Covered By Lines
Polygons Must Be Covered By Feature Class Of Polygons
Polygons Must Be Covered By Polygons
Polygons Must Be Larger Than Cluster Tolerance
Polygons Must Contain Point
Polygons Must Cover Each Other
Polygons Must Not Have Gaps
Polygons Must Not Overlap With Polygons
Polygons Must Not Overlap
Lines End Point Must Be Covered By Points
The ends of lines in one feature must be covered by points in another feature.
Lines Must Be Covered By Boundary Of Polygons
Lines in one feature must be covered by the boundaries of polygons in another feature.
Lines Must Be Covered By Feature Class Of Lines
Lines in one feature class must be covered by lines in another feature.
Lines Must Be Larger Than Cluster Tolerance
Cluster tolerance is the minimum distance between vertices of features. Vertices that fall within the cluster tolerance are defined as coincident and are snapped together.
Lines Must Be Single Part
Lines within a feature must only have one part.
Lines Must Not Have Dangles
The end of a line must touch any part of one other line or any part of itself within a feature.
Lines Must Not Have Pseudonodes
The end of a line cannot touch the end of only one other line within a feature. The end of a line can touch any part of itself.
Lines Must Not Intersect Or Touch Interior
Lines can only touch at their ends and must not overlap each other within a feature.
Lines Must Not Intersect
Lines can only touch at their ends and must not overlap each other within a feature.
Lines Must Not Overlap
Lines must not overlap any part of another line within a feature. Lines can touch, intersect, and overlap themselves.
Lines Must Not Overlap With Lines
Lines in one feature must not overlap any part of another line in another feature.
Lines Must Not Self Intersect
Lines must not cross or overlap themselves within a feature. Lines can touch themselves and touch, intersect, and overlap other lines.
Lines Must Not Self Overlap
Lines must not overlap themselves within a feature. Lines can touch, intersect, and overlap lines in another feature.
Points Must Be Covered By Boundary Of Polygons
Points in one feature must touch boundaries of polygons from another feature.
Points Must Be Covered By EndPoint Of Lines
Points in one feature must be covered by the ends of lines in another feature.
Points Must Be Covered By Lines
Points in one feature must be covered by lines in another feature.
Points Must Be Properly Inside Polygons
Points in one feature must be inside polygons of another feature.
Polygons Boundary Must Be Covered By Boundary Of Polygons
The boundaries of polygons in one feature must be covered by the boundaries of polygons in another feature.
Polygons Boundary Must Be Covered By Lines
Polygon boundaries in one feature must be covered by the lines of another feature.
Polygons Must Be Covered By Feature Class Of Polygons
The polygons in the first feature must be covered by the polygons of the second feature.
Polygons Must Be Covered By Polygons
Polygons in one feature must be covered by a single polygon from another feature.
Polygons Must Be Larger Than Cluster Tolerance
Cluster tolerance is the minimum distance between vertices of features. Vertices that fall within the cluster tolerance are defined as coincident and are snapped together.
Polygons Must Contain Point
Each polygon must contain exactly one point. Each point must fall within a polygon.
Polygons Must Cover Each Other
All polygons in the first feature and all polygons in the second feature must cover each other.
Polygons Must Not Have Gaps
Polygons must not have a void between them within a feature.
Polygons Must Not Overlap
Polygons of the first feature must not overlap polygons of the second feature.
Polygons Must Not Overlap With Polygons
Polygons of the first feature must not overlap polygons of the second feature.
