Centroid Has No Polygon

Indicates that a centroid feature has been found that does not lie within a polygon. This type of error often is due to a “Line Not In Closed Loop” error; see following error messages:

Centroid Has Null-Geometry

Indicates, that the centroid has no geometry (no coordinates).

Line Not In Closed Loop

Indicates that the line does not meet the following condition: The edges of an area topology have to build a closed polygon. All lines that do not fulfill this condition are listed under this node.

The line is not part of a valid polygon. The reason for this error can be either of the following:

Lines Cross Or Touch

The edge crosses or touches another line.

Line Crosses Or Touches Self

Lines cross or touch each other.

Line Has Null-Geometry

The edge has no geometry (no coordinates).

Polygon Has Errors

Invalid polygons are saved in the system table _TSER. The reason for this error can be one of the following:

Line Has More Than {0} Vertices

The edge has many vertices.

Line Has Duplicated Sections

The edge has a section that has been digitized twice (mostly forth – back – forth).

Line Has Adjacent Points

The edge has two or more adjacent points that lie together closer than the tolerance value.

Two Or More Rings Touch

An outer and inner ring or two inner rings touch.

Coordinates are outside of the spatial extents.

The coordinates are outside of the spatial extents.

Polygon Has Multiple Centroids

The polygon has more than one centroid. Expand the polygon items to see the centroids.

Polygon Has Been Modified Outside Perimeter

The area of a polygon that lies outside, or partially outside the perimeter, has been changed, and the change exceeds the tolerance.
