- 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.
