Error: “the number of points is less than required for feature”,

Hi,

 

 

sounds like an invalid geometry. Set an inspection point just before the output feature type (circled in red) and inspect the number of coordinates of the first feature that goes through.

 

 

You could also insert a CoordinateCounter with a Tester to check for e.g. polygons with < 3 vertices or lines with < 2 vertices.

 

 

Also make sure that the coordinates aren't so close to one another that they're getting conflated into a single point by ArcSDE (distance < tolerance).

Many thanks guys for the help,

 

 

Neither the “CoordinateCounter” nor the “create aggregates :No” has resolved the issue.

 

 

 

 

 

 

Applying the “check geometry” in the ArcGIS shows the features that have problems despite the fact all of them have area, length and number of vertices more than two.

 

 

 

 

 

 

This way I’m back to the first circle: the FME has no sufficient tools to repair the Geometry to be accepted by the enterprise geodatabase layer.

 

 

 

I’m wondering why I should face all of these problem just to extract the roads layer from the boundary and landuse

 

 

Roads = Boundary – Landuse

 

 

If the Boundary and Landuse are valid then how come the result (Roads) is not valid?

Thanks Takashi.

 

 

Deleting small polygons will definitely cause a problem as donuts\\holes\\gaps are generated within the LanduseAndRoads layer. In this case, if the Boundary is re-derived from this layer (LanduseAndRoads), gaps will be created inside this layer (this might occur at the level of ArcGIS for further analysis).

 

 

 

 

I got help from GIS expert at enterprise level. He advised to apply the “integrate” tool in the ArcGIS to resolve the issue of self-intersecting. It works as a charm till now. The power of the “integrates” is that it repairs the polygons without deleting them (and thus it doesn’t leave gaps).

 

 

 

 

 

 

 

 

 

 

What might be the equivalent tool for the “integrate” (of the ArcGIS) in the FME?

 

 

Thanks Takashi.

 

 

Now, I’ll try to go for your previous valuable suggestion. To remove the slivers (small areas). Gaps\\holes\\donuts can be refilled again with correct geometry by the “Eliminate Polygon Part” tools available in the ArcGIS.

 

 

 

 

 

Do we have such tool (“Eliminate Polygon Part”) in the FME?

Thanks Sami.

 

 

best
