Hello, I have AIXM 5 reader in my workspace. When I load geometry, I got 2D points. I need to get elevation from geometry trait. My problem is that the geometry property extractor does not offer me any traits for export. Where can be a mistake?

Here is my data in Data Inspector:

How have you set parameters in the GeometryPropertyExtractor?

In this answer they comment about using Deaggregator and then the GeometryPropertyExtractor.

Not sure if it could work for you.

Does every point surely have the trait called "elevation"? I'm afraid that the trait is missing in some features.

Good note. I did not think so. Next time I check it in advance. This time is the elevation property everywhere.

hmm, sounds strange. By the default Geometry XQuery, the GeometryPropertyExtractor should extract the specified trait without de-aggregating, if every geometry has the trait...

It is quite strange. In GeometryPropertyExtractor is still any traits to choose, but I have elevation in attributes after translation.

These screenshots demonstrate how the transformer with the default Geometry XQuery works for aggregate geometries. In the sample data, 4 features didn't have "elevation" trait.

I tried the same. I still can´t choose any trait to extract, but now it works without deaggregator. I think of some mistake in reader setting or in input data.

 

 

If you want test original data: obst1809.xml

I was able to extract the "elevation" trait from your sample data, without Deaggregator. I've not touch any parameter in the AIXM5 reader.
