Question

Dynamic component PointCloudFilter

Badge

Hi all

I´m working with a point cloud with the following schema

x|y|gridnum|col0|col1|col2|.....|colN

 

10|22|121212|12|23|.....|234

 

10|22|121212|0|12|.....|234

 

The number of components will vary and I can´t tell a fixed number

As output I want to remove the 0 values from the col(x) components

 

10|22|121212||12|.....|234

I´m using an iterator to go through all the components

Using PointCloudFilter I´m achieving it but only with fixed components.

 

I can also use a user parameter to set component. But again, I cannot update modify.

 

As I cannot use attributes in PointCloudFilter, Is there any way to update the value of the user parameter dynamically within the workspace? I´ve also considered JobSubmitter but I don´t have FME Server....

I think that an iterator is needed because I can´t say in advance how many components I will have.

Thanks so much in advance

Hi @txalaparta,

Have you tried the RasterCellCoercer (Output Cell Geometry = Points) with Extract Nodata Values set to no?

Hope this helps,

Itay

Hi Itay

Thanks for the quick replay.

In this case the points come from already "cleaned" rasters. So, there shouldn´t be any NoData points.

This case is all about reformating the output. I did it first reading each point in the point cloud and then with a StringReplacer but it takes forever comparing to PointCloud transformers available in FME

Correct me if I didn´t understand what you meant.

Thanks again anyway.
