Can't open MRF file geometry with FeatureReader

Hello,

 

I am currently trying to open a MRF file with FeatureReader.

 

Usually, when i use FeatureReader, there is a particular output port created on the transformer.

In this case, I only have the following output ports :

  • Schema
  • Generic
  • Initiator.

Those outputs do not contain any geometry.

 

When configuring the transformer, I do the following actions :

  • I set the format to "Meta Raster Format (MRF)"
  • I set the dataset
  • I go into "Parameters...", and I set the Feature Type Name to "From format name"
  • I set "Feature Types to read" to "mrf"
  • I set "Features to read" to "Schema and data features"
  • I set "Accumulation mode" to "Only use result".

If I run this transformer, it does not fail, but there is no geometry output.

If I use a MRF reader it works fine : when opening the inspector, I can see my data and click it. Sadly, this is not the process logic, I must use a FeatureReader.

 

Did I forget to set some parameter ? How do I get the geometry output ?

 

Here are somme screenshots of my parameters in case it helps :

I ended up doing it this way :

  • In the MRF Parameters, I set "FeatureType Name" to "From subdataset name"
  • and then set "Feature Type to read" to "Z0".
