I have a folder full of unzip (.shp) mixed shape files Points, Lines, and Polys. Can I read in only the points somehow?? If not can anyone recommend a way to restrict to schema to only that of the point shapes, which I have found two different ones so far?

Hi @dbklingdom, I would try this.
- Read schema features from the target *.shp files with the Schema (Any Format) reader. Expose "fme_geomatry{}" and "fme_dataset" in the "schema" feature type.
- Use the Tester to select only schema features having value "fme_point" in the "fme_geometry{0}".
- Read the point Shapefile datasets using the FeatureReader with setting "fme_dataset" to the Dataset parameter.

Hello @dbklingdom ,
A quick way that I can think of would involve using a Merged Filter on your Shape reader(if the point shapefiles have a different naming convention you could filter here eg: '*_point'). Alternatively, if you read in all of the Shapefiles and use a GeometryFilter. You could then allow only the point features to be passed on to the rest of the translation. I hope that helps.
Documentation that may help can be found here:

https://docs.safe.com/fme/2017.1/html/FME_Desktop_Documentation/FME_Transformers/Transformers/geometryfilter.htm
I hope that helps.

How to query schema in FeatureReader for geometry type. I have 12 different schema's and maybe more coming from shapes. i would like to use the Schema's of the points, but cannot seem to get fme_geo or shape_geo in the Schema output to tester.

Hey many thanks for the replies. Now on the other side how do we setup FeatureReader to output the Schema and data?? If not there I have sent schema to listExploder, but am have trouble setting the schema up to be reader by the Dynamic Writer. IS it a single field? what is the Concatination syntactic? Thx
