Hello All,
I have two datasets. The first dataset is excel files that show citizens' residence the second dataset is GTFS. I want to find the number of residents who live within 400 meters from the existing bus stops. I would appreciate the help or advice. Thanks
As far as I an tell from the description, you will need these trasformers:
Bufferer to create the 400 m buffer area
PointOnAreaOverlayer to count the residents in the buffer area.
This is a great site to find the description of the transformers: Transformer Help

To create points from attributes you can use the VertexCreator transformer.
My youtube tutorial on how to buffer points in fme may be helpful to answer this question:
Vertex Creator in Residences Lat/Long then connect it in PoinOnAreaOverlayer point entrance.
Vertex creator in Lat/Long of bus stop then geographicbufferer to 400 m then connect it in area entrance of pointonareaoverlayer.
The points will have the Id of the areas (Buffers) and a overlaps of 1 (inside polygon) or 0 (out of buffers). If you have buffer overlapping you may have overlaps greater than 1.
The areas (buffer) will have the amount of points on it in the overlaps field
