Merge or filter points that have a common attribute value and are spatially close

pimververgmail — Mon,11 Sep 2017 14:20:27 GMT

I have a couple of thousand points that have a number as attribute.Some of those points are

- close to each other

- also have the same number

Note: there are also points that have the same number but are far apart.

I want to merge all points that match both conditions into 1 point

So far I have set a neighbourfinder transformer,which groups the points by number and then finds the closest points (max 4).

But how do I merge the resulting related points into 1?

Any suggestions are welcome.

Kind regards,

NeighborFinder close candidate list - is is ordered?

When multiple neighbors to find are specified,is the resulting list ordered by proximity or not?That is,is the nearest neighbor at position 0 in the list,next nearest at position 1,and so on?

Aligning polylines

I have roads and trails in one shapefile (file A) and in a separate I have lines which show which trails are signposted (file B).Unfortunately the later is not very precise so it does not align well with the trail or road.Can I use FME to detect proximity and then create a new shapefile where this proximity is marked by "high-lighting" the relevant parts of the trails/roads in file A?
