Using just three of many datasets for my example, these latitude longitude points from three files represent three different price-points. I am going to combine the three datasets and wish to cluster them geographically–within some physical distance tolerance (?DBScan, K Nearest Neighbor, whatever you suggest). I have attached the Latitude and Longitude points and a base ID for each of the three groups here. I would love the GIS distance algorithm to automatically create/present the shapefiles (clusters) and assign the shapefile ID to each property, both as data and as a map image. From there I get to do all kinds of cool analyses. As always, any assistance, suggestions, or workflow you can offer is more appreciated than you know. group1.xlsx (8.6 KB) group2.xlsx (10.9 KB) group3.xlsx (11.6 KB) [map1] [map2] [map3]

GIS Clustering and Shapefile Creation

This one fell off my radar completely, sorry! Maybe this forum thread would be useful to you - it contains a nice workflow from @LukasS as well that makes use of the KNIME Spatial Processing Nodes extension.
