I am currently facing a challenge and am reaching out with the hope that someone can provide assistance.
I have a list of coordinates (latitude and longitude), and I would like to group together all connected coordinates within a radius of 500 meters. My attempts so far have not yielded a suitable solution. My current approach involves assigning a unique identifier to these connected coordinates, but I am also open to alternative suggestions.
I have attached an example file to illustrate the issue. Could you please help me find a solution within KNIME to group these coordinates?
Thank you very much in advance for your support! Your assistance is highly appreciated.
Perhaps the most simple thing you can try is Hierarchical Clustering node. So it will try to put the closest object according to your threshold into the clusters. 1 degree is 111.32 kilometers, in your case 500 meter would be around 0.005 degrees. So you can use this values as a threshold.
I prepared simple workflow for you.
Otherwise you can have a look at the Geospatial extension, perhaps it has a better way to group the points within a radius. However I am not that experienced with that extension.
