Distance Meaning

[minh5]

Thanks for this neat tool! Im curious, what is the meaning of the distance? For instance, what does it mean to have a cluster distance of 0.0005, does this mean that the cluster is 5 miles or that mean that points within .0005 miles will constitute a cluster?

The distance depends on the used reference system.

For metrical systems the real distance is calculated as cluster_distance * pixel_size_in_m at given scale. For EPSG:3857 at TMS scale level 10 (1:607.883) you have a pixel size of 152.87m. So real distance (cluster_distance = 50) ist 7643.5m. So the clusters are around (not exactly!) 7.5km away.

For lat/lon systems the distance is given in degrees. The real distance depends on where you're data is located on earth.
