You can use this attribute in the style to produce a glowing effect where points are densely packed. It can range from 0 in the sparsest areas to 255 in the densest.

\fB\fC\-ai\fR or \fB\fC\-\-generate\-ids\fR: Add an \fB\fCid\fR (a feature ID, not an attribute named \fB\fCid\fR) to each feature that does not already have one. There is currently no guarantee that the \fB\fCid\fR added will be stable between runs or that it will not conflict with manually\-assigned feature IDs. Future versions of Tippecanoe may change the mechanism for allocating IDs.
