I took a look at the data set, and we'd need to do some research before importing on what the various "ManagementType" might correspond to in terms of boundary=protected_area protect_class=* tagging. In addition, the data set has a large number of parcels where adjacent parcels are identical except for FC_Key (intended to be a unique ID for the parcel?), County and YOE. (I don't know what YOE means - it appears to be "Year Of" something - and there are dates in both the future and the past, so I don't think it's "year of expiration"). In some cases, the dividing lines appear to be township and range lines, but in many places, they're too irregular to be simple PLSS lines and aren't meander lines either, so I suspect they simply represent former lot boundaries. Most parcels appear to be about three sections in size, and given that they're consistently elongated in an E-W direction, may simply be consecutively numbered sections. (If you don't know what township, range and section mean in this context, read https://en.wikipedia.org/wiki/Public_Land_Survey_System). Given the large number of parcels that are named alike, we probably need to look at coalescing adjacent ones. I suspect the division is just to keep accounting straight for parcels that were acquired at different times or from different former owners, and not something we ought to be replicating in OSM. _______________________________________________ Talk-us mailing list Talk-us@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-us
