The reimport of NYS DEC Lands that I proposed this spring is now complete, except as noted below. Now would be a good time to check that I got it right.
I am aware of the following issues that need to be resolved before I call the import 'complete.' (1) I have not imported a fair number of parcels in the Long Island pine barrens. The reason is that local mappers have in many cases reused the nodes marking the parcel boundaries as edges of polygons that specify further land uses, or land covers (wood, scrub, wetland, meadow, etc.) In many cases, these appear to have been attempts to tag for the renderer, since inspection of aerial photographs shows land cover inconsistent with the tagging (natural=wood on what is obviously a brownfield site or a tidal flat, for example). This will require rather a lot of hand work to reconcile, and it's in an area where I don't have recent "boots on the ground" experience. If some local mappers from Suffolk County are willing to step forward and help me, that would be a tremendous relief. I can put up a .osm file with the DEC data as it should appear; other tagging (such as natural=*, landuse=*, related tags) obviously has to be reconciled with what's already there. (2) All the Long Island parcels, with the exception of the Ridge Conservation Area, need a mechanical edit to replace 'access=yes' with 'access=permit permit:website=http://www.dec.ny.gov/outdoor/7815.html.' I was unaware of this restriction when I started the import, and put Long Island on hold when I learnt about it, but there are a fair number of parcels already imported that need to be revised. I can come up with a script to identify them. (3) There are areas that comprise multiple separated parcels where a glitch in the import resulted in duplication of the multipolygon relation. Northern Montezuma Wildlife Management Area is the only one that I'm aware of, but I'm working up a script to audit the entire import and report duplicates. (4) Wildlife Management Areas exist that are not the current incarnation of the former State Game Farms. It would be a good idea to tag all Wildlife Management Areas with 'protection_object=habitat' rather than the current 'protection_object=hunting;fishing'. I fixed a couple of these manually, but want to do a mechanical edit to replace the rest. (5) I want to add leisure=nature_reserve to the landuse=aquaculture and boundary=protected_area that is present on the state fish hatcheries. This is not exactly a lie, since the land is protected, and if it is no longer used as a hatchery, it would revert to the default of 'state forest.' It's consciously tagging for the renderer, since there's otherwise nothing there that renders at all. (6) A number of parcels on the Hudson enjoy Federal as well as State protection, as the Hudson River National Estuarine Research Reserve. I need to finish researching which those are, and create a super-relation for them. (7) Many website=* links are dead or go to incorrect places. I have a script written already to enumerate the parcels that link to a website whose title differs significantly from the parcel name. These need to be inspected and better links found, if possible. (Failing anything else, links to the correct DEC regional office.) This is work that I could share out fairly easily, if anyone else wants to participate. (8) I have wikipedia= links for only a few of the most prominent sites. I'm sure that there are others with a Wikipedia presence, and searching for them could be partially automated. This is a low-urgency job, and again could be shared out pretty easily. On the whole, this reimport went considerably better than I expected. There were a few glitches that had to be corrected by stopping the import, doing mechanical edits, and resuming the import from where it left off, but on the whole the process was extremely smooth. In the vast majority of cases, there was no incompatible editing done since the initial import, so it was merely, "out with the old, in with the new." A check in JOSM for conflicting data took no more than a few seconds. (The other end of the spectrum was that a great many islands in the Adirondacks had to be drawn and added to their respective lakes. This got quite tedious indeed.) Thanks to all who helped with this! Kevin
