I used several sources. Granit, Exeter town conservation commission and other town sources.

When adding a nature preserve on Tinker Island, the Gulf of Maine tag was removed in error. It say it has no feature tag. Need help fixing. Not sure what it shoud be?

It may be that the nature preserve might go beyond the shores. This is the question. However, I was using parcel data that did appear to be a better shoreline than the original data. Being new to the mapping of nature preserves on existing islands, I am still learning. I think I have started doing what you said and tagging the existing island as a nature reserve. One question is the nature preserve blots out the island name when rendering after I do this. But I did see one that was rendered with the island name appearing and the nature preserve name along the side of the boundary. That was what I was hoping for but maybe I was doing something wrong or being to analytical about how it is dispalyed on the map.

It seems that looking at the school mapping throughout the US and in Maine, the school grounds carry the name if its only one school associated with the area. Then the building is just tagged as a school building. Its kind of a mish mash of practices. Not my intention to break things. It just looks weird that you would have two names appearing on the map (the area and the building). Guess coming from a more visual cartographic background, having duplicate names is clutter.

Not sure what is being asked but if something is wrong, just update to what you think it should be. Tags for this feature is ambiguous at best. Not an expert either. thanks
