Gazetteer v2.0.0

[dasulit]

Proposing some changes for Gazetteer 2.0!

The main change is the addition of a category property derived from the existing tags. These higher-level categories help organize the geoJSON by grouping places together, and hopefully provide a clearer point of entry to gazetteer for cartographers.

Please see the script I used to process the data here: https://gist.github.com/dasulit/4c45db9dd583ed191c15aff39abb7f8e

Other changes to note:

• I removed a bunch of tags that I felt were a) already handled by other tags; b) proper nouns and therefore not in line with the generic tagging system; or c) not useful to map designers. I'm flexible with these deletions, I'd be happy to hear any of these tags are necessary and should be saved.
• I adjusted some tags that were close in name and meaning to other tags.
• If, after these tag adjustments, a place was left with no tags, I removed it from the FeatureCollection.
• I updated the version to 2.0.0 and added tests for category.

@samanpwbb and @nickidlugash for review!

@dasulit Looking good! A couple of things:

Did you decide against making the category values arrays? I do think this is important because a lot of the features fall under multiple categories.

The following deleted/combined tags are specific Mapbox Streets data layer names or values (or terms that represent numeric values), or otherwise useful, so I think we should keep them:

• cliff
• national capital
  • regional capital
  • rock
  • ski
  • state capital
  • landuse_overlay
  • wetland_noveg

Also, barrier does make more sense than barrier_line, but just noting that barrier_line is the actual name of the data layer.

@dasulit @nickidlugash how would it sound to:

1. Review that list of deleted tags, think about how to re-categorize them and the re-run the render script.
2. Save multi-category support for another PR and track multi-category support in an issue that we can add as a later enhancement. multiple categories will add a decent amount of complexity and will delay getting the first version of the cart-cam out.

Sounds good to me! I just amended my commit to reintroduce those tags. The places I removed them from were already categorized by other tags (with the exception of national capitals, which I tossed in with cities, and landuse_overlay, which folded in with landuse). Script updated too.

Noting that the successes and shortcomings of these tag categorizations are already starting to surface as I'm using the data in an interface. I think making some observations and decisions from some brief user (cartographer) testing with carto-cam would be helpful, and from there I can work out a gazetteer 2.1 PR.
