For NLCD, should this also be classified as developed, or should it be dropped / classified differently?

Developed, Open Space- areas with a mixture of some constructed materials, but mostly vegetation in the form of lawn grasses. Impervious surfaces account for less than 20% of total cover. These areas most commonly include large-lot single-family housing units, parks, golf courses, and vegetation planted in developed settings for recreation, erosion control, or aesthetic purposes.

[nvkelso]

Keep as developed kind for now, and we can set kind_detail later.

The CCI-LC legend is here (and is simpler than the CORINE land cover nomenclature): https://maps.elie.ucl.ac.be/CCI/viewer/download/CCI-LC_Maps_Legend.pdf

I should have enough info to map this.

40 - "Mosaic natural vegetation (tree, shrub, herbaceous cover) (>50%) / cropland (<50%)" - thoughts? cultivated? 150-153 - "sparse" - barren?

[nvkelso]

Wow, these are looking great!

The thing I do like about MODIS is it's more appropriately generalized for lower zooms without needing as much processing to get there. So please keep it in the mix.

[mojodna]

Definitely. It's been good for uncovering some edge cases as well.

Another downside of MODIS is that it requires loading data from more files for lower zooms (where ESACCI-LC is a single, much larger file).

[mojodna]

Mappings documented here: https://github.com/mojodna/marblecutter-land-cover/blob/master/README.md#classification-correlation

If/when they change, the catalog metadata needs to be updated, e.g.

UPDATE land_cover
SET recipes = recipes || '{"colormap": {"0": 10, "1": 40, "2": 40, "3": 40, "4": 40, "5": 40, "6": 50, "7": 50, "8": 70, "9": 70, "10": 70, "11": 90, "12": 80, "13": 20, "14": 80, "15": 10, "16": 30, "254": 0, "255": 0}}'

            <edomvd>
Characterized by erect, rooted, herbaceous hydrophytes
(excluding mosses and lichens) that are present for most
of the growing season in most years. Perennial plants
usually dominate these wetlands. All water regimes are
included except those that are sub-tidal and irregularly
exposed.

            <edomvd>
Characterized by substrates lacking vegetation except for
pioneering plants that become established during brief
periods when growing conditions are favorable. Erosion and
deposition by waves and currents produce a number of
landforms, such as beaches, bars, and flats, all of which
are included in this class.

Includes widespread and diverse Algal Beds in the Marine

characterized by a wide range of sediment depths and
textures. They occur in both the sub-tidal and inter-tidal
Subsystems and may grow to depths of 30 m (98 feet).
This class includes kelp forests.
