DEFINITELY USE THIS FOR NOW!!!

All states available. Seems to be most accurate in dense areas and less in rural / suburbs. Although most data is at a moderate level of granularity.

Work on these categories:

Administration Areas(Boundaries): Level 02 = National Level 06 = County Level 08 = Town

Coastline

Water, Waterways

Buildings (these seem more accurate in dense urban areas, many missing pieces in rural areas)

Roads, Railways, railway stations,

Powerlines: point file marks location of many telephone wire poles and creates an electric wire flow across the state.

There isn't a great tree cover map here we will need to add that from somewhere else. Some data is patchy but it should provide us with a decent amount of site specific data.

@JGravelin Hey look I mentioned you in a comment.

If you can assemble a list of data types for land use data (population, housing units, etc) that are important, I can focus on integrating those first :dancers:
