feature-collection w/ one feature

[jessekrubin]

why is examples/problematic_geometries/problematic_multitype_geometry_with_just_one_geometry.geojson problematic?

The geojson spec says a feature collection can have 0+ features

Hey, yes you are correct. It's not invalid (not in the invalid category), but listed here as a "problematic" example (problematic category). As a reminder that this case should be handled in your code/tool, which some don't and sometimes fail when feeding in this type.

@chrieke thanks for your reply!

I found 2 more problems.

• examples/invalid_structure/invalid_geometry_geometrycollection_nested.geojson is totally valid -- you can have nested geometry collections
• examples/invalid_structure/invalid_geometry_geometrycollection_single.geojson is also valid -- you can have just one geometry w/ in a geom-collection

structurally invalid

• examples/invalid_geometries/invalid_less_three_unique_nodes.geojson should be moved to invalid-structure as it is structurally invalid -- polygon needs at least 4 points regardless of uniqueness
• examples/invalid_geometries/invalid_incorrect_geometry_data_type.geojson should also be moved invalid-structural -- structure is invalid for line string

mixed feelings

• examples/problematic_structure/invalid_crs_defined.geojson I have mixed feelings on crs in geojson as it is technically deprecated, however it is extremely useful when working with other crs-s (no idea how to pluralize that)

Thanks for checking it out and the comments and suggestions! Will have a look on the weekend and get back!
