Details

Feature objects:

• A feature object must have a member with the name "geometry". The value of the geometry member is a geometry object as defined above or a JSON null value.

• A feature object must have a member with the name "properties". The value of the properties member is an object (any JSON object or a JSON null value).

• If a feature has a commonly used identifier, that identifier should be included as a member of the feature object with the name "id".

Examples

# point -> feature
x <- '{ "type": "Point", "coordinates": [100.0, 0.0] }'
point(x) %>% feature()

# multipoint -> feature
x <- '{"type": "MultiPoint", "coordinates": [ [100.0, 0.0], [101.0, 1.0] ] }'
multipoint(x) %>% feature()

# linestring -> feature
x <- '{ "type": "LineString", "coordinates": [ [100.0, 0.0], [101.0, 1.0] ] }'
linestring(x) %>% feature()

# multilinestring -> feature
x <- '{ "type": "MultiLineString",
 "coordinates": [ [ [100.0, 0.0], [101.0, 1.0] ], [ [102.0, 2.0], [103.0, 3.0] ] ] }'
multilinestring(x) %>% feature()

# add to a data.frame
library('tibble')
tibble(a = 1:5, b = list(multilinestring(x)))
