This needs to be handled.

Example

geojson <- '{
  "type": "FeatureCollection",
  "features": [{
    "type": "Feature",
    "geometry": {
      "type": "Point",
      "coordinates": [102.0, 0.5, 100]
    },
    "properties": {
      "prop0": "value0"
    }
  }, {
    "type": "Feature",
    "geometry": {
      "type": "LineString",
      "coordinates": [
        [102.0, 0.0],
        [103.0, 1.0],
        [104.0, 0.0],
        [105.0, 1.0]
        ]
    },
    "properties": {
      "prop0": "value0",
      "prop1": 0.0
    }
  }, {
    "type": "Feature",
    "geometry": {
      "type": "Polygon",
      "coordinates": [
        [
          [100.0, 0.0],
          [101.0, 0.0],
          [101.0, 1.0],
          [100.0, 1.0],
          [100.0, 0.0]
          ]
        ]
    },
    "properties": {
      "prop0": "value0",
      "prop1": {
        "this": "that"
      }
    }
  }]
  }'

TODO

• geojson_validate.cpp - validate_points() will need to accept 2 <= x <= 4 sizes

Now works (currently in jsonify branch)

sf <- geojsonsf::geojson_sf( geojson )

sf
# Simple feature collection with 3 features and 2 fields
# geometry type:  GEOMETRY
# dimension:      XYZ
# bbox:           xmin: 100 ymin: 0 xmax: 105 ymax: 1
# epsg (SRID):    4326
# proj4string:    +proj=longlat +datum=WGS84 +no_defs
#                         geometry  prop0           prop1
# 1          POINT Z (102 0.5 100) value0            <NA>
# 2 LINESTRING (102 0, 103 1, 1... value0               0
# 3 POLYGON ((100 0, 101 0, 101... value0 {"this":"that"}
