mappyfile-geojson

A mappyfile plugin to convert GeoJSON to inline Mapfile features. Useful for adding dynamically created features (from web services, user created features), to a map.

import mappyfile
import mappyfile_geojson
# will soon be available to import as
# from mappyfile.plugins import geojson as mgeojson

gj = geojson.load(fn)
l = mappyfile_geojson.convert(gj)
print(mappyfile.dumps(l))

Converts:

{
  "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
  }
}

to:

LAYER
    EXTENT 102.0 0.0 105.0 1.0
    STATUS ON
    TYPE LINE
    PROCESSING "ITEMS=prop0,prop1"

        POINTS
            102.0 0.0
            103.0 1.0

Can calculate extent of input features, with optional buffer
Multipart features currently not implemented

Nested properties are not supported
