How do I import GeoJSON files for use in Google Earth Engine Code Editor?
I have generated some points of interest with my database with SQL to geoJSON.
geojson:

I would like to import this geojson to my code editor on Google Earth Engine. Looking in the docs (assets manager), GEE accepts assets as raster images, shapefiles (.shp, shx, dbf, prj).
Also, I found the import to feature collection via fusion tables, but it still needs shapefiles.
I have found some geojson to shapefile conversors, though I need a way to directly import my geojson to a feature collection on GEE. Is that possible?
Answer
You can also import GeoJSON geometry objects directly using, for example, this format for a MultiPolygon:
feature_geometry =
{
'type': 'MultiPolygon',
'coordinates': [[[
[-120, 35],
[-120.001, 35],
[-120.001, 35.001],
[-120, 35.001],
[-120, 35]
]]]
}
That is identical to the GeoJSON specification (source):
{
"type": "MultiPolygon",
"coordinates": [
[
[ [102.0, 2.0], [103.0, 2.0], [103.0, 3.0], [102.0, 3.0], [102.0, 2.0] ]
],
[
[ [100.0, 0.0], [101.0, 0.0], [101.0, 1.0], [100.0, 1.0], [100.0, 0.0] ],
[ [100.2, 0.2], [100.8, 0.2], [100.8, 0.8], [100.2, 0.8], [100.2, 0.2] ]
]
]
}
Of course, you can also read this data in from a GeoJSON file:
import json
data = json.loads(geojson_file)
For a nice simple wrapper, there is the pygeoj library, but JSON data is handled well natively in Python and of course in JS.
