问题
I am trying to store spatial data in the form of geojson,csv files and shape files into elasticsearch USING PYTHON.I am new to elasticsearch and even after following the documentation i am not able to successfully index it. Any help would be appreciated.
sample geojson file :
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"properties": {
"ID_0": 105,
"ISO": "IND",
"NAME_0": "India",
"ID_1": 1288,
"NAME_1": "Telangana",
"ID_2": 15715,
"NAME_2": "Telangana",
"VARNAME_2": null,
"NL_NAME_2": null,
"HASC_2": "IN.TS.AD",
"CC_2": null,
"TYPE_2": "State",
"ENGTYPE_2": "State",
"VALIDFR_2": "Unknown",
"VALIDTO_2": "Present",
"REMARKS_2": null,
"Shape_Leng": 8.103535,
"Shape_Area": 127258717496
},
"geometry": {
"type": "Polygon",
"coordinates": [
[
[
79.14429367552918,
19.500257885106404
],
[
79.14582245808431,
19.498859172536427
],
[
79.14600496956801,
19.498823981691853
],
[

]
]
]
}
}
]
}

You must separate the GeoJson features into (1) geometry and (2) properties/attributes parts. You cannot index GeoJson features and feature collections directly (see documentation), only the geometry part is supported as a field type.
So you final indexable document would look somewhat flattened:
{
"ID_0": 105,
"ISO": "IND",
"NAME_0": "India",
"ID_1": 1288,
"NAME_1": "Telangana",
"ID_2": 15715,
"NAME_2": "Telangana",
"VARNAME_2": null,
"NL_NAME_2": null,
"HASC_2": "IN.TS.AD",
"CC_2": null,
"TYPE_2": "State",
"ENGTYPE_2": "State",
"VALIDFR_2": "Unknown",
"VALIDTO_2": "Present",
"REMARKS_2": null,
"Shape_Leng": 8.103535,
"Shape_Area": 127258717496,
"geometry": {
"type": "Polygon",
"coordinates": [
[
[
79.14429367552918,
19.500257885106404

]
]
}
}
