OSM Conflator

OSM Conflator is a Python package that allows you to conflate GeoJSON features with OpenStreetMap (OSM) data. It helps you identify and modify features in a GeoJSON dataset that intersect with OSM data, providing a convenient way to update properties or perform other actions based on the conflation results.

Installation

You can install OSM Conflator using pip:

pip install osmconflator

Usage

Here's an example of how to use OSM Conflator in your Python code:

from osmconflator import conflate_geojson

geojson_str = '{"type": "FeatureCollection", "features": ... }'

conflated_geojson = conflate_geojson(geojson_str)

print(conflated_geojson)

This output will have input features with conflated properties of duplicate and intersect (boolean) .

In the above example, conflate_geojson is the main function provided by OSM Conflator. It takes a GeoJSON string as input, performs conflation with OSM data, and returns an GeoJSON string with problems of duplicate and overlapping.

Options :

• Pass remove_conflated=True argument to conflate_geojson function to get clean geojson without duplicate or overlap problem.

my_cleaned_geojson = conflate_geojson(geojson_str,remove_conflated=True)

Features Supported :

Currently conflation for following osm features are supported :

• Buildings

Example :

from osmconflator import conflate_geojson

my_geojson = {
    "type": "FeatureCollection",
    "features": [
        {
            "type": "Feature",
            "properties": {},
            "geometry": {
                "coordinates": [
                    [
                        [83.98097353206458, 28.203326601546905],
                        [83.98097353206458, 28.203239142020323],
                        [83.98110284724493, 28.203239142020323],
                        [83.98110284724493, 28.203326601546905],
                        [83.98097353206458, 28.203326601546905],
                    ]
                ],
                "type": "Polygon",
            },
        },
        {
            "type": "Feature",
            "properties": {},
            "geometry": {
                "coordinates": [
                    [
                        [83.97980503615179, 28.20407835951059],
                        [83.97980503615179, 28.204017832398932],
                        [83.97987683972957, 28.204017832398932],
                        [83.97987683972957, 28.20407835951059],
                        [83.97980503615179, 28.20407835951059],
                    ]
                ],
                "type": "Polygon",
            },
        },
    ],
}

conflated_geojson = conflate_geojson(my_geojson)
print(conflated_geojson)

Output :
