- varunayan.util.geojson_utils.convert_to_geojson(json_data: Dict[str, Any]) Dict[str, Any][source]#
Convert various JSON formats to valid GeoJSON.
This function tries to intelligently convert different JSON structures to proper GeoJSON format based on the content.
- Parameters:
json_data – The parsed JSON data
- Returns:
A valid GeoJSON dictionary
- Raises:
ValueError – If the JSON cannot be converted to GeoJSON
- varunayan.util.geojson_utils.create_geojson_from_bbox(west: float, south: float, east: float, north: float) Dict[str, Any][source]#
Create a GeoJSON polygon from bounding box coordinates.
- Parameters:
west – Western longitude
south – Southern latitude
east – Eastern longitude
north – Northern latitude
- Returns:
A GeoJSON Feature with a Polygon geometry
- varunayan.util.geojson_utils.create_temp_geojson(geojson_data: Dict[str, Any], request_id: str) str[source]#
Create a temporary GeoJSON file with the provided data.
- Parameters:
geojson_data – Valid GeoJSON data
request_id – Unique identifier for the request (used in filename)
- Returns:
Path to the created temporary file
- varunayan.util.geojson_utils.extract_coords_from_geometry(geometry: Dict[str, Any]) List[List[float]][source]#
Extract all coordinates from a GeoJSON geometry object.
- varunayan.util.geojson_utils.get_bounding_box(geojson_data: Dict[str, Any]) Tuple[float, float, float, float][source]#
Extract the bounding box (west, south, east, north) from a GeoJSON object.
- Parameters:
geojson_data – A GeoJSON object (loaded as a Python dictionary)
- Returns:
Tuple of (west, south, east, north) coordinates
- varunayan.util.geojson_utils.is_valid_geojson(json_data: Dict[str, Any]) bool[source]#
Check if the provided JSON data is valid GeoJSON.
- Parameters:
json_data – Parsed JSON data
- Returns:
True if it’s valid GeoJSON, False otherwise
- varunayan.util.geojson_utils.load_json_with_encoding(file_path: str) Dict[str, Any][source]#
