normalize_geometry

Standardize geometry orientation and order for consistent geospatial analysis. Input a WKT geometry to receive a normalized version as output.

Instructions

Normalize the orientation/order of a geometry using shapely.normalize. Args: geometry: WKT string of the geometry. Returns: Dictionary with status, message, and normalized geometry as WKT.

Implementation Reference

src/gis_mcp/shapely_functions.py:537-558 (handler)

The core handler function for the 'normalize_geometry' tool. It takes a WKT geometry string, normalizes it using Shapely's normalize function, and returns the result as WKT in a status dictionary. Registered via the @gis_mcp.tool() decorator.

@gis_mcp.tool()
def normalize_geometry(geometry: str) -> Dict[str, Any]:
    """
    Normalize the orientation/order of a geometry using shapely.normalize.
    Args:
        geometry: WKT string of the geometry.
    Returns:
        Dictionary with status, message, and normalized geometry as WKT.
    """
    try:
        from shapely import wkt, normalize
        geom = wkt.loads(geometry)
        normalized = normalize(geom)
        return {
            "status": "success",
            "geometry": normalized.wkt,
            "message": "Geometry normalized successfully"
        }
    except Exception as e:
        logger.error(f"Error in normalize_geometry: {str(e)}")
        return {"status": "error", "message": str(e)}

src/gis_mcp/shapely_functions.py:82-93 (registration)

Resource handler that lists 'normalize_geometry' among the available Shapely utility operations, indicating its registration in the MCP toolset.

@gis_mcp.resource("gis://operations/shapely_util")
def get_shapely_util_operations() -> Dict[str, List[str]]:
    """List available Shapely utility/advanced operations."""
    return {
        "operations": [
            "snap_geometry",
            "nearest_point_on_geometry",
            "normalize_geometry",
            "geometry_to_geojson",
            "geojson_to_geometry"
        ]
    }

src/gis_mcp/shapely_functions.py:538-544 (schema)

Function signature and docstring defining the input schema (geometry: str) and output format (Dict with status, geometry WKT, message). Serves as the tool schema in this decorator-based MCP implementation.

def normalize_geometry(geometry: str) -> Dict[str, Any]:
    """
    Normalize the orientation/order of a geometry using shapely.normalize.
    Args:
        geometry: WKT string of the geometry.
    Returns:
        Dictionary with status, message, and normalized geometry as WKT.
