func ExtractGeohashesFromKML ¶

func ExtractGeohashesFromKML(kmlPath string, precision uint) (map[string]struct{}, error)

ExtractGeohashesFromKML parses the given KML file at kmlPath, extracts coordinate data from polygons, and generates geohashes with the specified precision.

kmlPath: The path to the KML file. precision: The desired geohash precision. Returns: A set of geohashes covering the KML-defined regions, or an error if parsing fails.

func GenerateGeohashesForPolygon ¶

func GenerateGeohashesForPolygon(polygons []structs.Polygon, precision uint) map[string]struct{}

GenerateGeohashesForPolygon generates geohashes that cover the entire polygon area

func GetInteriorPointByTriangulation ¶

func GetInteriorPointByTriangulation(polygon []structs.Coordinate) structs.Coordinate

GetInteriorPointByTriangulation returns an interior point of the polygon using triangulation.

func ParseCoordinates ¶

func ParseCoordinates(coordString string) []structs.Coordinate

ParseCoordinates parses the KML coordinates string into a slice of Coordinates

func PointInPolygon ¶

func PointInPolygon(point structs.Coordinate, polygon []structs.Coordinate) bool
