GeoDataFrame

class GeoDataFrame<T : WithGeometry>(val df: DataFrame<T>, val crs: CoordinateReferenceSystem?)

A data structure representing a geographical DataFrame, combining spatial data with an optional Coordinate Reference System (CRS).

Integrates with Kandy for plotting:

The type parameter extending WithGeometry, indicating the presence of a geometry column.

Constructors

constructor(df: DataFrame<T>, crs: CoordinateReferenceSystem?)

val crs: CoordinateReferenceSystem?

The coordinate reference system associated with the data, if any.

The underlying DataFrame containing geometries.

fun applyCrs(targetCrs: CoordinateReferenceSystem): GeoDataFrame<T>

Transforms the geometries to a specified Coordinate Reference System (CRS).

fun GeoDataFrame<*>.bounds(): ReferencedEnvelope

Computes the bounding envelope for all geometries in a GeoDataFrame, considering the specified coordinate reference system (CRS).

open operator override fun equals(other: Any?): Boolean

open override fun hashCode(): Int

Creates a new GeoDataFrame by applying transformations to the underlying DataFrame.

fun GeoDataFrame<*>.toSimpleFeatureCollection(name: String? = null, singleGeometryType: Boolean = false): SimpleFeatureCollection

Converts the GeoDataFrame to a SimpleFeatureCollection.

open override fun toString(): String

Writes this GeoDataFrame into a GeoJSON file.
