In apache.sedona: R Interface for Apache Sedona

(Deprecated) Create a typed SpatialRDD from a shapefile or geojson data source.

Description

Constructors of typed RDD (PointRDD, PolygonRDD, LineStringRDD) are soft deprecated, use non-types versions

Create a typed SpatialRDD (namely, a PointRDD, a PolygonRDD, or a LineStringRDD)

• sedona_read_shapefile_to_typed_rdd: from a shapefile data source

• sedona_read_geojson_to_typed_rdd: from a GeoJSON data source

Usage

sedona_read_shapefile_to_typed_rdd(
  sc,
  location,
  type = c("point", "polygon", "linestring"),
  storage_level = "MEMORY_ONLY"
)

sedona_read_geojson_to_typed_rdd(
  sc,
  location,
  type = c("point", "polygon", "linestring"),
  has_non_spatial_attrs = TRUE,
  storage_level = "MEMORY_ONLY",
  repartition = 1L
)

Arguments

sc	A spark_connection.
location	Location of the data source.
type	Type of the SpatialRDD (must be one of "point", "polygon", or "linestring".
storage_level	Storage level of the RDD (default: MEMORY_ONLY).
has_non_spatial_attrs	Whether the input contains non-spatial attributes.
repartition	The minimum number of partitions to have in the resulting RDD (default: 1).

Value

A typed SpatialRDD.
