sedona_read_shapefile_to_typed_rdd {apache.sedona} | R Documentation |
(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 |
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.
