sedona_read_wkb {apache.sedona} | R Documentation |
Create a generic SpatialRDD from a hex-encoded Well-Known Binary (WKB) data source.
sedona_read_wkb(
sc,
location,
wkb_col_idx = 0L,
allow_invalid_geometries = TRUE,
skip_syntactically_invalid_geometries = TRUE,
storage_level = "MEMORY_ONLY",
repartition = 1L
)
sc |
A |
location |
Location of the data source. |
wkb_col_idx |
Zero-based index of column containing hex-encoded WKB data (default: 0). |
allow_invalid_geometries |
Whether to allow topology-invalid geometries to exist in the resulting RDD. |
skip_syntactically_invalid_geometries |
Whether to allows Sedona to automatically skip syntax-invalid geometries, rather than throwing errorings. |
storage_level |
Storage level of the RDD (default: MEMORY_ONLY). |
repartition |
The minimum number of partitions to have in the resulting RDD (default: 1). |
A SpatialRDD.
