Table: (\#tab:sfs-st-cast)Geometry casting on simple feature geometries (see Section 2.1) with input type by row and output type by column. Values like (1) represent the number of features; NA means the operation is not possible.
Abbreviations: POI, LIN, POL and GC refer to POINT, LINESTRING, POLYGON and GEOMETRYCOLLECTION. The MULTI version of these geometry types is indicated by a preceding M, e.g., MPOI is the acronym for MULTIPOINT.
