conn argument defaults now to NULL.
This parameter is not mandatory anymore in spatial operations, and it
will be handled internally. The argument has been moved after
x, y, and function-mandatory arguments
(#9).
ddbs_write_vector() allows to create a temporary
view with the argument temp = TRUE, which is much faster
than creating a table (#14).
ddbs_read_vector() uses internal optimizations with
geoarrow making it much faster (#15).
The spatial functions allow now to have either an sf
or a DuckDB table as input (x) and/or output
(name = NULL or name != NULL) (#19).
The crs and crs_column arguments are
deprecated and will be removed in duckspatial v1.0.0. This
change aligns with planned native CRS support in DuckDB, scheduled for
v1.5.0 (expected February 2025) (#7).
Affine functions: ddbs_rotate(),
ddbs_rotate_3d(), ddbs_shift(),
ddbs_flip(), ddbs_scale(), and
ddbs_shear() (#37).
ddbs_boundary(): returns the boundary of geometries
(#17).
ddbs_concave_hull(): new function to create the
concave hull enclosing a geometry (#23).
ddbs_convex_hull(): new function to create the
convex hull enclosing a geometry (#23).
ddbs_create_conn(): new convenient function to
create a DuckDB connection with spatial extension installed and
loaded.
ddbs_drivers(): get list of GDAL drivers and file
formats supported by DuckDB spatial extension.
ddbs_join(): new function to perform spatial join
operations (#6).
ddbs_length(): adds a new column with the length of
the geometries (#17).
ddbs_area(): adds a new column with the area of the
geometries (#17).
ddbs_distance(): calculates the distance between two
geometries (#34).
ddbs_is_valid(): adds a new logical column asserting
the simplicity of the geometries (#17).
ddbs_is_valid(): adds a new logical column asserting
the validity of the geometries (#17).
ddbs_make_valid(): makes the geometries valid
(#17).
ddbs_simplify(): makes the geometries simple
(#17).
ddbs_bbox(): calculates the bounding box
(#25).
ddbs_envelope(): returns the envelope of the
geometries (#36).
ddbs_union(): union of geometries (#36).
ddbs_combine(): combines geometries into a
multi-geometry (#36).
ddbs_quadkey(): calculates quadkey tiles from point
geometries (#52).
ddbs_exterior_ring(): returns the exterior ring
(shell) of a polygon geometry (#45).
ddbs_make_polygon(): create a POLYGON from a
LINESTRING shell (#46).
ddbs_predicate(): spatial predicates between two
geometries (#28).
ddbs_intersects(), ddbs_crosses(),
ddbs_touches(), …: shortcuts for e.g.:
ddbs_predicate(predicate = "intersects") (#28).
ddbs_transform(): transforms from one coordinates
reference system to another (#43).
ddbs_as_text(): converts geometries to well-known
text (WKT) format (#47).
ddbs_as_wkb(): converts geometries to well-known
binary (WKB) format (#48).
ddbs_generate_points(): generates random points
within the bounding box of x (#54).
Spatial predicates: spatial predicates are all
included in a function called ddbs_predicate(), where the
user can specify the spatial predicate. Another option, it’s to use the
spatial predicate function, such as ddbs_intersects(),
ddbs_crosses(), ddbs_touches(), etc.
All functions now have a parameter quiet that allows
users to suppress messages (#3).
Spatial operations now don’t fail when a column has a dot (#33).
Added some vignettes (#42).
ddbs_filter(): uses intersects for
ST_Intersects instead of
intersection.
ddbs_filter(): doesn’t return duplicated
observations when the same geometry fulfills the spatial predicate in
more than one geometries of y (#50).
ddbs_read_vector(): gains a new argument
clauses to modify the query from the table (e.g. “WHERE …”,
“ORDER BY…”)ddbs_list_tables(): lists table schemas and tables
inside the database
ddbs_glimpse(): check first rows of a table
ddbs_buffer(): calculates the buffer around the
input geometry
ddbs_centroid(): calculates the centroid of the
input geometry
ddbs_difference(): calculates the geometric
difference between two objects
ddbs_intersection(): overwrite argument defaults to
FALSE instead of NULL
Better schemas management. Added support for all functions.
