# version 0.9-5 * Only when package `s2` >= 1.0.1 is available: support for spherical geometry operators (predicates, transformers, measures, nearest point/feature) for geographic coordinates in package `s2` is now by default switched off, and can be switched on by `sf_use_s2(TRUE)`; see https://www.r-spatial.org/r/2020/06/17/s2.html and vignette sf7. It is planned to be switched on by default in sf 1.0-0. * drop Z and/or M coordinate in `st_as_s2()`, with message * geometry predicates and transformers gain an ... argument to pass `s2::s2_options()` * `dplyr::select()` now ensures the geometry column sticks to the back rather than the front of the data frame; #1425 * `dplyr::rename()` now preserves the active geometry column even when it is renamed; #1431 * proj units query adjusted to PROJ 7.1.0 release; #1434 # version 0.9-4 * empty geom generators take care of XYZ etc dim; #1400 * `write_sf` and `read_sf` no longer warn when reading tables without geometries * `st_write` writes non-spatial tables when given a plain `data.frame` or `tbl_df`; #1345 * the default for `stringsAsFactors` in `st_read` and `st_sf` is `FALSE` for R version >= 4.1.0 * the sf method for `dplyr::select()` supports renaming the geometry column; #1415 # version 0.9-3 * `st_is_valid` is a generic * Windows CRAN binaries use GDAL 3.0.4, PROJ 6.3.1 and GEOS 3.8.0, thanks to Jeroen Ooms' rwinlib work; #1275 * `plot.sf` gains an `extent` argument to set the extent (xlim, ylim) of the plot; `extent` must be an object with an `st_bbox()` method, such as an `sf` or a `stars` object; #1193 # version 0.9-2 * `st_axis_order(TRUE)` gives and error if GDAL has version < 2.5.0 * loading PROJ units `link`, `us_in`, `ind_yd`, `ind_ft`, and `ind_ch` into the udunits database is no longer done at package load time, but when function `sf_add_proj_units()` is called. * fix line sampling for small densities; #1365 * `sf_project` handles `crs` objects when PROJ version is below 6 using proj.4 string representations. * avoid using `isFALSE` in `st_write()`; #1342 * fix regression in `gdal_utils("translate", ...)`; #1339 # version 0.9-1 * fix an invalid read bug in `st_m_range`; #1332 * `st_crs(4326) == st_crs("+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs")` returns `TRUE` for GDAL >= 3.0, irrespective authority compliance of axis order; see #1331 and https://github.com/ropensci/scrubr/issues/34 * `sf_project` has a parameter `authority_compliant` to return coordinates in "visualisation order"; when `TRUE` it returns coordinates in authority compliant axis order (e.g. EPSG:4326 latitude longitude); default is `st_axis_order()`. * fix test for Solaris and certain GDAL/PROJ versions * fix error reading category table through GDAL; https://github.com/r-spatial/stars/issues/245 # version 0.9-0 * see r-spatial blog post: https://www.r-spatial.org/r/2020/03/17/wkt.html * modify `crs` objects to reflect our post-proj4string world (#1146; #1225): crs objects contain two fields, `input` with the user input (if any), and `wkt` with a well-known-text (or WKT2) representation of the coordinate reference system. `crs` objects have a `$` method to dynamically retrieve the `epsg` (integer) or `proj4string` representation, using e.g. `x$epsg`. * support for PostGIS 3 using WKT and the new-style `crs` objects; #1234, #1303, #1308 by @etiennebr * `st_write_db` and `st_read_db` are defunct. Use `st_write` and `st_read` instead. * `st_write` uses `append`, replacing (and deprecating) argument `update`; `st_write` fails when a layer already exists and `append` has not been set explicitly to `TRUE` (append) or `FALSE` (overwrite); #1266 * `st_proj_info` was renamed into `sf_proj_info`; `sf_proj_info` can get and set the PROJ data search path and use of CDN; #1277 * adapt to new `dplyr` version; https://github.com/tidyverse/dplyr/issues/4917 * `st_sample` is a generic * write `stars` rasters with wkt info, rather than proj4strings * when GEOS >= 3.8.0, `st_make_valid` is provided by `sf` rather than by `lwgeom` #989 * allow for single-sided buffers for linear geometries; #1001 * add `st_reverse` methods to reverse points in a linestring (requires GEOS >= 3.7.0); #1246 * `st_make_grid` returns grid cells or points that intersect with the target geometry, not its bounding box; #1260 * allow for PROJ >= 7; #1254 # version 0.8-1 * `st_as_sf.map` no longer requires `maptools` and `sp`; dropped dependency on maptools. * work around a bug in 6.0.0 <= PROJ < 6.3.1: replace `+init=epsg:XXXX ...` strings with the `XXXX` EPSG integer, to work around a bug in PROJ; see https://github.com/OSGeo/PROJ/pull/1875 and links therein. If `...` arguments are present, raise a warning that these are ignored. * `st_as_sf.map` no longer requires `maptools` and `sp`; drop dependency on maptools. * conversion between `spatstat` classes `owin`, `ppp` and `psp` and `sf` classes no longer use `maptools`; #1204 * `gdal_utils` processes open options `-oo` and `-doo` properly; https://github.com/ITSLeeds/geofabric/issues/12 * `st_sample` directly interfaces `spatstat` sampling methods, e.g. `type = "Thomas"` calls `spatstat::rThomas` after converting input arguments (window) and converts returned `ppp` object to `sf`'s `POINT` geometries; #1204 with help from Ege Rubak and Jakub Nowosad * `sf_project` gains an option `keep = TRUE` to return `Inf` values for points not projectable; #1228 * support `vctrs` methods for geometry list columns; this makes `unnest` work again (#1172); #1196 by Lionel Henry * `st_as_sf.pq_geometry` converts binary geom columns from RPostgres::dbGetQuery; #1195 * `st_cast` can convert `MULTICURVE` to `MULTILINESTRING`; #1194 * `st_read` gains a parameter `wkt_filter` for spatially filtering the features to be read; #1192 * `st_area()` and `st_length()` handle `+to_meter` argument in PROJ strings; #1170 * add `st_filter` generic for filtering on spatial features only; #1148 * a new UBSAN error in `wkb_read` was resolved; #1154, #1152 * new method `st_shift_longitude` to re-center data for a Pacific view. #1218 * output of `st_as_text()` with `MULTIPOINT` has nested parentheses around points. E.g., `MULTIPOINT ((0 0), (1 1))` instead of `MULTIPOINT (0 0, 1 1)`; #1219, #1221 # version 0.8-0 * fix tests for PROJ 6.2.0 not accepting +units= * fixes for tidyr 1.0-0 release; attempt to port `nest.sf` and `unnest.sf`; #1068, #1145 * `gdal_utils` better closes connections after use; #1143 * `st_write` gains a `drivers` options, to limit the drivers attempted; #1142 * rather than replacing, `st_write` and `write_sf` append to an existing layer if `update=TRUE`; #1126 * improve plotting of `POSIXct` and `Date` attributes (`Date` requiring classInt >= 0.4-2) * `NULL` geometries read by GDAL are returned as empty geometries; #1119 * `gdal_utils('rasterize', ...)` accepts non-existing destinations, defined by e.g. resolution and extent options (see #1116 for an example), and overwrites if needed (see #1136 for an example) * add Dan Baston as contributor; #1120 and many others * in addition to `NULL`, `st_sfc()` also converts `NA` values into empty geometries; #1114. * `st_join` is a generic # version 0.7-7 * `plot()` handles `POSIXct` values in legend * constructor functions like `st_linestring()` check and break on `NA` coordinates; #1101, #1102 # version 0.7-6 * have examples of `st_write` write only to the temporary R session directory # version 0.7-5 * `as(x, "Spatial")` gives a proper error message on empty geometries; #1093 * `st_cast` takes care of empty polygons; #1094 * `st_nearest_*` functions warn in case they are used with geographic coordinates; #1081 * `st_union` no longer segfaults on zero row `sf` objects; #1077 * `st_transform` no longer breaks on zero row `sf` objects; #1075 * when PROJ >= 6.1.0 is available and sf comes with datum files (as is the case with statically linked Windows and OSX CRAN binaries), `PROJ_LIB` is no longer temporarily overwritten, but the PROJ C api is used to set the datum path; #1074, suggested by Jeroen Ooms * sf compiles against GDAL 3.x and PROJ 6.1.0, using the new `proj.h` interface; #1070 * `st_distance` returns `NA` for empty geometries, rather than 0; #1055 # version 0.7-4 * add example on how voronoi polygons can be tied back to the points they contain; #1030 * `st_difference(x, y)`, with `x` an `sfc` with zero feature geometries, returns `x`; #1024 * don't reset (base) plot device when `add = TRUE` * `==` and `!=` return `NA` when one of the operands is an empty geometry; #1013 * `st_intersects` is a generic * drop requiring `proj_api.h` in favor of `proj.h`, this enables compatibility to PROJ 6.0.0 and GDAL 2.5.0-dev; #988 * fix regression in binary predicates introduced in #855; #999 reported by Barry Rowlingson * fix bug in `gdal_utils` util `warper` on certain GDAL/OS combinations; https://github.com/r-spatial/stars/issues/117 * `c.sfc` ignores the type (class) of empty `sfc` objects when choosing the result type; #985, #982 * rename the default value for `distance` to `"Euclidean"`, rather than `"distance"` in `st_distance` # version 0.7-3 * add argument `exact` to `st_sample`, for defaulting to `FALSE`; #896 * fixed n-ary `st_difference` for cases where geometries are entirely contained in others; #975, by Jonathan Marshall * faster `Ops.sfc`, added `st_normalize`; #973 by Thomas Lin Pedersen * new grob constructor for sfc objects; #971 by Thomas Lin Pedersen; add Thomas as contributor * add `group_split` and `group_map` methods for `sf` objects (experimental); #969 * make `st_interpolate_aw` a generic; * argument `col` for `plot` of `GEOMETRY` `sfc`'s is `NA` (open) for (multi) polygon geometries # version 0.7-2 * feature IDs are no longer returned as names on the geometry list column, but optionally returned by `st_read` as attribute column; #812 * when plotting multiple attributes, plot.sf adds a (single, common) key if `key.pos` is set * precision can be specified in distance units; #901 * support log-scale in color legend by setting `logz` to `TRUE` in `plot.sf` * `st_intersects` etc. will prepare `y` when `y` is polygons and `x` is points; #885 by Dan Baston * `st_write` (and `write_sf`) returns its first argument, invisibly; #889 # version 0.7-1 * fix bug that broke n-ary `st_intersection` on platforms using clang; #867 # version 0.7-0 * adds several interfaces to GDAL functions, meant to be used by package `stars` * `st_read` receives a `query` argument that can run queries against OGR datasets; #834, by Barry Rowlingson and Michael Sumner * `read_sf` no longer first creates tibbles from `data.frame`s, but creates them directly; #853, db propagation by Etienne Racine * check difference between compile-time and run-time GEOS versions;

#755 * add reference to the [R Journal article](https://journal.r-project.org/archive/2018/RJ-2018-009/index.html) in CITATION # version 0.6-3 * move dependency `RPostgreSQL` from Imports: back to Suggests: * `st_centroid.sf` and `st_point_on_surface.sf` also warn if attributes are not constant over geometries. * `summarise` allows the user to define geometries for summaries; #714, by Kirill Mueller * `plot.sf` emits a warning if `col` does not have length 1 or `nrow(x)`, and requires `pal` (rather than `col`) to set a palette for factors. * `plot.sf` provides control over legend keys using `key.length` and `key.width`, decrease default key length; #731 * `sgbp` objects receive an `as.data.frame` method; #715 # version 0.6-2 * GDAL read/write supports logical variables; #722 * add `st_crop` to simplify cropping objects with a rectangular area; #720 * fix bug in `[<-` when columns are added to an `sf` object; #718 * use dynamic registration of S3 methods, similar to how hms does this; #710 by Kirill Mueller * (partially) address writing GPKG to network drive, writing to temp file first; #628 * add Kirill Mueller as contributor * `st_make_grid` is faster; #708, by Dan Baston * `st_read` and `st_write` are generic, with methods for directly reading from and writing to database connections; `st_read_db` and `st_write_db` are deprecated; #558, thanks to Etienne Racine @etiennebr * Package `RPostgreSQL` moved from Suggests to Imports * restore compatibility with GDAL 2.0.x versions (which won't have `gdal_utils`); #686 * `read_sf` can also read tables without geometry; #684, by Andy Teucher # version 0.6-1 * method `distinct` works; #669, #672 * `+`, `-`, `*` and `/` for pairs of geometries (`sfg`, `sfc`) return geometric union, difference, intersection and symmetric difference, respectively. * `st_cast` from `MULTIPOLYGON` to `MULTILINESTRING` should work properly; #660 * all Rcpp interfaces needed by package `stars` have been moved into `sf`; pkg `stars` is R-only, and only `sf` needs linking to GDAL. * `gdal_utils()` interfaces the 9 gdal utils using the C++ API * improve resetting (base) plots; add `reset = FALSE` in a call to `plot` to enable adding to plots that have a legend * `st_read` returns a `data.frame` when a table contains no geometries, rather than giving an error; it does emit a warning in this case. See https://stat.ethz.ch/pipermail/r-sig-geo/2018-February/026344.html * move `pillar` from `Imports:` to `Suggests:` * update to the new rwinlib distribution of gdal (adds JPG2000); #639 * speed up computation of centroids for largest polygon; #623 * add `st_as_sfc.raw` method * Bugfix: binary operations (`st_intersection`, `st_difference`, etc) no longer fail when operating on data frames of class `"tbl_df"` with common column names; #644 # version 0.6-0 * add `pillar` to Imports: to provide method for printing WKT geometries in tibbles * `st_as_text`, and subsequently `format` and `print`, use argument `digits` (or `options(digits = n)`) to control the number of digits used for printing coordinates; default is `options("digits")`, which is typically 7. * `st_is_within_distance` works with geographic coordinates * `st_cast` from `MULTIPOLYGON` to `MULTILINESTRING` no longer changes the number of features/feature geometries, but conversion from `MULTIPOLYGON` to `LINESTRING` (typically) does; #596 * `st_distance` for long/lat geographic coordinates uses `lwgeom`, accepting all geometry types; argument `dist_fun` is deprecated as a consequence, and distance calculations are different from those in sf versions 0.5-5 or earlier; #593 * add package `lwgeom` to Suggests; `st_area`, `st_length`, `st_distance`, `st_segmentize` for long/lat CRS use package `lwgeom` instead of `geosphere`; #593 * `st_length` returns zero for polygon-type geometries; #593 * if present, add units of attribute to default plot title; #591 * add `unnest` method, which depends on `tidyr` > 0.7-2; #570 PR by @karldw * add `largest` option to `st_join` to get largest intersection match only; #547, by @tiernanmartin * change default maximum number of feature to print to 10, controllable by `options(sf_max_print)`; #556 * add `Hausdorff` (and `Frechet` for those with GEOS 3.7.0) as options to `st_distance`; add `par` for densified versions * add `st_snap`, for snapping geometries to other geometries, within a tolerance * make `st_wrap_dateline` a generic, with methods for `sf`, `sfc` and `sfg`; #541 * `plot.sf` and `st_as_grob` (used by ggplot2) are robust against misspecified ring directions (holes that have the same direction as the exterior rings), by using `rule = "evenodd"`; #540 * functions depending on `liblwgeom` (`st_make_valid`, `st_geohash`, `st_plit`) have been moved to their own package, https://github.com/r-spatial/lwgeom; argument `use_gdal` of `st_transform` has been deprecated, instead one can use `lwgeom::st_transform_proj`; sf no longer tries to link to liblwgeom; #509, #537, #487 * `st_read`, `st_sf` and `st_sfc` gain a parameter `check_ring_dir` (default: `FALSE`) that checks ring directions and corrects to: exterior counter clockwise, holes clockwise, when seen from above. * get rid of `classInt::classIntervals` warning if number of unique values is smaller than the number of breaks asked for # version 0.5-5 * have `classInt` in Imports:, to not break other package checks * add vignettes 5: plotting sf objects and 6: miscellaneous; #324 * add (default) color key to `plot.sf` if single map is plotted, contributed by @hughjonesd; #528 * `st_as_sfc` can read EWKT; #530 * argument `max.plot` takes its default from `options(sf_max.plot=n)`, if present; #516 * `plot.sf` gets an arguments `pal` to specify a color palette function; #526 * `plot.sf` gets arguments `breaks` and `nbreaks`; add support for `classInt::classIntervals` styles for finding class intervals (using `breaks`) * add `st_as_sf` methods for `ppp`, `lpp` and `psp` objects from spatstat. * allow for direct route to proj.4 ignoring GDAL (requiring liblwgeom); #509, #511 * add `print` method for `crs` objects; #517 * `sf_extSoftVersion` reveals whether GDAL was linked to GEOS; #510 * better check input of `st_polygon`; #514 * add `st_node`, similar to `rgeos::gNode` * support for reading `OFTInteger64List` fields; #508 * sparse geometric binary predicate lists have a class, `sgbp`, and attributes `region.id` and `predicate`; #234, #524 * prevent `st_split` from stopping the R session; #492 * `st_intersection`, `st_union` and so on also print a message when used directly on long/lat coordinates; #496 * add `rep` method for `sfc` objects * comparing two `crs` objects uses the GDAL function `IsSame`; #180 * add `st_collection_extract`, which, given an object with geometries of type `GEOMETRY` or `GEOMETRYCOLLECTION`, returns an object consisting only of elements of the specified type; by Andy Teucher, #482 * `st_write` exports GeoJSON with UTF-8 encoding on Windows; #444 * move package methods from Imports: to Depends: ; #478 * deal better with precision setting and propagation; #476 * fix bug in `st_layers` in case layers have no geometry; #334 * clarify argument `envelope` in `st_voronoi`; #474 * change aggregate to make it return the same geometry as 'by', padding attributes with NA where needed; #453 # version 0.5-4 * fix compatibility problems introduced by `tidyr` 0.7-0 using rlang magic * convert path names to UTF-8 in `st_read`, `st_write` and `st_layers`;

`dplyr::bind_cols` or `st_sf(data.frame(sf, df))` work for binding `data.frame`s to an `sf` object. * `st_segmentize()` and `st_line_sample()` accept units arguments * document problem reading shapefiles from USB drives on OSX; #252 * improve docs of `st_is_valid` and `st_make_valid`; #296 * coercing `sf` to `data.frame` works better; #298 * `st_line_sample` gains argument `sample` to specify the points t.b. sampled; #299 #300 thanks to @joethorley * add compatibility to upcoming dplyr 0.6.0; #304 #42 * write GDAL fields by name, not by number, fixing a KML problem #308 * `st_write` gains arguments `delete_layer` and `delete_dsn` to allow overwrite capability #307 #274 * `write_sf` defaults to `delete_layer=TRUE`, silently overwriting layers if they're already present * compatibility with GDAL 2.2beta0; #303; #309 * replace `st_write_db` with a version that is fast for large datasets (#285), thanks to Josh London * take out more memory leaking examples in tests * the `aggregate` method for `sf` objects assumes the `by` argument to be identical to that of `stats::aggregate` * `st_wrap_dateline` wraps (cuts up) geometries crossing the antimeridian, such that they no longer cross it. # version 0.4-1 * restore 3.3.0 and c++11 requirement * `st_read` respects time that is read as UTC * `st_write` writes time always as UTC, since GDAL does not have a mechanism to define local timezones other than "unknown" or "local" * `st_length` works for POINT and MULTIPOINT (returning 0); POLYGON and MULTIPOLYGON are converted to MULTILINESTRING before computing length, thus giving polygon perimeter (#268) * `st_write` has `update` depend on driver; for databases, the default is `TRUE`, otherwise `FALSE` (it refers to update of the database, and not to overwriting the table in the database, this will by default not succeed); #274 * `st_read` supports reading objects with multiple geometry columns #257 #255 * support writing (exporting) objects with non-standard columns, such as `units` or `POSIXlt` #264 * catch dependencies on GEOS 3.3.5 (hence no 0.4-0 CRAN binary for MacOSX) #260 # version 0.4-0 * have `st_is_valid` catch corrupt geometries too, returning `NA` in that case (requiring GEOS 3.5.0) * add `st_make_valid`, only available when sf was linked to `liblwgeom` * add `st_coordinates` method, returning coordinates matrix with indexes * remove `unlist.sfg` * add `as.matrix.sfg`; have as.matrix.sfg add indexes to coordinates * add `st_bind_cols` method * improve handling features that can't be projected * support uniform sampling over polygons on the sphere * add `st_sample`, for sampling points on multipoints, linestrings, or polygons * add `c` method for `sfc` objects * import and export `magrittr::%>%` * support ggplot'ing geometrycollections * drop C++11 requirement, allowing build for older R versions * add `st_proj_info`, modelled after `rgdal::projInfo` * overwriting datasets with `st_write` is no longer allowed; update=TRUE appends to them, permitted the driver supports appending. * `st_write` gains an argument, `update`, which when `TRUE` will try to append to existing datasets (#204) * added list of corresponding function for migration from sp, rgdal and rgeos to sf at https://github.com/edzer/sfr/wiki/migrating * remove deprecated `st_list` * rename `st_makegrid` to `st_make_grid`, and `st_linemerge` to `st_line_merge` * add NEWS.md file (#207) * faster conversion of `data.frame` into `POINT` `sf` object, using `st_as_sf` (Michael Sumner) * `rbind` method for `sf` objects keeps coordinate reference system # version 0.3-4, Feb 6, 2017 * add `st_contains_properly` spatial predicate * GEOS functions (geometry operations) accept XYZ geometries (and ignore Z) * make `prepared = TRUE` the default for all geometry binary operations # version 0.3-2, Feb 4, 2017 * add user interrupt checks in all GEOS geometry operations * make `st_graticule` do something useful for polar projections * make `st_graticule` return `NA` labels when labels are useless * add `merge.sf` methods to merge `sf` object and `data.frame` (#193) * add `st_join` for table joins based on (user-defined) spatial predicates * add `dplyr`-style non-spatial joins for `sf` objects (`left_join`, `full_join` etc.) (#193) * allow for multiple non-gathered variables (#196) * add missing meridian to `st_graticule` (#198) # version 0.3-1, Jan 31, 2017 * add `merge` method (#193) * `st_graticule` for laea (#198) * allow `st_buffer` with feature-dependent buffer distance (#197) * have `spread` return an `sf` object (#196) * clarify `overwrite = TRUE` in write docs * fix `st_as_sf.map` (#194) * add `prepared` arg to spatial binary predicates, to speed up large intersections * add `st_voronoi` interface (requires that lib GEOS >= 3.5.0) * add `st_as_sf` methods for `map` objects (library maps) * add RStudio project file * have `st_bbox` return a `bbox` object which has an `st_crs` method * rename `st_drop_zm` into `st_zm`, for general more handling of Z and M * allow for 3D coordinates returned, when `+proj=geocent` (#172; #103) * fix `NA_integer_` handling in shapefiles I/O (#184) * add and fix `st_agr` API, to set and get attribute-to-geometry relationships # version 0.2-8, Jan 5, 2017
