gdalraster 2.1.0

[ctoney]

Features / enhancements

Raster

• pixel_extract(): support optional point IDs in the first column of an input data frame and add argument as_data_frame (pixel_extract(): support optional point IDs in the first column of an input data frame and add argument as_data_frame #751)
• performance improvement for plot_raster() via col_tbl (performance improve for display via col_tbl #735 thanks @mdsumner)

Vector

• add write support for field domains (Add write support for field domains #738, Field domains: support coded values field domain as a two-column data frame of (codes, values) #739)
• GDALVector$getFieldDomain(): a coded values domain is now returned as a two-column data frame of (codes, values) instead of character vector of "CODE=VALUE", a breaking change but the return value was not previously documented. The returned field domain definition now aligns with the specification added under the ogr_define help topic in Add write support for field domains #738

Geometry API

• add g_boundary(): compute the boundary of input geometry, wrapper of OGR_G_Boundary() (Add g_boundary(): compute the boundary of a geometry #727)
• add g_convex_hull(): compute convex hull for input geometries, wrapper of OGR_G_ConvexHull() (Add g_convex_hull(): compute convex hull for input geometries #726)
• add g_delaunay_triangulation(): return a Delaunay triangulation of the vertices of the input geometry, wrapper of OGR_G_DelaunayTriangulation() (Add g_delaunay_triangulation(): return a Delaunay triangulation of the vertices of the input geometry #729)
• add g_set_3D()/g_set_measured(): add/remove the explicit Z/M coordinate dimension on the input geometries, wrappers of OGR_G_Set3D()/OGR_G_SetMeasured() (Add g_set_3D() and g_set_measured() #743)
• add g_is_ring(): tests whether a geometry is a ring, TRUE if the coordinates of the geometry form a ring by checking length and closure (self-intersection is not checked), otherwise FALSE (OGR_G_IsRing())
• support one-to-many input (this-to-others) in binary predicate functions and in g_distance() (Geom API: support one-to-many input (this-to-others) in binary predicate functions and in g_distance() #728)
• g_transform(): performance improvement when multiple input geometries (g_transform(): performance improvement when multiple input geometries #745)
• g_envelope(): add argument as_3d, wrapper of OGR_G_GetEnvelope3D() in the GDAL Geometry API (g_envelope(): fix order of xy coordinates in the returned envelope vector(s) and add argument as_3d #724)
• fixes and improvements in handling of NULL geometries (Geom API: fix the handling of OGR NULL geometries #732)
• minor fixes and improvements to input validation and error handling (Geom API: minor fixes and improvements to input validation and error handling #737)

Spatial Reference System API

• add srs_to_projjson(), wrapper for OSRExportToPROJJSON() in the GDAL Spatial Reference System API (Add srs_to_projjson(), wrapper for OSRExportToPROJJSON() in the GDAL Spatial Reference System API #721)
• srs_to_wkt(): add argument gcs_only, wrapper for OSRCloneGeogCS() in the GDAL SRS API

Coordinate transformation

• transform_bounds(): support multiple input bounding boxes given as rows of a matrix or data frame (transform_bounds(): support multiple input bounding boxes given as rows of a matrix or data frame #744)

Bug fixes

• g_envelope(): fix the order of xy coordinates in the returned envelope(s), fixes #725 a breaking change
• pixel_extract(): fix input validation for xy_srs

Internal

• improve input validation for the ogr_manage functions (Improve input validation for ogr_manage functions #749)
• add tests in tests/testthat/test-gdal_create.R for the the create() and createCopy() R public interfaces, and improve input validation (Add tests in test-gdal_create.R #748)
• additional tests for class GDALVector with a few minor code improvements (Additional tests for class GDALVector #747)
• class GDALVector: improve error handling in setIgnoredFields()/setSelectedFields() and add several new tests (Class GDALVector: improve error handling in setIgnoredFields() / setSelectedFields() and add several new tests #731)
• make variables constexpr or const in several places

Documentation

• add web article Vector Read Benchmarks
