crs_engine_rproj: crs2crs transform engine

In paleolimbot/rlibproj: Generic Coordinate Transformation Library ('PROJ') R API

Description

crs2crs transform engine

Usage

crs_engine_rproj(ctx = proj_context(), spatial_test = "intersects")

## S3 method for class 'rlibrpoj_crs2crs_engine'
crs_engine_proj_pipeline(
  engine,
  handleable,
  crs_to,
  crs_from = wk::wk_crs(handleable),
  bbox = wk::wk_bbox(handleable),
  accuracy = NA_real_,
  auth_name = NA_character_,
  allow_ballpark = NA,
  ...
)

## S3 method for class 'rlibrpoj_crs2crs_engine'
crs_engine_proj_pipeline_apply(engine, handleable, pipeline, ...)

## S3 method for class 'rlibrpoj_crs2crs_engine'
crs_engine_get_wk_trans(engine, handleable, crs_to, crs_from, ...)

Arguments

ctx	A proj_context()
spatial_test	Use "none" to skip using extents when selecting the appropriate transform between crs objects.
engine	A transform engine such as crs_engine_null()
handleable	A geometry vector (e.g., wkb(), wkt(), xy(), rct(), or sf::st_sfc()) for which wk_handle() is defined.
crs_to	Source and destination coordinate reference systems
crs_from	Source and destination coordinate reference systems
bbox	The bounding box to use when searching for appropriate transformations.
accuracy	The minimum desired accuracy for the transformation
auth_name	An authority name (e.g., "EPSG" or "OGC")
allow_ballpark	Use FALSE to omit ballpark transformations
...	Unused
pipeline	A character vector representing a PROJ coordinate operation

Value

An engine that can be used with crs_set_engine().
