Functions for the LAScatalog processing engine not meant to be called directly by users
Description
Functions for the LAScatalog processing engine not meant to be called directly by users. They are exported for debugging and to simplify export of internal functions when processing in parallel
Usage
engine_apply(
.CHUNKS,
.FUN,
.PROCESSOPT,
.OUTPUTOPT,
.GLOBALS = NULL,
.AUTOREAD = FALSE,
.AUTOCROP = FALSE,
...
)
engine_chunks(ctg, realignment = FALSE, plot = opt_progress(ctg))
engine_crop(x, bbox)
engine_merge(ctg, any_list, ...)
engine_write(x, path, drivers)
Arguments
.CHUNKS |
list. list of LAScluster |
.FUN |
function. function that respects a template (see catalog_apply) |
.PROCESSOPT |
list. Processing option |
.OUTPUTOPT |
list. Output option |
.GLOBALS |
list. Force export of some object in workers |
.AUTOREAD |
bool. Enable autoread |
.AUTOCROP |
bool. Enable autocrop |
... |
parameters of .FUN |
ctg |
LAScatalog |
realignment |

x |
LAS, Raster, stars, SpatRaster,sf, sfc, Spatial |
bbox |
bbox |
any_list |
list of LAS, Raster, stars, SpatRaster, sf, sfc, Spatial, data.frame |
