catalog_subset function

Subset a LAScatalog

Subset a LAScatalog interactively using the mouse. Subset a LAScatalog with a spatial object to keep only the tiles of interest. It can be used to select tiles of interest that encompass spatial objects.

catalog_intersect(
  ctg,
  y,
  ...,
  subset = c("subset", "flag_unprocessed", "flag_processed")
)

catalog_select(
  ctg,
  mapview = TRUE,
  subset = c("subset", "flag_unprocessed", "flag_processed")
)

Arguments

• ctg: A LAScatalog
• y: bbox, sf, sfc, Extent, Raster*, Spatial* objects
• ...: ignored
• subset: character. By default it subsets the collection It is also possible to flag the files to maintain the collection as a whole but process only a subset of its content. flag_unprocessed flags the files that will not be processed. flag_processed flags the files that will be processed.
• mapview: logical. If FALSE, use R base plot instead of mapview (no pan, no zoom, see also plot )

Returns

A LAScatalog object
