compareGeom: Compare geometries

Description

Evaluate whether two SpatRasters have the same extent, number of rows and columns, projection, resolution, and origin (or a subset of these comparisons).

Or evaluate whether two SpatVectors have the same geometries, or whether a SpatVector has duplicated geometries.

Usage

# S4 method for SpatRaster,SpatRaster
compareGeom(x, y, ..., lyrs=FALSE, crs=TRUE, warncrs=FALSE, ext=TRUE,
	rowcol=TRUE, res=FALSE, stopOnError=TRUE, messages=FALSE, tolerance=NULL)
# S4 method for SpatVector,SpatVector
compareGeom(x, y, tolerance=0)
# S4 method for SpatVector,missing
compareGeom(x, y, tolerance=0)

Value

logical (SpatRaster) or matrix of logical (SpatVector)

Arguments

x

SpatRaster or SpatVector

y

Same as x. If x is a SpatRaster, y can also be a list of SpatRasters. If x is a SpatVector, y can be missing

...

Additional SpatRasters

lyrs

logical. If TRUE, the number of layers is compared

crs

logical. If TRUE, coordinate reference systems are compared

warncrs

logical. If TRUE, a warning is given if the crs is different (instead of an error)

ext

logical. If TRUE, bounding boxes are compared

rowcol

logical. If TRUE, number of rows and columns of the objects are compared

res

logical. If TRUE, resolutions are compared (redundant when checking extent and rowcol)

stopOnError

logical. If TRUE, code execution stops if raster do not match

messages

logical. If TRUE, warning/error messages are printed even if stopOnError=FALSE

tolerance

numeric. For SpatRaster objects this is the difference in raster extent (expressed as the fraction of the raster resolution) that can be ignored when comparing alignment of rasters. If NULL the value shown by link{terraOptions} is used

Examples

r1 <- rast()
r2 <- rast()
r3 <- rast()
compareGeom(r1, r2, r3)
nrow(r3) <- 10


if (FALSE) {
compareGeom(r1, r3)
}
