compareGeom

Compare geometries of SpatRasters

Description

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

Usage

## S4 method for signature 'SpatRaster,SpatRaster'
compareGeom(x, y, ..., lyrs=FALSE, 
          crs=TRUE, warncrs=FALSE, ext=TRUE, rowcol=TRUE, res=FALSE)

Arguments

`x`	SpatRaster
`y`	SpatRaster
`...`	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)

Examples

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

## Not run: 
compareGeom(r1, r3)

## End(Not run)
