compareGeom function

Compare geometries

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.

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

## S4 method for signature 'SpatVector,SpatVector'
compareGeom(x, y, tolerance=0)

## S4 method for signature 'SpatVector,missing'
compareGeom(x, y, tolerance=0)

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

Returns

logical (SpatRaster) or matrix of logical (SpatVector)

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