layer_spatial.SpatRaster {ggspatial} | R Documentation |
Spatial ggplot2 layer for SpatRaster objects
Description
This is intended for use with RGB(A) rasters (e.g., georeferenced imagery or photos). To work with bands as if they were columns, use df_spatial and geom_raster.
Usage
## S3 method for class 'SpatRaster'
layer_spatial(
data,
mapping = NULL,
interpolate = NULL,
is_annotation = FALSE,
lazy = FALSE,
dpi = 150,
...
)
## S3 method for class 'SpatRaster'
annotation_spatial(data, mapping = NULL, interpolate = NULL, ...)
StatSpatRaster
StatSpatRasterAnnotation
StatSpatRasterDf
GeomSpatRaster
Arguments
data |
A SpatRaster object created with |
mapping |
Currently, only RGB or RGBA rasters are supported. In the future, one may be able to map specific bands to the fill and alpha aesthetics. |
interpolate |
Interpolate resampling for rendered raster image |
is_annotation |
Lets raster exist without modifying scales |
lazy |
Delay projection and resample of raster until the plot is being rendered |
dpi |
if lazy = TRUE, the dpi to which the raster should be resampled |
... |
Passed to other methods |
