Get the bounding box of the data

Obtain a vector of limits (either on lat/long for time series or in projection coordinates in the case of cubes)

Usage

sits_bbox(data, ..., crs = "EPSG:4326", as_crs = NULL)

# S3 method for class 'sits'
sits_bbox(data, ..., crs = "EPSG:4326", as_crs = NULL)

# S3 method for class 'raster_cube'
sits_bbox(data, ..., as_crs = NULL)

# S3 method for class 'tbl_df'
sits_bbox(data, ..., crs = "EPSG:4326", as_crs = NULL)

# Default S3 method
sits_bbox(data, ..., crs = "EPSG:4326", as_crs = NULL)

Arguments

data

samples (class "sits") or cube.

...

parameters for specific types

crs

CRS of the time series.

as_crs

CRS to project the resulting bbox.

Value

A bbox.

Note

Time series in sits are associated with lat/long values in WGS84, while each data cubes is associated to a cartographic projection. To obtain the bounding box of a data cube in a different projection than the original, use the as_crs parameter.

Examples

if (sits_run_examples()) {
    # get the bbox of a set of samples
    sits_bbox(samples_modis_ndvi)
    # get the bbox of a cube in WGS84
    data_dir <- system.file("extdata/raster/mod13q1", package = "sits")
    cube <- sits_cube(
        source = "BDC",
        collection = "MOD13Q1-6.1",
        data_dir = data_dir
    )
    sits_bbox(cube, as_crs = "EPSG:4326")
