extent {gdalcubes} | R Documentation

## Derive the spatiotemporal extent of an image collection

### Description

Derive the spatiotemporal extent of an image collection

### Usage

    extent(x, srs = "EPSG:4326")

### Arguments

`x` | image collection proxy object
`srs` | target spatial reference system

### Value

a list with elements `left`, `right`, `bottom`, `top`, `t0` (start date/time), and `t1` (end date/time)

### Examples

    # create image collection from example Landsat data only
    # if not already done in other examples
    if (!file.exists(file.path(tempdir(), "L8.db"))) {
      L8_files <- list.files(system.file("L8NY18", package = "gdalcubes"),
                             ".TIF", recursive = TRUE, full.names = TRUE)
      create_image_collection(L8_files, "L8_L1TP", file.path(tempdir(), "L8.db"))
    }

    L8.col = image_collection(file.path(tempdir(), "L8.db"))
    extent(L8.col,"EPSG:32618")
    cube_view(extent=extent(L8.col,"EPSG:32618"),
              srs="EPSG:32618", nx = 497, ny=526, dt="P1M")
