rsat_mosaic: Mosaic the tiles intersecting the region of interest

In rsat: Dealing with Multiplatform Satellite Images

Mosaic the tiles intersecting the region of interest

Description

Satellite measurements are divided into indivisible units called tiles. The mosaic function binds and crops the tiles to generate a single image of the region of interest for each date.

Usage

rsat_mosaic(x, ...)

## S4 method for signature 'rtoi'
rsat_mosaic(x, ...)

## S4 method for signature 'records'
rsat_mosaic(
  x,
  out_path,
  db_path,
  bfilter,
  warp = "extent",
  region,
  overwrite = FALSE,
  ...
)

Arguments

x	an rtoi object.
...	additional arguments.
out_path	path to save the mosaicked images. By default, the path is defined by x.
db_path	path to the database. By default, the path is defined by x.
bfilter	a vector of bands to. If not supplied, all are used.
warp	character. If equal to "extent", it also crops the images around the rtoi. Use "" otherwise.
region	an sf object. Region for cropping the images around. By default, the path is defined by x.
overwrite	logical argument. If TRUE, overwrites the existing images with the same name.

Value

nothing. Mosaics the downloaded images and stored them on the hard disk

) #'
# Landsat-5
rsat_search(
  region = navarre,
  product = "LANDSAT_TM_C1",
  dates = as.Date("1988-08-01") + seq(1, 35)
)
