rtoi-class: Region and Time Of Interest (rtoi)

Description

It is a proxy object to store metadata about satellite imagery covering a spatial region over a time period. Images can come from multiple missions/programs and its purpose is to help managing heterogeneous datasets.

Fields

name

a character with the name of the region of interest.

rtoi_path

a character with the path to the rtoi folder.

region

an sf with the region of interest.

records

the satellite records available for your region and time of interest.

db_path

a character with the path to the database.

Details

An rtoi object manages two main folders called database and rtoi. The database is meant to work as a local, generic, and organized archive of raw satellite data retrieved with the download() function. The rtoi folder contains processed information for a particular region and time of interest. When mosaic() is called, the function crops and mosaics the relevant raw images from the database and saves the results in the rtoi folder. This folder also contains a region.rtoi file which saves metadata about the region/time of interest and satellite imagery available.

Examples

if (FALSE) {
data(ex.navarre)
## Create an rtoi with database
# path where the region is stored
rtoi.path <- tempdir()

# path where downloads are stored
db.path <- file.path(tempdir(), "DATABASE")
navarre <- new_rtoi(
  name = "Navarre_rtoi",
  region = ex.navarre,
  rtoi_path = rtoi.path,
  db_path = db.path
)

print(navarre)

## Create an rtoi without database
navarre2 <- new_rtoi(
  name = "Navarre_rtoi2",
  region = ex.navarre,
  rtoi_path = rtoi.path
)

print(navarre2)
}
