sits (version 1.12.0)

sits_coverage: Provides information about one coverage used to retrieve data

Description

Defines a coverage to retrieve data. As default, it uses the metadata about a chosen coverage stored in an yml configuration file.

• service: Name of time series service that provides the coverage (e.g., "WTSS", "SATVEG", "RASTER").

• name: Name of the coverage (must be unique).

• bands: Vector of bands.

• scale_factor: Vector of scale factors.

• missing_values: Vector of missing values.

• minimum_values: Vector of minimum values.

• maximum_values: Vector of maximum values.

• timeline: The timelines of the coverage (more than one if data has been classified).

• xmin: Spatial extent (xmin).

• ymin: Spatial extent (ymin).

• xmax: Spatial extent (xmax).

• ymax: Spatial extent (ymin).

• xres: Spatial resolution (x dimension).

• yres: Spatial resolution (y dimension).

• crs: Projection CRS.

• files: Files associated with the coverage (in case of raster data).

Examples

# NOT RUN {
# Example 1. Retrieve information about a WTSS coverage
coverage.tb <- sits_coverage(service = "WTSS-INPE", name = "MOD13Q1")

# Example 2. Create a raster coverage with metadata
# read a raster file and put it into a vector
files <- c(system.file("extdata/raster/mod13q1/sinop-crop-ndvi.tif", package = "sits"))

# create a raster coverage file based on the information about the files
raster.tb <- sits_coverage(service = "RASTER", name  = "Sinop-crop",
             timeline = timeline_modis_392, bands = "ndvi", files = files)
