sits_get_probs: Get values from probability maps

In e-sensing/sits: Satellite Image Time Series Analysis for Earth Observation Data Cubes

Get values from probability maps

Description

Given a set of lat/long locations and a probability cube, retrieve the prob values of each point.

Usage

sits_get_probs(cube, samples, window_size = NULL)

## S3 method for class 'csv'
sits_get_probs(cube, samples, window_size = NULL)

## S3 method for class 'shp'
sits_get_probs(cube, samples, window_size = NULL)

## S3 method for class 'sf'
sits_get_probs(cube, samples, window_size = NULL)

## S3 method for class 'sits'
sits_get_probs(cube, samples, window_size = NULL)

## S3 method for class 'data.frame'
sits_get_probs(cube, samples, window_size = NULL)

## Default S3 method:
sits_get_probs(cube, samples, window_size = NULL)

Arguments

cube	Probability data cube from where data is to be retrieved. (class "class_cube").
samples	Location of the samples to be retrieved. Either a tibble of class "sits", an "sf" object, the name of a shapefile or csv file, or a data.frame with columns "longitude" and "latitude"
window_size	Size of window around pixel (optional)

Value

A tibble of with columns <longitude, latitude, values> in case no windows are requested and <longitude, latitude, neighbors> in case windows are requested

Note

There are four ways of specifying data to be retrieved using the samples parameter: (a) CSV file: a CSV file with columns longitude, latitude; (b) SHP file: a shapefile in POINT geometry; (c) sits object: A sits tibble; (d) sf object: An link[sf]{sf} object with POINT or geometry; (e) data.frame: A data.frame with longitude and latitude.
