prepare.vector.data: Prepare vector data for further reflectance data sampling

In olehprylutskyi/spectralR: Obtain and Visualize Spectral Reflectance Data for Earth Surface Polygons

Prepare vector data for further reflectance data sampling

Description

The function takes shapefile with polygons of different surface classes (habitats, crops, vegetation, etc.), and retrieves ready-for-sampling sf object.

Usage

prepare.vector.data(shapefile_name, label_field)

Arguments

shapefile_name	shapefile name (should be within working directory, using absolute paths were not tested)
label_field	name of the field which contains class labels

Value

sf object with label (characters) and class (integer) variables, as well as geometry of each polygon, ready to further processing by rgee.

Examples

# Load example data
load(system.file("testdata/reflectance_test_data.RData", package = "spectralR"))

# Prepare vector data
sf_df <- prepare.vector.data(
  shapefile_name = system.file("extdata/test_shapefile.shp", package = "spectralR"),
  label_field = "veget_type")

head(sf_df)
