mt_to_terra: Convert tidy MODISTools data to terra SpatRaster

In MODISTools: Interface to the 'MODIS Land Products Subsets' Web Services

Convert tidy MODISTools data to terra SpatRaster

Description

Convert tidy MODISTools data to a terra SpatRaster for easy spatial processing and plotting.

Usage

mt_to_terra(df, reproject = FALSE, method = "bilinear")

Arguments

df	a valid MODISTools data frame with a single band (filter for a particular band using the dplyr filter() function or base subset()
reproject	reproject output to lat / long (default = FALSE)
method	character. Method used for estimating the new cell values of a SpatRaster. One of: near: nearest neighbor. This method is fast, and it can be the preferred method if the cell values represent classes. It is not a good choice for continuous values. This is used by default if the first layer of x is categorical. bilinear: bilinear interpolation. This is the default if the first layer of x is numeric (not categorical). cubic: cubic interpolation. cubicspline: cubic spline interpolation.

Value

A terra SpatRaster populated with the tidy dataframe values
