Rasterize Spatial Data

Description

This function converts spatial data with x, y coordinates and a value field into a raster using a specified resolution and CRS.

Usage

rasterize_data(x_coords, y_coords, values, cell_size = 5000, crs, fun = mean)

Arguments

x_coords	Numeric vector of x-coordinates (e.g., longitude).
y_coords	Numeric vector of y-coordinates (e.g., latitude).
values	Numeric vector of values associated with each point.
cell_size	Numeric. Grid cell size in meters (default: 5000).
crs	Character, the coordinate reference system in EPSG format (e.g., "EPSG:3857").
fun	Function to aggregate values in cells (default is 'mean').

Value

A 'terra::SpatRaster' object.

Examples

x_coords <- runif(100, -100, 100)
y_coords <- runif(100, -50, 50)
values <- rnorm(100, mean = 10, sd = 5)

rasterize_data(x_coords, y_coords, values,
               cell_size = 5000, crs = "EPSG:3857", fun = mean)
