shapefile_surface: Generate a spatial surface plot based on interpolated values

Description

This function creates a surface plot from an interpolated spatial model, with options to customize plot appearance, grid resolution, and color palette.

Usage

shapefile_surface(
  model,
  curve = TRUE,
  nx = 300,
  ny = 300,
  xlab = "Longitude (UTM)",
  ylab = "Latitude (UTM)",
  col = custom_palette(c("darkred", "yellow", "forestgreen"), n = 100),
  ...
)

Value

A surface plot showing spatially interpolated data.

Arguments

model

An interpolated spatial object (e.g., from shapefile_interpolate()) containing the data for plotting.

curve

Logical; if TRUE, a contour plot is generated (type = "C"), otherwise an image plot (type = "I"). Default is TRUE.

nx

Integer; the number of grid cells in the x-direction. Default is 300.

ny

Integer; the number of grid cells in the y-direction. Default is 300.

xlab

Character; label for the x-axis. Default is "Longitude (UTM)".

ylab

Character; label for the y-axis. Default is "Latitude (UTM)".

col

A color palette function for the surface plot. Default is a custom palette from dark red to yellow to forest green.
