Tools for Local Climate Zone and Urban Heat Island Analysis in R

The LCZ4r package offers a suite of functions designed to analyze and visualize Local Climate Zones and Urban Heat Islands in R.

Package Overview

The LCZ4r is a comprehensive toolkit, including the following functions:

• lcz_get_map() Download your LCZ map from global dataset
• lcz_get_map_euro() Download your LCZ map from European dataset
• lcz_get_map_usa() Download your LCZ map from Continental United States dataset
• lcz_plot_map() Visualize the LCZ map
• lcz_cal_area() Calculate LCZ areas
• lcz_get_parameters() Retrieve LCZ parameters
• lcz_plot_parameters() Visualize LCZ parameter map
• lcz_ts() Analyze LCZ Time Series
• lcz_anomaly() Calculate LCZ Thermal Anomalies
• lcz_anomaly_map() Map LCZ Thermal Anomaly
• lcz_interp_map() Map LCZ Interpolation
• lcz_plot_interp() Visualize LCZ Interpolation
• lcz_uhi_intensity() Assess LCZ for Urban Heat Island Intensity

🗃️ Instalation

To Install to the LCZ4r use the development version on GitHub.

Function types and tutorials

These functions are categorized into two main types: general functions and local functions. The general functions are tailored for circumstances where specific LCZ data is not readily available. In contrast, the local functions are designed to operate with more extensive data inputs, such as urban meteorological network readings, including air temperature.

We highly recommend that users explore the following tutorials to gain a deeper understanding of the capabilities and applications of the LCZ4r package:
