Sejak diperkenalkan pada tahun 2012, Zona Iklim Lokal (LCZ) muncul sebagai standar baru untuk mengkarakterisasi lanskap perkotaan, yang memberikan pendekatan klasifikasi holistik yang memperhitungkan penutup lahan skala mikro dan properti fisik terkait.
Peta global Zona Iklim Lokal ini, dengan ukuran piksel 100 m dan representatif untuk tahun nominal 2018, berasal dari beberapa set data pengamatan bumi dan label kelas LCZ pakar. LCZ_Filter adalah
band yang direkomendasikan untuk sebagian besar pengguna. Rentang klasifikasi lainnya, LCZ, hanya disediakan karena digunakan untuk menghitung rentang LCZ_Probability.
Skema LCZ melengkapi skema penggunaan lahan / penutup lahan lainnya dengan berfokus pada jenis lanskap perkotaan dan pedesaan, yang dapat dijelaskan oleh salah satu dari 17 kelas dalam skema LCZ. Dari 17 kelas LCZ, 10 di antaranya mencerminkan lingkungan 'buatan', dan setiap jenis LCZ dikaitkan dengan deskripsi numerik generik dari parameter kanopi perkotaan utama yang penting untuk memodelkan respons atmosfer terhadap urbanisasi. Selain itu, karena LCZ awalnya dirancang sebagai kerangka kerja baru untuk studi pulau panas perkotaan, LCZ juga berisi serangkaian terbatas (7) kelas tutupan lahan 'alami' yang dapat digunakan sebagai area 'kontrol' atau 'referensi alami'.
Karena tujuh kelas alami dalam skema LCZ ini tidak dapat mencakup heterogenitas ekosistem alami yang ada di dunia, kami menyarankan pengguna - jika diperlukan - untuk menggabungkan kelas LCZ yang dibuat dengan produk tutupan lahan lainnya yang menyediakan berbagai kelas tutupan lahan alami yang lebih luas.

Lapisan probabilitas yang mengidentifikasi seberapa sering LCZ modal dipilih per piksel (misalnya, probabilitas 60% berarti kelas LCZ modal dipetakan 30 kali dari 50 model LCZ). Ini adalah probabilitas berbasis piksel yang berasal dari lapisan LCZ

LCZ_Filter is the\nrecommended band for most users. The other classification band, LCZ, is\nonly provided as it is used to calculate the LCZ_Probability band.\n\nThe LCZ scheme complements other land use / land cover schemes by\nits focus on urban and rural landscape types, which can be described by\nany of the 17 classes in the LCZ scheme. Out of the 17 LCZ classes, 10\nreflect the 'built' environment, and each LCZ type is associated with\ngeneric numerical descriptions of key urban canopy parameters critical to\nmodel atmospheric responses to urbanisation. In addition, since LCZs were\noriginally designed as a new framework for urban heat island studies, they\nalso contain a limited set (7) of 'natural' land-cover classes that can be\nused as 'control' or 'natural reference' areas.\n\nAs these seven natural classes in the LCZ scheme can not capture the\nheterogeneity of the world's existing natural ecosystems, we advise\nusers - if required - to combine the built LCZ classes with any other\nland-cover product that provides a wider range of natural land-cover\nclasses.\n\nSee also:\n\n- [LCZ Typology](https://doi.org/10.1175/BAMS-D-11-00019.1)\n\n- [Global map of LCZs - paper](https://doi.org/10.5194/essd-14-3835-2022)\n\n- [Global map of LCZs - dataset](https://doi.org/10.5281/zenodo.6364593)\n\n- [LCZ Gaussian filtering](https://doi.org/10.1038/s41597-020-00605-z)\n\n### Bands\n\n\n**Pixel Size**\n\n100 meters\n\n**Bands**\n\n| Name | Units | Pixel Size | Description |\n|-------------------|-------|------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| `LCZ` | | meters | The raw, pixel-based global LCZ map with LCZ classes |\n| `LCZ_Filter` | | meters | The recommended global LCZ map with LCZ classes.
