A Comprehensive Guide to Map Construction in China

Introduction

China is on the verge of a significant transformation in its mapping capabilities, with plans to create a comprehensive 3D map of the country by 2035. This initiative aims to utilize real-scene 3D technology to depict geological conditions, urban landscapes, and specific buildings, thereby supporting social and economic development. As urbanization accelerates, understanding the dynamics of urban construction sites (UCS) becomes crucial. This guide explores the technical features, types, and implications of map construction in China, drawing insights from various domains, including www.Chinadaily.com.cn, global.Chinadaily.com.cn, and www.sciencedirect.com.
