Why is it difficult to map the entire world?

Mapping the entire world is challenging due to several factors, including the vastness and complexity of the Earth's geography, which encompasses diverse terrains, climates, and ecosystems. Additionally, the constantly changing nature of the environment, such as urban development, natural disasters, and climate change, complicates the accuracy of maps. Technological limitations and the need for extensive resources for data collection and analysis also hinder comprehensive mapping efforts. Finally, political boundaries and issues of sovereignty can restrict access to certain regions, further complicating the mapping process.
