About Planet Catcher
An independent creator brand focused on Earth science. We tell the story of a changing planet with data and discover the warmth of the world through maps — from the melting Antarctic ice sheet to the veins of urban traffic, from the hydraulic wisdom of ancient civilizations to simulations of future sea levels. Our mission is to make professional geography intuitive, engaging, and within reach.
Science Communication
Nearly 200 original articles on the blog, covering physical geography, climate and environment, human geography, and GIS technology — professional phenomena explained in plain language.
Interactive Tools
Self-built online geography tools — coordinate lookup, terrain analysis, GeoJSON conversion and more — making geographic data processing accessible beyond specialists.
Visualization Works
Interactive visualization projects such as the sea-level simulation lab, 3D data dashboards, and urban road-network mapping, turning complex geographic data into perceptible, interactive experiences.
Content is also published on Bilibili, YouTube, Xiaohongshu, Weibo, and the WeChat Official Account (星球小捕手)
Our Mission
Earth science should not live only in papers and laboratories. We believe everyone who is curious about the world deserves to understand the planet we live on in an intuitive and engaging way. Whether it is grasping how rising seas affect coastal cities or exploring the planning logic behind urban road networks, we use technology to bring geography out of the papers and into everyday life.
Our team is one person plus a group of AI Agents — what we call an OPC (One Person Company). With technical leverage and creative passion, we keep producing high-quality geography content and interactive tools.
