# Dataset Card for Gaia H3 mapping

<!-- Provide a quick summary of the dataset. -->
The full_h3_map.json contains our global mapping using UberH3.
Most land regions including large islands are covered.
Most urban centers, lakes and large rivers are mapped, with naming and population data.
Cells have a cell type: Base, Urban, River, or Lake

This mapping serves to allow filtering of region type for Gaia models and helps ensure
models only run inference over regions the task is focused on.

### Future Updates

land classification for base cells
high resolution cells over specific climates
Improve coastline coverage
Improve river mapping
Add base cell coverage of smaller islands

### Dataset Sources
Natural Earth Rivers
Natural Earth 50m Populated Places
Natural Earth Lakes
Natural Earth 10m Urban Areas

# Gaia H3映射数据集卡片

<!-- 提供数据集的简要概述 -->
full_h3_map.json文件包含我们基于UberH3构建的全球映射。该映射覆盖了包括大型岛屿在内的大部分陆地区域，涵盖了多数城市中心、湖泊及大型河流，并附带名称与人口数据。每个单元格的类型分为：基础（Base）、城市（Urban）、河流（River）或湖泊（Lake）。

该映射旨在为Gaia模型提供区域类型过滤功能，确保模型仅在任务聚焦的区域上执行推理。

### 未来更新
- 基础单元格的土地分类
- 特定气候区的高分辨率单元格
- 优化海岸线覆盖
- 改进河流映射
- 增加小型岛屿的基础单元格覆盖

### 数据集来源
- Natural Earth Rivers（自然地球河流）
- Natural Earth 50m Populated Places（自然地球50米分辨率聚居地）
- Natural Earth Lakes（自然地球湖泊）
- Natural Earth 10m Urban Areas（自然地球10米分辨率城市区域）
