LAGOS-US GEO v1.0: Data module of lake geospatial ecological context at multiple spatial and temporal scales in the conterminous U.S.

The LAGOS-US GEO data package is one of the core data modules of LAGOS-US, an extensible research-ready platform designed to study the 479,950 lakes and reservoirs larger than or equal to 1 ha in the conterminous US (48 states plus the District of Columbia). The GEO module contains data on the geospatial and temporal ecological setting (e.g., land use, terrain, soils, climate, hydrology, atmospheric deposition, and human influence) quantified at multiple spatial divisions (e.g., equidistant buffers around lakes, watersheds, hydrologic basins, political boundaries, and ecoregions) relevant to the LAGOS-US lake population defined in the LAGOS-US LOCUS module. The database design that supports the LAGOS-US research platform was created based on several important design features: lakes are the fundamental unit of consideration, all lakes in the spatial extent above the minimum size must be represented, and most information is connected to individual lakes. The design is modular, interoperable (the modules can be used with each other), and extensible (future database modules can be developed and used in the LAGOS-US research platform by others). Users are encouraged to use the other two core data modules that are part of the LAGOS-US platform: LOCUS (location, identifiers, and physical characteristics of lakes and their watersheds) and LIMNO (in situ lake physical, chemical, and biological measurements through time) that are each found in their own data packages.

LAGOS-US地理数据包（LAGOS-US GEO data package）是LAGOS-US平台的核心数据模块之一。LAGOS-US是一款可扩展的科研就绪型平台，旨在研究美国本土（含48个州及哥伦比亚特区）内面积≥1公顷的479950个湖泊与水库。
LAGOS-US地理模块（GEO module）存储了多空间分区下量化得到的地理空间与时间尺度生态背景数据，具体包括土地利用、地形、土壤、气候、水文、大气沉降及人类影响程度等指标；相关空间分区涵盖湖泊周边等距缓冲区、流域、水文盆地、行政边界及生态区等类型，所有数据均匹配LAGOS-US LOCUS模块（LAGOS-US LOCUS module）所定义的LAGOS-US湖泊研究种群。
支撑该LAGOS-US科研平台的数据库设计遵循多项核心设计原则：以湖泊为核心研究单元，需完整覆盖空间范围内所有达到最小面积阈值的湖泊，且绝大多数信息均关联至单个湖泊实体。
该设计采用模块化架构，具备互操作性（各模块可协同调用）与可扩展性（后续可由第三方开发新数据库模块并集成至LAGOS-US科研平台）。
平台还提供另外两个核心数据模块供用户使用：LOCUS模块（LAGOS-US LOCUS module，存储湖泊及其流域的位置信息、标识符与物理特征）与LIMNO模块（LIMNO module，存储湖泊原位长期物理、化学及生物监测数据），二者均配备独立的数据数据包。
