LAGOS-NE-LOCUS v1.01: A module for LAGOS-NE, a multi-scaled geospatial and temporal database of lake ecological context and water quality for thousands of U.S. Lakes: 1925-2013

This data package, LAGOS-NE-LOCUS v1.01, is 1 of 5 data packages
associated with the LAGOS-NE database-- the LAke multi-scaled
GeOSpatial and temporal database. Three of the data packages each
contain different types of data for 51,101 lakes and reservoirs larger
than 4 ha in 17 lake-rich U.S. states to support research on thousands
of lakes. These three package are: (1) LAGOS-NE-LOCUS v1.01: lake
location and physical characteristics for all lakes. (2) LAGOS-NEGEO
v1.05: ecological context (i.e., the land use, geologic, climatic, and
hydrologic setting of lakes) for all lakes. These geospatial data were
created by processing national-scale and publicly-accessible datasets
to quantify numerous metrics at multiple spatial resolutions. And, (3)
LAGOS-NE-LIMNO v1.087.1: in-situ measurements of lake water quality
from the past three decades for approximately 2,600-12,000 lakes,
depending on the variable. This module was created by harmonizing 87
water quality datasets from federal, state, tribal, and non-profit
agencies, university researchers, and citizen scientists. The other
two data packages contain supporting data for the LAGOS-NE database:
(4) LAGOS-NE-GIS v1.0: the GIS data layers for lakes, wetlands, and
streams, as well as the spatial resolutions that were used to create
the LAGOS-NE-GEO module. (5) LAGOS-NE-RAWDATA: the original 87
datasets of lake water quality prior to processing, the R code that
converts the original data formats into LAGOS-NE data format, and the
log file from this procedure to create LAGOS-NE. This latter data
package supports the reproducibility of LAGOS-NE-LIMNO. The LAGOS-NE-LOCUS v1.01 module includes information on the physical
location and features of all lakes > 4 ha. The information provided
for this population of lakes includes: lake unique identifiers, lake
area, perimeter, latitude and longitude, and the zone IDs that the
lake is located within (e.g., state, county, the hydrologic unit at
each level (4, 8, and 12). Citation for the full documentation of this database: Soranno, P.A., E.G. Bissell, K.S. Cheruvelil, S.T. Christel, S.M.

本数据包LAGOS-NE-LOCUS v1.01是LAGOS-NE数据库（即多尺度湖泊时空数据库，LAke multi-scaled GeOSpatial and temporal database）配套的5个数据包之一。
其中3个核心数据包面向美国17个湖泊富集州内的51101个面积大于4公顷的湖泊与水库，各包含不同类型的数据，用于支撑数千个湖泊的相关研究。这三个核心数据包分别为：
（1）LAGOS-NE-LOCUS v1.01：收录所有湖泊的位置与物理特征信息。
（2）LAGOS-NE-GEO v1.05：收录所有湖泊的生态背景数据，即湖泊的土地利用、地质、气候与水文环境。该空间数据集通过处理国家级公开数据集生成，可在多种空间分辨率下量化多项指标。
（3）LAGOS-NE-LIMNO v1.087.1：收录过去三十年间针对约2600至12000个湖泊的原位湖水水质测量数据，具体数量因监测指标不同而存在差异。该模块通过整合来自联邦、州、部落与非营利机构、高校研究者以及公民科学家的87项水质数据集构建而成。
剩余两个数据包为LAGOS-NE数据库提供辅助支撑数据：
（4）LAGOS-NE-GIS v1.0：包含湖泊、湿地与溪流的GIS数据图层，以及用于生成LAGOS-NE-GEO模块的空间分辨率信息。
（5）LAGOS-NE-RAWDATA：包含处理前的87项原始湖泊水质数据集、将原始数据格式转换为LAGOS-NE标准格式的R代码，以及生成LAGOS-NE过程的日志文件。该数据包用于支撑LAGOS-NE-LIMNO模块研究的可重复性。

LAGOS-NE-LOCUS v1.01模块收录所有面积大于4公顷湖泊的物理位置与特征信息，具体包含：湖泊唯一标识符、湖泊面积、周长、经纬度，以及湖泊所在的分区ID（例如州、县，以及4级、8级、12级水文单元分区ID）。
