收藏资源简介:
该数据集包含厄立特里亚港口的日常活动数据和货物运输估计。每日记录港口呼叫次数、进港和出港货物量(以公吨为单位)。数据集中的每一行代表国家层面的汇总数据。数据最后更新于2026年4月21日,地理范围为厄立特里亚(ERI)。数据集由Electric Sheep Africa整理为适合机器学习的Parquet格式。数据集特性包括:领域为人道主义和发展数据,观察单位为国家层面汇总,总行数为2,664行,列数为31列(24个数值型,6个类别型,0个日期时间型),训练集和测试集分别为2,131行和532行。数据集中的变量包括地理变量(如年份、日期、国家、ISO3代码等)、时间变量(如日期、月份)、标识符/元数据变量(如港口ID、港口名称等)以及其他变量(如各类港口呼叫次数和货物量)。数据集经过清洗和标准化处理,并分为训练集和测试集。数据集的局限性包括数据来源未经ESA独立验证,自动清洗无法纠正原始数据中的误报值、定义不一致或抽样偏差等问题。
This dataset contains daily port activity data and shipment estimates for ports in Eritrea. It includes daily counts of port calls, estimates of incoming and outgoing shipment volumes (in metric tons). Each row in the dataset represents country-level aggregates. The data was last updated on HDX on 2026-04-21, with a geographic scope of Eritrea (ERI). The dataset was curated into an ML-ready Parquet format by Electric Sheep Africa. Dataset characteristics include: domain as humanitarian and development data, unit of observation as country-level aggregates, total rows as 2,664, columns as 31 (24 numeric, 6 categorical, 0 datetime), train split as 2,131 rows, and test split as 532 rows. Variables in the dataset include geographic variables (e.g., year, day, country, iso3), temporal variables (e.g., date, month), identifier/metadata variables (e.g., portid, portname), and other variables (e.g., various port calls and shipment volumes). The dataset has been cleaned and standardized, and split into train and test sets. Limitations of the dataset include that the data originates from PortWatch and has not been independently validated by ESA, and automated cleaning cannot correct for misreported values, definitional inconsistencies, or sampling bias in the original collection.
