TxDOT Seaports

TxDOT's point layer of general seaport locations in the state of Texas. Locations are based off aerial imagery. Texas Gulf Coast ports handled more than 563 million tons of foreign and domestic cargo in 2015 — approximately 22 percent of all U.S. port tonnage. Texas ports generate $368.7 billion in economic activity in the state and $6.9 billion in state and local taxes per year, according to the Texas Ports Association. Seven Texas ports rank in the top 50 of all U.S. ports in terms of annual tonnage, according to the U.S. Army Corps of Engineers, including Houston (2nd), Beaumont (5th), Corpus Christi (6th) and Texas City (15th). The Port of Galveston ranked as the fourth-largest U.S. cruise market based on embarkation, with more than 834,000 passengers in 2015. The use of Texas waterways is forecast to continue to increase — fueled by the expansion of the Panama Canal, the surge in the state's population and more worldwide waterborne trade.

本数据集为德克萨斯州交通运输部（Texas Department of Transportation, TxDOT）制作的得克萨斯州通用海港点图层，点位信息基于航空影像获取。2015年，得克萨斯州墨西哥湾沿岸港口完成内外贸货物吞吐量超5.63亿吨，约占全美港口总吞吐量的22%。据得克萨斯州港口协会（Texas Ports Association）统计，得克萨斯州港口每年为该州创造3687亿美元的经济活动产值，并带来69亿美元的州级与地方税收收入。据美国陆军工程兵团（U.S. Army Corps of Engineers）统计，全美年吞吐量排名前50的港口中有7座位于得克萨斯州，包括休斯顿港（第2位）、博蒙特港（第5位）、科珀斯克里斯蒂港（第6位）以及得克萨斯城港（第15位）。加尔维斯顿港以邮轮登船旅客量计，为全美第四大邮轮母港，2015年旅客吞吐量超83.4万人次。受巴拿马运河扩建、本州人口增长以及全球水上贸易规模扩大的推动，得克萨斯州水路运输使用量预计将持续攀升。
