Terrestrial Oil Spill Detection and Environmental Impact Monitoring using Multi-Source Earth Observation Data

过去几年，在加拿大艾伯塔省等地区，人们对陆上或陆上石油和废水泄漏的担忧大幅增加。例如，2012年春季，一条管道泄漏了950万升工业废水，这是北美近代史上最大的泄漏事件，发生在阿尔伯塔省北部扎马市东北约20公里处[1]。许多重要的生态系统，包括河流、湖泊、湿地和植被地区，都受到此类泄漏的威胁。随着管道的建立和通过铁路(加拿大铁路协会)等其他方式运输石油的增加，以及发生石油泄漏的可能性增加，迫切需要制定方法，以便及早发现泄漏、提取和划定受影响区域，并监测补救过程的有效性。遥感是一种快速、成本效益高的技术，可用于溢油检测和环境影响监测。

Concerns about terrestrial or land-based oil and waste water spills have increased considerably in the past several years in the areas such as Alberta, Canada. For example, in spring 2012, a pipeline leaked 9.5 million liters of industrial waste water, the North America’s biggest spill in recent history, about 20 kilometres of Northeast of Zama City in Northern Alberta [1]. Many ecologically important ecosystems including rivers, lakes, wetlands and vegetation areas are threatened by such spills. With increasing establishment of pipelines and shipment of oil by other means such as rail (Railway Association of Canada) and higher possibility of oil spills, there is an immediate need to develop methods for early detection of spill, extraction and delineation of impacted areas, and monitoring the effectiveness of remediation process. Remote sensing is a rapid and cost effective technology that can be utilized for oil spill detection and environmental impact monitoring.
