Environmental Change Analysis Geoportal (ECAG)

最近取得的进展以及网上制图工具和多谱段卫星图像的可用性为环境监测提供了前所未有的机会。这些机会是将大量公开提供的卫星图像、先进的处理技术以及因特网门户提供的广泛提供和可访问性结合起来的结果。然而，获取、分析和可视化遥感数据通常需要昂贵的成像软件、功能强大的台式计算机和专业技术知识。因此，按需可视化和监控环境现象、影响和变化的能力仅限于少数用户。AKS地球科学公司与美国地质勘探局合作项目的目标是：和塞尔柯克学院地理空间研究中心是设计一个基于网络的地理门户网站，提供免费访问公共可用的图像和互动的能力，应用AKS分析的图像感兴趣的地区。示例应用涉及量化土地表面属性随时间的变化，并将包括采矿复垦工作，石油泄漏清理效率和监测植被演替。将复杂的遥感软件的功能带给普通用户，通过网络访问，将使用户能够以独特的方式探索数据，从而对地表状况有全新的了解。该项目的未来目标是创建一个与公共门户网站一起运行的商业版门户网站，但能够进一步获取最新的高分辨率图像，并能够根据需要对图像进行更复杂的分析。

Recent advancements and availability of web-based mapping tools and multispectral satellite imagery provide unprecedented opportunities for environmental monitoring. These opportunities are the result of combining a wealth of publicly available satellite imagery, advanced processing techniques, and the wide availability and accessibility provided by an internet portal. However, obtaining, analyzing, and visualizing remotely sensed data generally requires expensive imaging software, powerful desktop computers, and specialized technical expertise. Thus, the ability to visualize and monitor, on-demand, environmental phenomenon, impacts, and change is limited to a few users. The goal of a collaborative project between AKS Geoscience Inc. and the Selkirk College Geospatial Research Center is to design a web-based geoportal that provides free access to publicly available imagery and the ability to interactively apply AKS analysis on the imagery for an area of interest. Example applications involve quantifying land surface attribute change over time, and would include mining reclamation efforts, oil spill clean-up efficacy, and monitoring vegetation succession. Bringing the functionality of sophisticated remote sensing software to the general user, accessible via the web will allow the user to explore data in unique ways which brings a whole new understanding of surface conditions. A future goal of this project is to create a commercial version of the portal that operates in conjunction with the public portal, but enables additional access to the latest high resolution imagery and ability to apply, on-demand, more complex analysis of the imagery.
