Environmental Change Analysis Geoportal (ECAG)

最近基于网络的绘图工具和多光谱卫星图像的进步和可获得性为环境监测提供了前所未有的机会。这些机会是大量可公开获取的卫星图像、先进的处理技术以及互联网门户网站提供的广泛可获得性和可访问性相结合的结果。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的技术专业知识。因此，可视化和监控、按需、环境现象、影响和更改的能力仅限于少数用户。AKS Geoscience Inc.和塞尔柯克学院地理空间研究中心合作项目的目标是设计一个基于网络的地理门户网站，提供免费访问公开可用的图像并能够在感兴趣区域的图像上交互应用AKS分析的能力。应用的例子包括量化地表属性随时间的变化，并将包括采矿复垦努力，石油泄漏清理效率，以及监测植被演替。将复杂的遥感软件的功能带给普通用户，通过网络访问，将允许用户以独特的方式探索数据，这将带来对地表条件的全新理解。该项目未来的目标是创建一个商业版本的门户网站，与公共门户网站一起运作，但使人们能够更多地获取最新的高分辨率图像，并能够按需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.
