Airborne video has demonstrated promise as a rapid, low-cost means of acquiring imagery for a variety of ecological applications: fish and wildlife habitat, plant communities, phytomass determination, crop damage, weed infestations. Image acquisition can be timed to coincide with an event of interest (e.g., a flood, an algae bloom) at a spatial scale suitable for detecting objects as small as individual organisms (e.g., trees, geese). The benefits of airborne video could be greatly enhanced, however, by combining frame-grabbed video images into a comprehensive geo-referenced database suitable for use in a Geographic Information System (GIS) where the information could be integrated with other spatial databases (e.g., population density, land ownership) and manipulated using the multitude of spatial analysis tools inherent to GISs. Therefore, the goal of this award is to develop a prototype airborne video database acquisition system capable of: 1) gathering all the information needed to georeference a video image at the moment of acquisition, 2) displaying in real time the spatial extent and location of images acquired, and 3) selecting images for analysis and mosaicing them into a comprehensive GIS coverage.

机载视频表明，有望成为一种快速，低成本的手段，用于为各种生态应用获取图像：鱼类和野生动植物栖息地，植物群落，植物量确定，作物损害，杂草侵扰。 可以将图像采集定时与感兴趣的事件（例如，洪水，藻类开花）相吻合，适合于检测像单个生物（例如树木，鹅）一样小的物体。 但是，通过将框架的视频图像结合到适合在地理信息系统（GIS）中使用的全面地理参考数据库中，可以极大地提高空气中的视频的好处，在该数据库中，可以将信息与其他空间数据库集成（例如，人口密度，土地所有权）并使用空间分析工具进行操纵。 因此，该奖项的目的是开发一个原型机载视频数据库采集系统：1）收集在获取时收集视频图像所需的所有信息，2）实时显示图像的空间范围和图像的空间范围和位置，以及3）选择图像以进行分析并将其镶嵌在全面的GIS覆盖范围中。
