2014 True Color Aerial Mosaic, Ottawa National Wildlife Refuge, Crane Creek Estuary

The true color aerial imagery contained in this mosaic was collected on July 17, 2014 with an Applanix 439 Digital Sensor System. The mission was flown at ~3,000 ft. above ground level resulting in a ground sample distance of 0.15 meters (6")/pixel. This true color mosaic was intended to complement the color infrared image classification by providing an additional image format to consider. A flight plan was not used and this resulted in incomplete coverage. The area of interest is the Crane Creek estuary in the Ottawa NWR and the mosaic is for the purpose of habitat monitoring.

本镶嵌图包含的真彩色航空影像采集于2014年7月17日，搭载的传感器为Applanix 439型数字传感器系统（Applanix 439 Digital Sensor System）。本次飞行任务的飞行高度约为地面以上3000英尺，最终获取的地面采样距离（ground sample distance）为0.15米（6英寸）/像素。本真彩色镶嵌图旨在通过提供额外可供参考的影像格式，辅助彩色红外（color infrared）影像分类任务。本次任务未预先制定飞行规划方案，导致影像覆盖存在不完整的情况。本次研究的关注区域为奥塔瓦国家野生动物保护区（Ottawa NWR）内的克兰克里克河口，该镶嵌图的制作用途为生境监测。
