Kite Aerial Photography NIMS grid Imnavait, Alaska 2014

Aerial photographs of the Networked Info-Mechanical System (NIMS) grid in Imnavait, Alaska were taken using a rig and kite system. As part of the NIMS grid, white boards were nailed into the tundra to act as Ground Control Points (GCPs). The purpose of these boards was to facilitate the visibility of the grid from the aerial photographs, as well as to facilitate georeferencing using ArcMap Geographic Information System (GIS). Most of the pictures taken are high resolution although only a few are lacking good quality. The photographs are arranged according to flight date.

本数据集涵盖美国阿拉斯加州伊姆纳韦特（Imnavait）地区网络化信息机械系统（Networked Info-Mechanical System, NIMS）网格的航空影像，所有影像均通过航测搭载装置与风筝航拍系统拍摄完成。作为该NIMS网格的组成部分，研究人员将白板钉设于苔原之上，作为地面控制点（Ground Control Points, GCPs）。此类白板的核心作用包括两点：一是提升该网格在航空影像中的可视辨识度，二是便于借助ArcMap地理信息系统（Geographic Information System, GIS）完成地理配准。本次采集的影像绝大多数为高分辨率成果，仅少数存在画质不佳的问题，所有航空影像均按照航摄日期进行排序整理。
