地理空间信息应急保障供应链研究

Research on Geospatial Information Emergency Support Supply Chain

在卫星影像制作的DOM和DEM基础上,利用侦查无人机拍摄的影像照片,在DOM底图上计算目标的精确坐标和对DLG数据进行及时更新,满足了应急保障需要。

Based on DOM and DEM which depends on satellite image, this article using pilotless aircraft shoot photo, calculates exactitude coordinate and updates DLG data on the DOM base map, satisfy emergency support demand.
