Orthophoto Flight Dates Chart (resolution 25 cm) 2018

Coverage chart by flight date of the Ortophoto 2018, made with the digital frame camera DMCIII of Leica. Represented by a shapefile file of polygons corresponding to Navarra. Each polygon represents the same flight date in the making of the orthophoto mosaic, so we can know the flight date of each of the areas of the orthophoto. At the edge of the polygon that defines each zone and which is close to another flight date, the exact date cannot be secured as the final delimitation could have changed.徕卡(Leica) DMCIII 数字画幅相机采集制作的2018年正射影像(Ortophoto)按飞行日期划分的覆盖范围图表。该数据集以对应纳瓦拉(Navarra)的多边形形状文件(shapefile)进行呈现。每个多边形对应正射影像镶嵌作业中的同一飞行拍摄日期，据此可明确正射影像各区域的飞行拍摄时间。在界定各区域的多边形边缘且毗邻其他飞行日期的区域内，由于最终边界可能发生调整，无法确保获取准确的拍摄日期。
