Historical DOP 1995-2004
收藏资源简介:
WMS for the presentation of historical, digital orthophotos (DOPs) from 1995 to 2004 in grayscale (PAN). DOPs are equal to the plane, georeferenced aerial images. The projection of the aerial images is carried out via a digital terrain model (DGM) of the Earth’s surface. The layer “DOP 2004-2000” represents digital orthophotos from 2000 to 2004. In overlap areas, the newer DOPs superimposed the older ones. The layer “DOP 2000-2004” represents digital orthophotos from 2000 to 2004. In overlap areas, the older DOPs overlay the newer ones.
本Web地图服务(Web Map Service,WMS)用于展示1995年至2004年间的灰度全色(Panchromatic,PAN)数字正射影像(Digital Orthophotos)。数字正射影像等同于经过平面地理配准的航空影像。航空影像的投影计算通过地表数字地形模型(Digital Terrain Model,DGM)实现。图层"DOP 2004-2000"对应2000年至2004年的数字正射影像,在影像重叠区域中,较新的数字正射影像将覆盖较旧的影像。图层"DOP 2000-2004"同样对应2000年至2004年的数字正射影像,在影像重叠区域中,较旧的数字正射影像将覆盖较新的影像。
