Orthophotos combine the image characteristics of a photograph with the geometric qualities of a map and can be used as a backdrop layer in conjunction with other spatial information.Spatial Resolution - 6 cmSpatial Accuracy - 18cmMap Projection - Web Mercator Auxiliary SphereRectification Surface - Client supplied DTM data. Accuracy unknownTile Size / Grid - 1km x 1kmLimitations of DataThis dataset contains imagery which has been aero-triangulated, spatially adjusted and rectified using a digital ground surface model. The stated spatial accuracy of this product is relevant for features present at ground level only. Elevated structures (roof-tops, tree canopies, etc) will be affected by relief displacement and cannot be reliably measured from this product. Spatial accuracy is reduced in areas of dense vegetation.
