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 - 3 pixels @ 68% confidence (Sigma 1)Spatial Accuracy Notes - RMSE values of 0.023m in X and 0.072m in Y to existing controlMap Projection - Web Mercator Auxiliary SphereRectification Surface - Rectification processes are via Visionmap LightspeedTile Size / Grid - SW_123000_4567000_1km SW - Refers to the south-west coordinate of the tile (bottom left); 123000 - Coordinate easting of south-west tile corner; 4567000 - Coordinate northing of south-west tile cornerLimitations 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.
