Service Description: Imagery Capture
Sensor - A3 35
Focal Length - 300 mm
Imagery Type - RGB
Acquisition Date(s) - 2020-11-05
Flying Height (above MSL) - 8300 feet
Number of Images - 66
Capture Methodology - Primary Runs - 4, Secondary/Tie Runs - 0
Forward / Side Overlap (%) - 56 / 65.5

Orthosmosaic
A digital orthophoto is a raster image of remotely sensed data in which displacement in the image due to sensor orientation and terrain relief have been corrected (orthorectification). 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 cm
Spatial Accuracy - 3 pixels @ 68% confidence (Sigma 1)
Spatial Accuracy Notes - No existing control held over the site
Map Projection - Web Mercator Auxiliary Sphere
Rectification Surface - Rectification processes are via Visionmap Lightspeed
Tile 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 corner

Limitations of Data
This 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.
