Orthophotography within the Tasman Region captured in January and March 2022. Coverage encompasses Tasman's northern rural area in the Tasman and Nelson Regions of the South Island.
Imagery was captured for Tasman District Council by Aerial Surveys Ltd, Unit A1, 8 Saturn Place, Albany 0632, New Zealand.
Data comprises: • 346 ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:5000 tile layout • Tile layout in NZTM projection containing relevant information.
The supplied imagery is in terms of New Zealand Transverse Mercator (NZTM) map projection. Please refer to the tile index layer for specific details, naming conventions, etc.
Imagery supplied as 30cm pixel resolution (0.30m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is ±0.5m at 95% confidence level in clear flat areas.
Index tiles for this dataset are available as layer [Tasman 0.3m Rural Aerial Photos Index Tiles (2022)](http://data.linz.govt.nz/layer/109476)
Data Acquisition The aerial photography for this project was captured within the 2021/22 flying season (September 2021 – April 2022).
Camera and Flying Height All photography was captured using Vexcel's digital UCE camera fitted with the 100 mm lens and flown at an altitude of approximately 18,932 ft (5,770 m) with the lowest ground GSD set at 0.30m.
Capture Dates The aerial imagery was captured on the following dates: 30 January 2022, 14-15 March 2022.
Sun Angle Imagery captured with a minimum sun angle of +30 degrees. The sun angle of the imagery used for the orthorectification ranged from 35.6 to 54.4 degrees.
Flight Planning The flight survey number for this project is SN14225 The flight plan is named ‘Tasman Rural 21-22 30cm UCE V2’ and comprises 31 runs, 1,042 frames. All imagery captured in stereo: forward overlap 60%, min 54%; side overlap 35%, min 15%.
Environmental Specification Imagery captured with no cloud or cloud shadow within the area of interest. Tidal areas captured +/-1.5 hours either side of low tide.
Ground Control A combination of existing control and LINZ benchmarks were used for aerial triangulation for this project.
