Selwyn 0.075m Urban Aerial Photos Index Tiles (2020-2021)
Index Tiles ONLY, for actual orthophotos see layer [Selwyn 0.075m Urban Aerial Photos (2020-2021)]( http://data.linz.govt.nz/layer/10697 3)
Orthophotography within the Canterbury Region captured in the flying season of 2020-2021. Coverage encompasses Lincoln, Rolleston, West Melton and Prebbleton.
Imagery was captured for Environment Canterbury by Landpro Ltd, 13 Pinot Noir Drive, Cromwell 9310, New Zealand.
Data comprises:
• 548 ortho-rectified RGB GeoTIFF images in NZTM projection, tiled into the LINZ Standard 1:500 tile layout
• Tile layout in NZTM projection containing relevant information.
The supplied imagery is in terms of New Zealand Transverse Mercator (NZTM) map projection.
Imagery supplied as 7.5cm pixel resolution (0.075m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is ±0.2m at 90% confidence level in clear flat areas.

**The Camera**
Imagery for this schedule was acquired using the Leica ADS100 line scanning camera with SH100 sensor head. The camera was fitted to a Leica PAV100 HP high performance gyro-stabilised mount.
A copy of the camera calibration certificate can be made available upon request.
**Capture Dates, Time & Sun Angle**
Dates, time and approximate sun angle for the imagery acquisition of each area are identified in the table below.
Area, Date, Time (UTC), Sun Angle
Lincoln, 03/12/2020, 02H15 - 03H00, ± 64°
Rolleston, 22/01/2021, 01H15 - 02H10, ± 66°
West Melton, 16/12/2020, 22H45 - 23H15, ± 54°
Prebbleton, 15/12/2020, 00H38 - 01H45, ± 69
**Flight Planning**
Careful consideration was given during flight planning to geographic location, terrain, topographical characteristics of the area, acquisition efficiency, final output resolution and meeting the various requested orthophoto quality specifications.
**Environmental Specification**
All imagery was captured without the presence of cloud or cloud shadow within the specified areas of interest.
Where affected, all coastal, harbour, and tidal regions were captured during low tide periods, this being defined as the period 2 hours either side of low tide. Imagery covering coastal areas extends from the tide line during low tide periods out to 100 meters. Imagery of harbour areas extends out to 100 meters from the perimeter of the harbour.
Rivers were captured during times of appropriate flow/stage height/rainfall restrictions as specified by the client. These criteria were set to avoid periods of high river flow (flooding), rather than to target abnormally low river flows.
