Timaru 0.075m Urban Aerial Photos Index Tiles (2022-2023)
Index Tiles ONLY, for actual orthophotos see layer [Timaru 0.075m Urban Aerial Photos (2022-2023)]( http://data.linz.govt.nz/layer/115057 )
Orthophotography within the Canterbury Region captured in the flying season of 2022-2023.
Coverage encompasses locations within the Timaru District including Geraldine, Orari, Winchester, Temuka, Pleasant Point, Timaru city, and Pareora.
Imagery was captured for Environment Canterbury by Landpro Ltd between the 29 December 2022 and 2 March 2023.
Data comprises:
• 1176 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.
Imagery supplied with a 7.5cm pixel resolution (0.075m GSD).

*Data capture *
Imagery for this project was acquired between the 29/12/2022 and 2/03/2023 using both the Leica ADS100 line scanning camera with SH100 sensor head and the RCD30 80 MP camera. The Leica ADS100 line scanning camera was fitted to a Leica PAV100 HP high performance gyro-stabilised mount

*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 requested orthophoto quality specifications. Table 2 provides a summary of the flight parameters during the capture of all areas of interest within the Timaru Urban Towns Schedule

* Environmental capture requirements *
All imagery was captured without the presence of cloud or cloud shadow within the specified areas of interest. All capture flights occurred during times when the sun angle allowed sufficient detail in shadowed areas for features on the ground to be interpreted.
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. Where relevant, all river flow and stage height restrictions were adhered to.
Imagery covering coastal areas was captured within two hours of low tide, and extended out to 100m from the coastline, and 100 m from the perimeter of the harbour.
* Ground control *
Ground control from both historic surveys and surveys carried out by Landpro during the 2022-23 aerial capture season were utilised.
