Levels 22 - 23 (1:141 - 1:71)West Auckland Aerial Imagery 2024 Color Infrared covers aerials images for the West Auckland region in color infrared. Infrared aerial photography involves capturing images using infrared light, which is outside the visible spectrum. This type of photography is useful for a variety of applications, including environmental monitoring, agriculture, and land management. Infrared imagery can reveal details not visible to the naked eye, such as vegetation health, water stress, and temperature variations, making it valuable for assessing plant vitality, detecting heat sources, identifying areas of moisture, and infrastructure conditions, making it invaluable for environmental monitoring and urban planning.Data Acquisition: The capture was completed between 20th March 2024 and 11th May 2024. Ortho Specification• Ortho-imagery: Three-band• Spectral resolution: Near Infrared, Green, Blue• Pixel resolution: 0.25 m GSD (25 cm)• Spatial accuracy: ±0.4 m @ 95% confidence level in clear flat open spaces (2 sigma) over area of interest• Tile index: Tile index for the project area available in GeoMaps• Aligned to LINZ 1:5000 map sheet layout (2,400 m x 3,600 m)• Total number of tiles supplied: 227 (1:5000 map sheet tiles)• Image format: JPEGNote: Auckland Council can provide R-G-B-NIR imagery for the area in GEOTIFF format as well. Please contact us at gis@aklc.govt.nz to request the four-band imagery. Map Projection All spatial data for this project provided in terms of New Zealand Transverse Mercator 2000 map projection (NZTM2000). The ellipsoidal datum is New Zealand Geodetic Datum 2000 (NZGD2000). The airborne GPS and ground control GPS data was converted from ellipsoidal heights into orthometric heights using the LINZ NZGeoid16 separation model. For this project the orthometric vertical datum is New Zealand Vertical Datum 2016 (NZVD2016).
