Gisborne 0.4m Rural Aerial Photos Index Tiles (2012-2013)
Index Tiles ONLY, for actual orthophotos see layer [Gisborne 0.4m Rural Aerial Photos (2012 - 2013)]( http://data.linz.govt.nz/layer/17 22).
Orthophotography for the Gisborne District Council taken during 2012 and 2013. Coverage encompassed the entire Gisborne District Council area.
Imagery was captured for the ‘Boplass ltd and Gisborne District Council’ by NZ Aerial Mapping Ltd, 208 Warren Street, PO Box 6, Hastings 4156, New Zealand.
The supplied imagery is in terms of New Zealand Transverse Mercator (NZTM) map projection. The products are tiled into NZTopo50 1:5,000 tiles. Please refer to the supplied tile layout shape file for specific details, naming conventions, etc.
Imagery supplied as 40cm pixel resolution (0.4m GSD), 3-band (RGB) uncompressed GeoTIFF. The final spatial accuracy is +/-2.0m (@ 90% confidence).

Data Acquisition:
The Aerial Photography over this area was acquired using the UCXp and
UXC camera systems on the following dates:

21 Jan 2012
29 Jan 2012
26 March 2012

The data was collected flying 5646 and 6670 metres above lowest ground.
These settings were selected to create a dataset with 0.4mGSD.
NZAM used a number of LINZ geodetic marks, Geosystems iBASE and
NZAM geodetic marks for the collection of GPS basestation data during the
aerial data acquisition. Detail of these will be provided in the final project
report.
Independent of the aerial survey work Opus International Consultants
Limited surveyed a series of ground control points for use in the Aerial
Triangulation of the raw images, and for QA of the final orthophotos.
Data Processing:
The sensor positioning and orientation (POS) was determined using the
acquired GPS/IMU datasets and Applanix POSPac software. This work was
all undertaken in NZGD2000 geodetic reference system using the data
collected at the LINZ geodetic reference marks for the differential processing.
The POS data was combined with the ground control in Aerial Triangulation
(AT) to geo-reference the raw photography in NZTM map projection. This
process was undertaken using Microsoft’s UltraMap AT and Leica’s ORIMA
software.
AT data, raw images and processed LiDAR DTM data were supplied to the
orthophoto production team for Orthophoto Generation. All subsequent data
processing steps were undertaken using Inpho’s OrthoVista, PCI and Socet
Set processing software.
The final orthophotos were checked for completeness of project coverage,
general appearance and accuracy.
The positional accuracy of the data has been checked by overlaying the Opus
field surveyed features on the dataset. The data was found to fit well in
position. The project specified positional accuracy of +/-2.0m (90%
confidence) has been met.
