Abstract: DTM supplied as a single file aligned to LINZ 1:1,000 sheet layout as gridded 4m DEM in Arc ASCII Grid format. DTM Accuracy: ±0.2 m @ 95% confidence level in clear open areas (2 sigma)
Statement: The DTMOrtho creation was collected by one of 2 methods: a) From updating existing 2006 Lidar, or.... b) from 0.125 m GSD stereo imagery using photogrammetric techniques, largely automated pixel matching and auto-correlation process that creates mass points (known as Match-t) of the terrain surface with further manual editing to remove points on water bodies. Further checking for image distortion is undertaken and issues rectified within the DTM. Bridges are dealt with manually. A Triangulated Irregular Network (TIN) was then created and used for the ortho rectification process.

Tauranga-Taupo Delta Area 2017 - Orthophotos

 
File Identifier: 536078CF-B5E1-166A-E055-000000000001 Parent Identifier: 526D658D-FEE8-5F24-E055-000000000001
Hierarchy Level: feature Hierarchy Level Name:feature of Aerial Photography - Tongariro and Tauranga-Taupo Delta Areas 2017
Abstract: Orthophotos supplied in RGB uncompressed Geotiff with TFW and ECW with ERS. All spatial data for this project provided in terms of New Zealand Transverse Mercator GD2000 map projection (NZTM2000). The datum is New Zealand Geodetic Datum 2000 (NZGD2000). The height datum is orthometric Moturiki 1953 (sea level).
Statement: The Aerial photography was captured as part of the WRAPS 2017 Waikato LASS contract within the 2016/17 flying season (September 2016 – April 2017) on the following dates: 21-22 November 2016. Aerial photography was captured using Vexcel's digital UCE camera and flown at: 0.125 m GSD: 9108 ft (2776 m) flying height.
Other Information: Image Processing and Aerial Triangulation: All imagery has gone through QA checks ensuring there is no cloud cover and cloud shadow. During aerial acquisition the aircraft on-board GPS navigation data and ground base station data collected and post processed. Imagery processed to level 3 and checked for colour correctness/radiometry and even tonal balance across each project area. The aerial triangulation brings together the GPS data and imagery using a two part process which stitches the imagery together using tie point matching for the relative orientation phase and observing ground control points for the absolute orientation phase. LINZ control, 8th order horizontal and 4th order vertical and other existing control from Aerial Surveys control data base were used to strengthen the block adjustment or as independent checks on position during final QA of the ortho imagery. A final report is generated to check RMSE values are within specification. RGB Ortho Rectification Process: Ortho rectification is the process of removing (from the image) the effects of camera tip/tilt and displacement caused by terrain relief. During this process each frame is 'draped' over the terrain model and the photograph then becomes 'scaled' and 'levelled' in terms of true ground coordinates. The generation of seamlines between frames follow natural physical features such as ridges, valleys, roads and rivers. The seamlines are used for the final ortho mosaic that stitches the imagery together using feather mosaicking techniques. The ortho imagery is then extracted aligned to LINZ 1:1000 sheet tile layout.

Hierarchy Level: feature Hierarchy Level Name:feature of Aerial Photography - Tongariro and Tauranga-Taupo Delta Areas 2017
Abstract: Orthophotos supplied in RGB uncompressed Geotiff with TFW and ECW with ERS. All spatial data for this project provided in terms of New Zealand Transverse Mercator GD2000 map projection (NZTM2000). The datum is New Zealand Geodetic Datum 2000 (NZGD2000). The height datum is orthometric Moturiki 1953 (sea level).
Statement: The Aerial photography was captured as part of the WRAPS 2017 Waikato LASS contract within the 2016/17 flying season (September 2016 – April 2017) on the following dates: 21-22 November 2016. Aerial photography was captured using Vexcel's digital UCE camera and flown at: 0.125 m GSD: 9108 ft (2776 m) flying height.
Other Information: Image Processing and Aerial Triangulation: All imagery has gone through QA checks ensuring there is no cloud cover and cloud shadow. During aerial acquisition the aircraft on-board GPS navigation data and ground base station data collected and post processed. Imagery processed to level 3 and checked for colour correctness/radiometry and even tonal balance across each project area. The aerial triangulation brings together the GPS data and imagery using a two part process which stitches the imagery together using tie point matching for the relative orientation phase and observing ground control points for the absolute orientation phase. LINZ control, 8th order horizontal and 4th order vertical and other existing control from Aerial Surveys control data base were used to strengthen the block adjustment or as independent checks on position during final QA of the ortho imagery. A final report is generated to check RMSE values are within specification. RGB Ortho Rectification Process: Ortho rectification is the process of removing (from the image) the effects of camera tip/tilt and displacement caused by terrain relief. During this process each frame is 'draped' over the terrain model and the photograph then becomes 'scaled' and 'levelled' in terms of true ground coordinates. The generation of seamlines between frames follow natural physical features such as ridges, valleys, roads and rivers. The seamlines are used for the final ortho mosaic that stitches the imagery together using feather mosaicking techniques. The ortho imagery is then extracted aligned to LINZ 1:1000 sheet tile layout.
