Description: Project ReportSafety: No safety Incidents were reported during the project.Acquisition: Aerial photography used for this project was captured using Vexcel's digital UCE andUCLp camera:5 January 2017 and 6 February 2017.Ground Support: Existing control and LINZ benchmarks were used for aerial triangulation.Data Presentation: The data provided on this volume has been supplied in accordance with aspecification agreed with Hamilton City Council.Project Contacts:Hamilton City GIS Solution Architect: Joga Bhatia (Ph. 07 838 6532)Aerial Surveys National Account Manager: Jenny Bakker (Ph. 09 415 3101)Data AcquisitionThe aerial photography for this project was captured within the 2016/17 flying season (September2016 – April 2017) on the following dates:5 January 2017 and 6 February 2017.A map showing the area of interest is included in Appendix A.CameraAll urban area photography was captured using Vexcel's digital UCE camera and flown at:0.10 m GSD: 6551 ft (1996 m) flying heightCamera Lens: 100 mmAll CBD and hospital area photography was captured using Vexcel's digital UCLp camera and flown at:0.10 m GSD: 3829 ft (1167 m) flying heightCamera Lens: 70 mmGround ControlA combination of existing control and LINZ benchmarks were used for aerial triangulation for thisproject.Data ProcessingThe collection of building footprint data for this project was undertaken by our mapping partnerCyient Ltd with final QA being undertaken in-house by Aerial Surveys staff.Map ProjectionAll spatial data for this project provided in terms of New Zealand Transverse Mercator 2000 mapprojection (NZTM2000). The datum is New Zealand Geodetic Datum 2000 (NZGD2000). The heightdatum is orthometric Moturiki 1953 (sea level).Building FootprintsBuilding footprints collected from the stereo models for all buildings greater than 10 m2. Captured as3D closed polygons and attributed with a simple level attribute including height data. Building heightdata was digitised at the elevation of each roof eave. Pergolas, decks and other such structuresattached to buildings were not captured. Upon completion of the data capture, checks were carriedout to ensure the topology was clean and seamless.Mapping area: 168.65 sq km283,267 features captured
