It is used to visualise the landscape, detect change, and provide spatial context to other data.
Survey resolution (ground sample distance) varies depending on the purpose of the individual procurements.
- Rural aerial imagery is typically 20-30cm resolution with regional scale coverage.
- Urban aerial imagery is typically 5-20cm resolution with city scale coverage.
- Project satellite imagery is typically 50-100cm resolution focused on targeted areas.
- Annual satellite imagery mosaics are based on 10m imagery sourced from the European Space Agency’s Sentinel-2A and Sentinel-2B satellites - these mosaics are published to provide 100% imagery coverage of Aotearoa New Zealand.
