Through the Canterbury Spatial Data Infrastructure (SDI) Programme, LINZ worked with Canterbury local and central government agencies to accelerate the recovery effort by enabling improved sharing and use of location-based information.
Planning for the rebuild of Canterbury required high quality information about where things were – for example infrastructure like electricity and water pipelines, buildings, property boundaries, and land use and ownership.
This location-based information was an essential element of many earthquake-related recovery activities including communications, urban planning, and traffic management.
Agencies involved in the recovery needed to combine and share a lot more location-based information and although substantial progress had been made to increase their capacity, they had been constrained by the lack of a coordinated approach.
Investing in the development and implementation of a spatial data infrastructure in Canterbury meant that information could flow quickly to where it was needed, and tools and services could be built around this information - better serving and supporting the collective recovery effort.
The lessons learned from the Canterbury SDI Programme informed the national SDI, and provided valuable insights and lessons learned to help us understand how to maximise the return on investment on a national scale.
There were 8 projects within the programme:
- GIS Interoperability - Designing and improving software processes to automate data exchange between agencies involved in the recovery using open standards
- Forward works spatial coordination - Developing a spatial viewer for the forward works programme
- 3D enabled cities - Developing ways for people to see what rebuilt Canterbury will look like
- Property data management framework - Connecting land and property information to make rebuilding as easy as possible
- Utilities data access - Improving access to utilities spatial data to enable more open, effective and efficient data sharing with recovery partners
- Canterbury maps - Helping environmental groups and territorial authorities to connect their data to the ECan viewer
- Open data and open API support - Encouraging development of smartphone apps through the use of open data to help recovery of Canterbury
- Geospatial data discovery - Making management of spatial data easy for people to find, share and use
These work-streams explored a broad range of issues and are intended to balance the need for immediate benefits to the recovery and longer-term foundation building for a regional and national SDI.
Through harnessing web technology, facilitating 3D visualisation, allowing process efficiencies and using open standards, the barriers to information exchange in post-earthquake Canterbury were addressed. The programme delivered efficiencies to the public and private sectors, new and innovative tools and services that improve the social and economic state, and enabled the public to be better informed about and more actively participate in the recovery effort.
