Welcome to the interactive river flow data explorer. This is a proof of concept for the New Zealand Environmental Integrated Data Infrastructure Project. For more information, see the 'About this Project' tab.
The tool shows river monitoring sites on a map, coloured according to how the current flow rate compares with the average flow rate at that site. Click on a site to load further details, including a time series chart of flow at that site.
The 'Data' tab contains a filterable, sortable, searchable list of all sites, along with key facts and context about each site.
The 'Chart' tab allows you to view historical data for a site. This chart also has the ability to show multiple sites on the same axes, to support comparisons between sites.
Any text on this site that appears blue is a hyperlink. Clicking these links will take you to that thing's page on the PublishMyData platform. This is a more technical view of the data, but does provide more information abut the thing, and can also provide a platform for more advanced queries in the SPARQL endpoint.

This tool has been created using R-Shiny. All the code is available on Github, please feel free to fork it here: https://github.com/Swirrl/nz_shiny_river_app .

Plain English Summary
The Ministry, NRS and Regional Sector are developing a data tool to enable people to query real time, linked river level and flow data provided by participating regional councils. The tool will enable people to search and compare data on river levels and flows in the same way the Trivago website enables people to search and compare the price of hotel rooms. The main reason for developing the tool is so people can get river data within a few minutes. At the moment people have to email their data requests to data providers and wait around a month for an answer. The data tool is possible because regional councils and the Ministry for the Environment have standardised the way they measure, collect and exchange regional environmental data in New Zealand. The Ministry is currently testing the idea to see if it works and aims to show the concept from this website from July. If the regional government sector and the natural resource sector think the concept is useful, the next step will be to develop a larger project to provide access to more data through the tool.
The Environmental Integrated Data Infrastructure (architectural proof of concept scoping) project received funding from the Better Public Services Seed Fund, administered by the Treasury. The purpose of this project is to demonstrate the exchange of data between MfE and the other Natural Resource Sector agencies (DIA, DOC, LINZ, MBIE, MPI, STATS) and data supplier organisations such as regional councils. The proof of concept will use established technologies, including web technologies, location intelligence, and linked data, to connect different data holdings into a single, seamless, virtual data service. The data layer will be able to be accessed from current systems, and the proof of concept is complying to data and web standards as much as possible and will also provide an online tool to enable browsing, querying, and accessing the data. The data will continue to be stored and managed by the contributing agencies. In the first instance, the POC will be demonstrating the brokering of real-time water-related data services (flow) from regional councils, using common vocabularies, and building on the NEMS (National Environmental Monitoring Standards) data exchange protocol (Environmental Observation Data Protocol) developed between NIWA, Landcare, GNS, Horizons and Genesis Energy.
