The Strategic Planning Team wanted Waikirikiri Ki Tua | Future Selwyn to be a dynamic, living strategy supported by interactive maps and graphs in an engaging interface. The Geospatial Team wanted a scalable platform that could cope with each Phase as we expand the site. At phase one, a lot of planning went into how we were going to structure the data and publish web-layers and webmaps to ensure data updates/ expansions were seamless and required very little ongoing work from us. We also considered functionality that was coming in the next phases.

In Phase one of Future Selwyn the geospatial analysis all went into development of the hundreds of datasets that were gathered to build the weblayers used in the interactive maps.
Proximity analysis, raster analysis was used to develop informative datasets which guided the writing of the strategy but are not necessarily mapped in Phase one. These will appear in the Area plans and Monitoring in Phase two.

Our findings have been that using ArcGIS Experience Builder applications resulted in minimal infrastructure change. For Phase one we wanted to keep the platform as much an out-of-the-box solution as possible with minimal customisations. In order to achieve this the planners/marketing and Coms teams have had to make some compromises and the web development, and Geospatial teams have had to come up with some creative work arounds. In the end we have managed to achieve all the functionality that we wanted in Phase One

In the early stages of this project, we reviewed other New Zealand Councils Spatial Strategies. Different councils used a number of different platforms, and all had Pros and Cons. We found looking at other sites invaluable, we believe others will be interested in the challenges and wins we have had configuring our Experience Builder site.

As climate change intensifies, understanding the vulnerability of critical infrastructure becomes essential. Leveraging ArcGIS Dashboards, we developed an interactive solution to visualize and assess how many assets would be affected by different sea level rise scenarios. Being able to quickly see high-level count and kilometers of assets informs decision-making as to which areas are more vulnerable to the impact of sea level rise.

The analysis involved a geospatial intersect between WaterCare’s Water and Wastewater asset data and Sea Level Rise flood scenarios. Creating and populating a numeric column to signify affected or not. This was the backbone of how dashboard indicators were set up to change between sea level scenarios.

With the scale of this project; all Water and Wastewater Assets across Auckland, it was important to design the Dashboard in a way that was efficient while also allowing the user to inspect different areas and scenarios. The data behind the dashboard needed to be in a certain schema to be able to utilize the full capabilities of the dashboard elements, with a range of category selectors, indicators, maps, and lists.

Overall, developing an ArcGIS Online Dashboard was a terrific way to communicate quick-statistic information about potential sea level rise impacts on existing assets.

Traditionally, GIS in architecture is used as a site analysis tool, often transferred to Illustrator. However, this project demonstrates the power of data-driven decision-making in GIS, showing how authoritative datasets can drive conversations about future investments.

Our presentation will focus on how we used the ArcGIS Suitability Modeler, service area analysis, pre-trained deep learning and ArcGIS Urban to help us understand the demographic and statistical characteristics of a client’s customer base to develop a network investment strategy that understands and articulates the spatial relationship between:

· Existing assets

· Locations of highest demand

· Planned growth and infrastructure investment

· Complexity of Centre's

· Levels of public and private transport accessibility

· Centre characteristics

· Site characteristics

Our analysis identified many high-demand areas not previously considered in one government agency's future planning. Based on service demands, we recommended areas for future investment that balanced place, community and organisational needs.
