Add new National Exposure Information System (NEXIS) Building Exposure data

[nf-s]

They want to decommission GeoServer with old data - also the GA MapServer has out-of-date data.

So ideally we pull directly from here:

• National Exposure Information System (NEXIS) Building Exposure - Local Government Area (LGA) - https://ecat.ga.gov.au/geonetwork/srv/eng/catalog.search#/metadata/82219
• National Exposure Information System (NEXIS) Building Exposure - Statistical Area Level 1 (SA1) - https://ecat.ga.gov.au/geonetwork/srv/eng/catalog.search#/metadata/82220

Currently they publish gdb, geojson and XLS - but the file sizes are too large to render client-side.

I will do a test to split of XLS into multiple CSVs - and then I will ask if it is possible for them to publish CSVs and then we can point directly at them.

I was unable to directly connect to the data links in GA’s GeoNetwork as TerriaJS doesn’t natively support XLS or GDB, and the JSON doesn’t follow the GeoJSON standard – the JSON is also on the edge of maximum file size to load directly into TerriaJS.

I ended up manually splitting the XLS into CSV per worksheet and they work well.

I have added the new NEXIS data to our test NationalMap site - https://nationalmap.test.saas.terria.io/#share=s-pxwukHN6S0GSqepijwY5XxzBZ3Z
