## Query

The query API returns only the rows you ask for, as JSON, NDJSON or CSV, from the same typed rows as the files. It needs no key. Rows: https://publicdata.au/api/v1/datasets/sa-river-murray-flood-200gl/rows. Counts and sums: https://publicdata.au/api/v1/datasets/sa-river-murray-flood-200gl/aggregate.

- Rows: https://publicdata.au/api/v1/datasets/sa-river-murray-flood-200gl/rows?limit=5
- Aggregate: https://publicdata.au/api/v1/datasets/sa-river-murray-flood-200gl/aggregate?group=flood_name&metric=count

Each filter is `field=operator.value` in the query string, and every filter must match. A number or date field compares as a number or date, and a text field compares as text. Values are case-sensitive except with `ilike`. Prefix `not.` to negate a filter, as `not.eq.value`. Operators: `eq.value`, `neq.value`, `gt.value`, `gte.value`, `lt.value`, `lte.value`, `like.*text*`, `ilike.*text*`, `in.(a,b,c)`, `is.null`.

- `select`: Fields to return, comma-separated. Every field when absent.
- `order`: `field.asc` or `field.desc`, comma-separated. The publisher's row order when absent.
- `limit`: Rows per page, 1 to 10,000. 100 when absent.
- `offset`: Rows to skip. The `next` URL in each answer sets it for you.
- `group`: On `aggregate`, fields to group by, comma-separated.
- `metric`: On `aggregate`, `count`, `sum.field`, `avg.field`, `min.field` or `max.field`, comma-separated. `count` when absent.
- `format`: `json`, `ndjson` or `csv`. JSON carries the provenance header, and the others carry it in response headers.

Without a version the API answers from the newest loaded version, and that answer changes when the publisher releases again. Put `versions/<date>/` before `rows` or `aggregate` for an answer that never changes. `/api/v1/datasets/<slug>/versions` lists the loaded versions. The API allows 60 requests in 10 seconds from one address. Above that it answers 429 for 10 seconds with a `Retry-After` header, a `RateLimit-Policy` header and a JSON body that gives the limit. Every API answer carries the same `RateLimit-Policy`. A client should wait the `Retry-After` seconds, or read the files, which have no limit.

## Questions

### How do I download River Murray predicted flood extent at 200 GL a day as a CSV file?

Open https://publicdata.au/d/sa-river-murray-flood-200gl/latest/data.csv. It redirects to the newest dated version, which is https://publicdata.au/d/sa-river-murray-flood-200gl/v/2019-01-31/data.csv today. The same path serves Excel, JSON, GeoJSON, Parquet, SQLite, DuckDB, GeoPackage, PMTiles, NDJSON, Arrow. A dated URL never changes, so use it when the file must stay the same.

### Can I open River Murray predicted flood extent at 200 GL a day in Excel?

Yes. https://publicdata.au/d/sa-river-murray-flood-200gl/v/2019-01-31/data.xlsx is a workbook with the 20 rows on a records sheet, the field list on a second sheet and the provenance on a third. The CSV also opens in Excel. https://publicdata.au/d/sa-river-murray-flood-200gl/v/2019-01-31/data.csv.gz is the CSV at about a tenth of the size.

### How often is River Murray predicted flood extent at 200 GL a day updated?

Environment and Water no longer updates it. This site checks the portal every week and adds a dated version when the file changes.

### Can I use River Murray predicted flood extent at 200 GL a day commercially?

Yes. CC BY 4.0 allows commercial use, redistribution and derived works as long as the attribution is kept. The attribution string is in this page's side column and inside every file.

### Is this the official source for River Murray predicted flood extent at 200 GL a day?

No. The publisher is Department for Environment and Water, and its page is https://data.sa.gov.au/data/dataset/flood-mapping-of-the-river-murray-200gl. This site republishes the publisher's file without changing its content. The original sits beside every version as source.zip with its SHA-256, so the two can be compared.

### What coordinate system does River Murray predicted flood extent at 200 GL a day use?

Shapes in GDA2020 (EPSG:7844), from the GDA2020 layer the publisher ships beside a GDA94 copy. The GeoJSON file uses GDA2020 as well, which differs from the WGS84 GeoJSON expects by well under a metre.

### What is in each row?

One polygon of land the model predicts is under water when the River Murray flows at 200 gigalitres (200,000 megalitres) a day at the South Australian border. Every row carries the same flood name, and the shapes are in the GeoParquet, GeoJSON, GeoPackage and PMTiles files.

### Is this a record of a real flood?

No. It is a modelled scenario from a study the Department ran for flood preparedness and risk management. The extent of the 2022 to 2023 flood, which was mapped from imagery, is a separate dataset in this collection.

## What this site did to the data

Cells were typed, headers were renamed to snake_case and the encoding was made UTF-8. Rows were left alone. Nothing is derived. The publisher's file is beside every version as `source.zip`.
