## 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/qld-flood-extent-2011-january/rows. Counts and sums: https://publicdata.au/api/v1/datasets/qld-flood-extent-2011-january/aggregate.

- Rows: https://publicdata.au/api/v1/datasets/qld-flood-extent-2011-january/rows?feature_type=eq.Floodline&limit=5
- Aggregate: https://publicdata.au/api/v1/datasets/qld-flood-extent-2011-january/aggregate?group=location&metric=count&feature_type=eq.Floodline

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 Queensland towns flood extent as a CSV file?

Open https://publicdata.au/d/qld-flood-extent-2011-january/latest/data.csv. It redirects to the newest dated version, which is https://publicdata.au/d/qld-flood-extent-2011-january/v/2015-06-11/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 Queensland towns flood extent in Excel?

Yes. https://publicdata.au/d/qld-flood-extent-2011-january/v/2015-06-11/data.xlsx is a workbook with the 892 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/qld-flood-extent-2011-january/v/2015-06-11/data.csv.gz is the CSV at about a tenth of the size.

### How often is Queensland towns flood extent updated?

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

### Can I use Queensland towns flood extent 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 Queensland towns flood extent?

No. The publisher is Department of Natural Resources and Mines, Manufacturing and Regional and Rural Development, and its page is https://www.data.qld.gov.au/dataset/flood-extent-series. This site republishes the publisher's file without changing its content. The original sits beside every version as source.geojson with its SHA-256, so the two can be compared.

### What coordinate system does Queensland towns flood extent use?

The map service projects the polygons to WGS84 (EPSG:4326) on request. They are moved to GDA2020 for publication. 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 mapped flood extent, with the feature type, the location name, the source the outline was drawn from and the reliability dates the department records for the shape and its attributes.

### Is this the peak of the flood?

Not always. The department describes the polygons as the approximate inundation when the source imagery or survey was captured, and recommends them for use at about 1:5,000 to 1:10,000.

### Can I use it to tell whether a property will flood?

No. It shows one past flood. Councils publish flood planning maps for present risk.

## 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.geojson`.
