[![STAC Browser Badge](https://img.shields.io/badge/Open_in_STAC_Browser-%2309B3AD?style=flat&label=New%20Zealand%20Elevation&labelColor=%23144E63)](https://radiantearth.github.io/stac-browser/#/external/nz-elevation.s3-ap-southeast-2.amazonaws.com/catalog.json?.language=en)

[![AWS Badge](https://img.shields.io/badge/Open_in_Registry_of_Open_Data_on_AWS-%23FF9900.svg?logo=amazon-web-services&logoColor=white&labelColor=%23232F3E)](https://registry.opendata.aws/nz-elevation/)

Toitū Te Whenua makes New Zealand's most up-to-date publicly owned elevation data freely available to use under an open licence. You can access this through the [LINZ Data Service](https://data.linz.govt.nz/data/category/elevation/), [LINZ Basemaps](https://basemaps.linz.govt.nz/@-41.8899962,174.0492437,z5?i=elevation) or the [Registry of Open Data on AWS](https://registry.opendata.aws/nz-elevation/).

## Quickstart

Browse the archive with [STAC Browser](https://radiantearth.github.io/stac-browser/#/external/nz-elevation.s3-ap-southeast-2.amazonaws.com/catalog.json?.language=en) or access the catalog directly [https://nz-elevation.s3-ap-southeast-2.amazonaws.com/catalog.json](https://nz-elevation.s3-ap-southeast-2.amazonaws.com/catalog.json)

## Background

This repository contains STAC Collection metadata for each elevation dataset, as well as some guidance documentation:

- [Naming](docs/naming.md) covers the `s3://nz-elevation` bucket naming structure

- [Usage](docs/usage.md) shows how TIFFs can be interacted with from S3 using GDAL, QGIS, etc

- [Elevation Compression](docs/tiff-compression/README.md) provides commentary and analysis on the compression options we explored.

## AWS Access

Toitū Te Whenua owns and maintains a public bucket which is sponsored and shared via the [Registry of Open Data on AWS](https://registry.opendata.aws/nz-elevation/) `s3://nz-elevation` in `ap-southeast-2`.

Using the [AWS CLI](https://aws.amazon.com/cli/) anyone can access all of the imagery specified in this repository.

```

aws s3 ls --no-sign-request s3://nz-elevation/

```
