# USGS CLI

This library comes with a command line interface to expose many common requests, such as authenticating, searching, downloading, and obtaining metadata.

Here’s an example of what can be done using the cli and GitHub Gists.

    usgs search --node EE EO1_HYP_PUB --start-date 20150401 --end-date 20150501 --geojson | gist -f hyperion-20150401-20150501.geojson

## Login

    usgs login [USGS username] [USGS password]

## Logout

    usgs logout [USGS username] [USGS password]

## Search

    usgs search [dataset] --start-date [start date] --end-date [end date] --longitude [lng] --latitude [lat] --node [node]

Suppose you’re interested in declassified satellite imagery. The datasets `CORONA2` or `DECLASSII` can be queried. If you have a GeoJSON file with an AOI, you can pipe the file to `usgs search`.

    cat chile.geojson | usgs search --node EE DECLASSII --start-date 19700101 --end-date 19800101 --geojson | gist -f declassii-chile-1970s.geojson

## Metadata

    usgs metadata [dataset] [entity/scene id 1] [entity/scene id 2] ... [entity/scene id n]

Suppose you want metadata from a couple scenes taken by Hyperion.

    $ usgs metadata --node EE EO1_HYP_PUB EO1H1820422014302110K2_SG1_01 EO1H1830422015093110KF_TR2_01 | jq ""

Unfortunately, this is not all the metadata available for each scene. More metadata is found behind the `metadataUrl`. Using the `extended` flag will send a second request to USGS, and aggregrate the results in the returned JSON.
