## Landsat8 Metadata API
**Important:** This tool is retired and no longer maintianed. Please use [sat-api](https://github.com/sat-utils/sat-api).
A version of **sat-api** with Landsat metadata is accessible [here](https://api.developmentseed.org/satellites/landsat).
This is an API for NASA/USGS Landsat-8 images. Landsat-api enables you to make geospatial, date and text queries on Landsat-8 metadata.
The metadata is released in csv format by USGS on a daily basis. You can download the raw metadata from [here](http://landsat.usgs.gov/metadata_service/bulk_metadata_files/LANDSAT_8.csv).
Download and install the lastest version of elastic search zip from [ES website](http://www.elasticsearch.org/download/)
Landsat-api powers a number of projects including [Libra](https://libra.developmentseed.org) and AstroDigtal's [Imagery Browser](https://fetch.astrodigital.com).
#### Dependencies
- [MongoDb](http://docs.mongodb.org/v2.6/installation/) [2.6 or higher]
or
- [ElastiSearch](https://www.elastic.co/downloads/elasticsearch) [1.6 or higher]
#### Installation
Install packages
$: npm install
Set environment variables on your system or add an `.env` file to the root directory of the app:
- `DB_TYPE=mongo` choices are `mongo` or `es`
- `ES_HOST=example.com:9200` if you are using ElasticSearch
- `MONGODB_URL=mongodb://user:pass@example.com:11111/db_name` if you use MongoDb
- `AREA_LIMIT=500000` The area limit in (sq. km) for use in geo-spatial queries.
- `REDIS_USE=true` Whether to active the caching. Default is false.
- `REDIS_HOST=127.0.0.1` default is `127.0.0.1`
- `REDIS_PASSWORD=redispassword` Redis db password. Default is null.
- `REDIS_DATABASE=myredisdb` Name of the redis db. Default is null.
- `REDIS_PORT=6379` Redis port. Default is 6379.
- `LANDSAT_PAYLOAD_LIMIT` Limit of payload size for POST in bytes. Default is 2048000.
#### Run
To run the api:
$ node index.js
To run the database updater
$ node updater.js
*Note:* `updater.js` works with MongoDb. If you plan to update an ElasticSearch installation replace `updater.js` with examples found [here](https://github.com/developmentseed/landsat-meta-updater/tree/develop/examples).
#### Test
$ npm test
