# Sentinel-2 MGRS Tile Search API
Simple Ruby on Rails based API to query Sentinel-2 data by MGRS on AWS. Data imported daily from AWS with
the [sentinel2_aws gem](https://github.com/beaorn/sentinel2_aws).
Live version is deployed at https://sentinel2.satgateway.com
Tile Preview Viewer implementing this API: [sentinel2-search-viewer](https://github.com/beaorn/sentinel2-search-viewer)
## Setup
Prerequisites: Ruby, Bundler, Ruby on Rails, PostgreSQL, PostGIS, and Redis
Clone project, copy database and secrets example configs and set them up.
```bash
cp config/database.example.yml config/database.yml
cp config/secrets.example.yml config/secrets.yml
```
Install gems, setup database, run migrations, and seed database
```bash
bundle install
createdb sentinel2-search-api_development
psql sentinel2-search-api_development
```
```sql
CREATE SCHEMA postgis;
CREATE EXTENSION postgis WITH SCHEMA postgis;
\q
```
```bash
rails db:migrate
rails import_mgrs_grids
```
## Running Project
Start server
```bash
bundle exec rails server
```
Start sidekiq (requires redis server to be running)
```bash
bundle exec sidekiq
```
### Import product and tile data by date
```ruby
SentinelWorker.perform_async("2017-12-14")
```
### Import product and tile data by date range
```ruby
(Date.new(2017, 12, 1)..Date.new(2017, 12, 31)).each do |date|
date_str = date.strftime("%Y-%m-%d")
SentinelWorker.perform_async(date_str)
end
```
### Scheduled Daily Imports
Add scheduled calls to SentinelWorker in `config/schedule.rb`.
## Tile API Examples
- mgrs parameter format is utm_zone + latitude_band + grid_square
- start_date and end_date parameter formats are YYYY-MM-DD
