# Sentinel Hub Downloader

A command-line tool to download GeoTIFF data from Sentinel Hub. It is 
currently focused on BYOC data, so far only tested with Planet PV's of
Soil Water Content and Crop Biomass. But it attempts to work against
any BYOC collection, automatically discovering the bands and metadata.

It has only been tested against smaller files, and works just with the
process api. Making it work with larger areas will likely require batch API
and some iterative approach.

## Features

- Search and download BYOC and Sentinel imagery based on time range and area of interest
- Easy-to-use command line interface
- Support for various spatial filters (bounding box, GeoJSON)
- Configurable output directory 
- Automatically discovers bands and metadata for BYOC collections
- Lets users supply custom evalscripts
- Supports various output data types and nodata values

## Installation

Clone the repository and then install the package:

```bash
pip install sh-downloader
```

## Configuration

Before using the tool, you need to configure your Sentinel Hub credentials:

```
shdown config --client-id YOUR_CLIENT_ID --client-secret YOUR_CLIENT_SECRET
```

This will create a configuration file at `~/.sentinelhub/config.json`.

### Command Help

```
shdown --help

Usage: shdown [OPTIONS] COMMAND [ARGS]...

  Command line tool for downloading data from Sentinel Hub.

Options:
  --debug / --no-debug  Enable debug logging

## Advanced Usage

### Specify bands to download

Download only specific bands from a collection:

```
shdown download --collection sentinel-2-l2a --bbox 14.0 45.0 14.5 45.5 --date 2023-01-30 --bands B04,B03,B02 --output-dir ./images
```

Sample output:

Downloading image for 2023-01-30...
Using specified bands: ['B04', 'B03', 'B02']
Image saved to ./images/sentinel-2-l2a_2023-01-30.tiff

### Set output data type

Specify the output data type for downloaded images:
    
```
shdown download --collection sentinel-2-l2a --bbox 14.0 45.0 14.5 45.5 --date 2023-01-30 --data-type uint16 --output-dir ./images
```

Sample output:

Downloading image for 2023-01-30...
Using data type: UINT16
Image saved to ./images/sentinel-2-l2a_2023-01-30.tiff

## TODO's

- Start issue tracker to put these in
- clean up extra gdal files
- option to provide a template for file naming
- show progress as images are downloading / completing
- make it so 'search' works nicer with byoc (same command, detect uuid and use it as id)
- Try out cloud filtering for PS data, and if it works then check stac metadata for cloud cover dynamically
- Checking of non-byoc collections, and raise error on bad collection names before getting 400 from api not recognizing (like hit collections end point. Perhaps get the list of collections on init? At least the non-byoc ones)
- collection list (and filtering?) to get what collections to ask about.
