# Description

The **usgsxplore** Python package provides an interface to the [M2M API](https://m2m.cr.usgs.gov/) to search and donwloads scenes.

This package is highly inspired of [landsatxplore](https://github.com/yannforget/landsatxplore) but it support more dataset and add functionalities.

# Quick start

Searching for Landsat scenes that contains the location (5.7074, 45.1611) acquired between 2010-2020.

```bash
usgsxplore search landsat_tm_c2_l1 --location 5.7074 45.1611 --interval-date 2010-01-01 2020-01-01
```

Search for Hexagon KH-9 scenes. Save the result into a geopackage

```bash
usgsxplore search declassii --filter "camera=H" --output results.gpkg
```

Downloading the 10 first images from landsat_tm_c2_l1
```bash
usgsxplore search landsat_tm_c2_l1 --limit 10 --output results.txt
usgsxplore download results.txt
```

# Installation

The package can be installed using pip.

```bash
pip install usgsxplore
```

# Usage

**usgsxplore** can be used both through its command-line interface and as a python module.

## Command-line interface

```bash
usgsxplore --help
```

```
Usage: usgsxplore [OPTIONS] COMMAND [ARGS]...

  Command line interface of the usgsxplore. Documentation :
  https://github.com/adehecq/usgs_explorer

Options:
  --help  Show this message and exit.

Commands:
  download  Download scenes with their entity ids provided in the textfile.
  search    Search scenes in a dataset with filters.
```

### Credentials

Credentials for the Earth Explorer portal can be obtained [here](https://ers.cr.usgs.gov/register/).

`--username` and `--token` or `--password` can be provided as command-line options or as environment variables:

``` shell
export USGSXPLORE_USERNAME=<your_username>
export USGSXPLORE_TOKEN=<your_token>
export USGSXPLORE_PASSWORD=<your_password>
```

### Searching

```bash
usgsxplore search --help
```

```
Usage: usgsxplore search [OPTIONS] DATASET

  Search scenes in a dataset with filters.

Options:
  -u, --username TEXT          EarthExplorer username.  [required]
  -p, --password TEXT          EarthExplorer password.
  -t, --token TEXT             EarthExplorer token.
  -o, --output PATH            Output file : (txt, json, gpkg, shp, geojson)
  -l, --location FLOAT...      Point of interest (longitude, latitude).
  -b, --bbox FLOAT...          Bounding box (xmin, ymin, xmax, ymax).
  -c, --clouds INTEGER         Max. cloud cover (1-100).
  -i, --interval-date TEXT...  Date interval (start, end), (YYYY-MM-DD, YYYY-
                               MM-DD).
  -f, --filter TEXT            String representation of metadata filter
  -m, --limit INTEGER          Max. results returned. Return all by default
  --pbar                       Display a progress bar
  --help                       Show this message and exit.
```

If the `--output` is not provided, the command will print entity ids of scenes found. Else if the `--output` is provided it will save results in the file. There is 5 availables format for the results:
- **text file (.txt)** : Each line is an entity id and the first line contain the dataset ex: `#dataset=landsat_tm_c2_l1`. This file is often use to download the scenes.
- **json file (.json)** : json file containing the results of the search.
- **vector data (.gpkg, .shp, .geojson)** : save the results in a vector data file, usefull to visualise the results.

The search command work with multiple scene-search so there is no limit of results, but you can fixe one with `--limit`.

If you provide a wrong dataset, a list of 50 datasets with high string similarity will be print.

The `--filter` work like this "`field1=value1 & field2=value2 | field3=value3`". For the field you can put either the filter id, the filter label, or the sql filter. For the value you can put either value or value label. Exemples:
```bash
# select scenes of satelites Hexagon KH-9
# all of those 4 command will give the same results
usgsxplore search declassii --filter "camera=L"
usgsxplore search declassii --filter "Camera Type=L"
usgsxplore search declassii --filter "5e839ff8cfa94807=L"
usgsxplore search declassii --filter "camera=KH-9 Lower Resolution Mapping Camera"

# select scenes of satelites Hexagon KH-9 if their are downloadable
usgsxplore search declassii --filter "camera=L & DOWNLOAD_AVAILABLE=Y"
```

### Downloading

```bash
usgsxplore download --help
```
```
Usage: usgsxplore download [OPTIONS] TEXTFILE

  Download scenes with their entity ids provided in the textfile. The dataset
  can also be provide in the first line of the textfile : #dataset=declassii

Options:
  -u, --username TEXT       EarthExplorer username.
  -p, --password TEXT       EarthExplorer password.
  -t, --token TEXT          EarthExplorer token.
  -d, --dataset TEXT        Dataset
  -o, --output-dir PATH     Output directory
  -b, --pbar INTEGER RANGE  Type of progression displaying (0,1,2)  [0<=x<=2]
  -m, --max-thread INTEGER  Max thread number (default: 5)
  --overwrite               Overwrite existing files
  --help                    Show this message and exit.
```
This command download scenes from their entity ids in the `TEXTFILE` and save the results in `--output-dir`. It can display different type of progression depends on `--pbar` value:
- **0** : display nothing.
- **1** : display one progress bar for all scenes downloading.
- **2** : display a progress bar for each scenes downloading, with state information.
