# ![eoreader_logo](https://eoreader.readthedocs.io/en/latest/_static/favicon.png) EOReader

**EOReader** is a **multi-satellite reader** allowing you to open
[optical](https://eoreader.readthedocs.io/en/latest/optical.html)
and [SAR](https://eoreader.readthedocs.io/en/latest/sar.html) data.

||**Optical** | **SAR**|
|--- | --- | ---|
|**Sensors**|+ Sentinel-2 & Theia<br>+ Sentinel-3 OLCI & SLSTR<br>+ Landsats 1 - 8<br>+ PlanetScope<br>+ Pleiades<br>+ SPOT 6-7| + Sentinel-1<br>+ COSMO-Skymed<br>+ TerraSAR-X<br>+ RADARSAT-2|

It also implements additional **sensor-agnostic** features:

- [`load`](https://eoreader.readthedocs.io/en/latest/api/eoreader.products.product.Product.html#eoreader.products.product.Product.load): Load many band types:
    - satellite bands ([optical](https://eoreader.readthedocs.io/en/latest/optical.html#satellite-bands) or [SAR](https://eoreader.readthedocs.io/en/latest/sar.html#sar-bands))
    - [index](https://eoreader.readthedocs.io/en/latest/optical.html#available-index)
    - [cloud bands](https://eoreader.readthedocs.io/en/latest/optical.html#cloud-bands)
    - [DEM bands](https://eoreader.readthedocs.io/en/latest/optical.html#dem-bands)
- [`stack`](https://eoreader.readthedocs.io/en/latest/api/eoreader.products.product.Product.html#eoreader.products.product.Product.stack): Stack all these type of bands

EOReader works with [`xarrays.DataArray`](http://xarray.pydata.org/en/stable/generated/xarray.DataArray.html#xarray.DataArray)
and [`geopandas.GeoDataFrames`](https://geopandas.org/docs/user_guide/data_structures.html#geodataframe)


## Python Quickstart

The main features of EOReader are gathered hereunder.
For optical data:

```python
>>> from eoreader.reader import Reader
>>> from eoreader.bands.alias import *

>>> # Landsat-5 MSS path, can be found in CI/DATA
>>> l5_path = "LM05_L1TP_200029_19841014_20200902_02_T2.tar"

>>> # Create the reader object and open satellite data
>>> eoreader = Reader()
>>> l5_prod = eoreader.open(l5_path)  # The Reader will recognize the satellite type from its structure

>>> # Get the footprint of the product (usable data) and its extent (envelope of the tile)
>>> footprint = l5_prod.footprint()
>>> extent = l5_prod.extent()

>>> # Specify a DEM to load DEM bands
>>> import os
>>> from eoreader.env_vars import DEM_PATH
>>> os.environ[DEM_PATH] = "my_dem.tif"

>>> # Load some bands and index: they will all share the same metadata
>>> bands = l5_prod.load([NDVI, GREEN, HILLSHADE, CLOUDS])

>>> # Create a stack with some other bands
>>> stack = l5_prod.stack([NDWI, RED, SLOPE])

>>> # Read Metadata
>>> mtd, namespace = l5_prod.read_mtd()
```

For SAR data:

```python
>>> from eoreader.reader import Reader
>>> from eoreader.bands.alias import *

>>> # Sentinel-1 GRD path, not provided in package
>>> s1_path = "S1B_EW_GRDM_1SDH_20200422T080459_20200422T080559_021254_028559_784D.zip"

>>> # Create the reader object and open satellite data
>>> eoreader = Reader()
>>> s1_prod = eoreader.open(s1_path)  # The Reader will recognize the satellite type from its name

>>> # Get the footprint of the product (usable data) and its extent (envelope of the tile)
>>> footprint = s1_prod.footprint()
>>> extent = s1_prod.extent()

>>>  # Specify a DEM to load DEM bands
>>> import os
>>> from eoreader.env_vars import DEM_PATH
>>> os.environ[DEM_PATH] = "my_dem.tif"

>>> # Load some bands and index: they will all share the same metadata
>>> bands = s1_prod.load([VV, VV_DSPK, DEM])

>>> # Create a stack with some other bands
>>> stack = s1_prod.stack([VV, VV_DSPK, SLOPE])

>>> # Read Metadata
>>> mtd, namespace = s1_prod.read_mtd()
```

Sentinel-3 and SAR products need [`SNAP gpt`](https://senbox.atlassian.net/wiki/spaces/SNAP/pages/70503590/Creating+a+GPF+Graph) to be geocoded.
Ensure that you have the folder containing your `gpt` executable in your `PATH`.

## Documentation
The API documentation can be found [here](https://eoreader.readthedocs.io/en/latest/).

## Examples

Available notebooks provided as examples:

- [Basic tutorial](https://eoreader.readthedocs.io/en/latest/notebooks/base.html)
- [SAR data](https://eoreader.readthedocs.io/en/latest/notebooks/SAR.html)
- [VHR data](https://eoreader.readthedocs.io/en/latest/notebooks/VHR.html)
- [Water detection](https://eoreader.readthedocs.io/en/latest/notebooks/water_detection.html)

## Installation

### Pip

You can install EOReader via pip:

`pip install eoreader`

EOReader mainly relies on `geopandas` and `rasterio` (through `rioxarray`).

On Windows and with pip, you may face installation issues due to GDAL.
The well known workaround of installing from [Gohlke's wheels](https://www.lfd.uci.edu/~gohlke/pythonlibs/#rasterio)
also applies here.
Please look at the [rasterio page](https://rasterio.readthedocs.io/en/latest/installation.html)
to learn more about that.

### Conda

You can install EOReader via conda:

`conda config --env --set channel_priority strict`

`conda install -c conda-forge eoreader`

## Authors

**EOReader** has been created by [ICube-SERTIT](https://sertit.unistra.fr/).

## Credits

**EOReader** is built on top of amazing libs, without which it couldn't have been coded:

- [`geopandas`](https://geopandas.org/)
- [`rasterio`](https://rasterio.readthedocs.io/en/latest/)
- [`xarray`](http://xarray.pydata.org/en/stable/)
- [`rioxarray`](https://corteva.github.io/rioxarray/stable/)
