## What it is
Satpy is a Python library for reading, manipulating, and writing meteorological remote sensing data from earth-observing satellites. It supports creating RGB composites from instrument channels and resampling data to uniform grids via the pyresample package.

## Use cases
- read and process satellite instrument data in python
- create RGB composites from weather satellite channels
- resample satellite imagery to uniform grids
- convert meteorological remote sensing data to image formats
- process GOES or other earth-observation satellite files
- work with satellite data using dask and xarray

## When to choose
- you need to read many satellite instrument file formats in Python
- you want compositing and resampling of meteorological satellite data
- you want an actively maintained, scalable solution built on dask/xarray

## When to avoid
- you need general-purpose image editing unrelated to satellite data
- you need a GUI tool rather than a Python library
- your data is not remote-sensing or geospatial imagery

## Facets
- artifact type: library
- maturity: active
- function: image-processing, data-science, etl, data-visualization
- domain: data-science
- platform: python, cross-platform
- tags: satellite-imagery, meteorology, dask, xarray, remote-sensing, rgb-composites, resampling, pytroll, earth-observation, satellite-data
