## What it is
A Node.js library and CLI for downloading real-time images of Earth from the Himawari-8 geostationary weather satellite, which photographs Earth every 10 minutes. It stitches image tiles at various zoom levels and can generate timelapse videos with ffmpeg.

## Use cases
- download real-time satellite images of earth
- create timelapse videos of earth from himawari-8
- fetch latest weather satellite photo from japan meteorological agency
- download high-resolution earth imagery at different zoom levels
- get infrared satellite images of earth
- set satellite earth photo as desktop wallpaper automatically

## When to choose
- you want programmatic or CLI access to Himawari-8 satellite imagery
- you need tiled, zoomable earth images or timelapse video generation
- you want a simple npm package with infrared and date options

## When to avoid
- you need imagery from satellites other than Himawari-8
- you need a maintained project - the latest release was in 2021
- you need real-time streaming data rather than periodic snapshots

## Facets
- artifact type: library
- maturity: maintenance
- function: image-processing, cli, http-client
- domain: data-science, developer-tools, media
- platform: cli, cross-platform
- tags: satellite-imagery, himawari-8, earth-observation, npm-package, timelapse, nodejs
