# 3. Get Satellite Imagery

The diagram below shows how to fetch historical Satellite Images and receive newly acquired ones as they become available in GeoPard.

GeoPard supports several providers, including Sentinel-2, Landsat 4/5/7/8/9, and Planet. You can fetch Satellite Images with generic queries such as `getFarms` and `getFields`, with the relevant data located in the Field entity ([Request 1 or R1](/geopard-tutorials/api-docs/geopard-api-requests-overview/3.-query-get-satelliteimages.md)). API consumers can filter Satellite Images by date range, provider, cloud coverage percentage, and rendered geo map types.

To stay updated on newly acquired and processed Satellite Images, the GeoPard API sends subscription events through WebSocket ([Request 2 or R2](/geopard-tutorials/api-docs/geopard-api-requests-overview/1.-subscription-get-events.md)). When you receive a `MODIFY` event for a Satellite Image on the relevant field, that image is ready for collection from the GeoPard API by its UUID ([Request 3 or R3](/geopard-tutorials/api-docs/geopard-api-requests-overview/4.-query-get-defined-satelliteimage.md)).

This event-driven architecture ensures API customers are notified promptly and can access the latest Satellite Image as soon as it is processed and available.
