SkyFi aggregates imagery from multiple satellite providers and offers various product types (sensor modalities). When searching or ordering, you will encounter the following options:

𝗣𝗿𝗼𝘃𝗶𝗱𝗲𝗿𝘀 / 𝗖𝗼𝗻𝘀𝘁𝗲𝗹𝗹𝗮𝘁𝗶𝗼𝗻𝘀:
The provider field or filter can include (but is not limited to) the following:

𝙎𝙄𝙒𝙀𝙄 (𝙎𝙐𝙋𝙀𝙍𝙑𝙄𝙀𝙒)– High-resolution optical satellites.
𝙎𝘼𝙏𝙀𝙇𝙇𝙊𝙂𝙄𝘾 – High-frequency imaging constellation (optical).
𝙐𝙈𝘽𝙍𝘼 – Synthetic Aperture Radar (SAR) provider.
𝙏𝘼𝙄𝙇𝙒𝙄𝙉𝘿, 𝙂𝙀𝙊𝙎𝘼𝙏 – Other optical imagery providers.
𝙎𝙀𝙉𝙏𝙄𝙉𝙀𝙇2 (𝙫𝙞𝙖 𝘾𝙍𝙀𝙊𝘿𝙄𝘼𝙎)– Sentinel-2 open data imagery (multispectral, 10m resolution, free).
𝙋𝙇𝘼𝙉𝙀𝙏 – Planet Labs imagery (high revisit optical).
𝙄𝙈𝙋𝙍𝙊, 𝙐𝙍𝘽𝘼𝙉_𝙎𝙆𝙔, 𝙉𝙎𝙇, 𝙑𝙀𝙓𝘾𝙀𝙇 – Additional providers (covering various types from stratospheric imagery to aerial or others, as integrated by SkyFi).

𝗣𝗿𝗼𝗱𝘂𝗰𝘁 𝗧𝘆𝗽𝗲𝘀: This refers to the type of data or sensor:
𝘿𝘼𝙔 – Daytime optical imagery (true color/RGB and possibly near-infrared; standard satellite photos in daylight).
𝙉𝙄𝙂𝙃𝙏 – Nighttime optical imagery (low-light imaging at night).
𝙑𝙄𝘿𝙀𝙊 – Satellite video footage (some providers can capture short video clips of an area).
𝙈𝙐𝙇𝙏𝙄𝙎𝙋𝙀𝘾𝙏𝙍𝘼𝙇 – Multi-band imagery (e.g., Sentinel-2 or high-res satellites with multiple spectral bands).
𝙃𝙔𝙋𝙀𝙍𝙎𝙋𝙀𝘾𝙏𝙍𝘼𝙇 – Hyperspectral imagery (many narrow spectral bands, typically special sensors).
𝙎𝘼𝙍 – Synthetic Aperture Radar imagery (radar-based imaging, can see through clouds, day/night).
𝙎𝙏𝙀𝙍𝙀𝙊 – Stereoscopic image pairs for 3D elevation extraction.

𝗥𝗲𝘀𝗼𝗹𝘂𝘁𝗶𝗼𝗻 𝗖𝗮𝘁𝗲𝗴𝗼𝗿𝗶𝗲𝘀: The API categorizes resolution into bands:
LOW, MEDIUM, HIGH, VERY HIGH, SUPER HIGH, ULTRA HIGH, and specific centimeter classes (e.g., CM 30, CM 50).

These categories correspond to the ground sampling distance (GSD):

Low might be 10 m per pixel (e.g., Sentinel-2).

High could be around 1 m per pixel.

Very High/Super/Ultra High implies sub-meter resolutions (e.g., 30 cm or 50 cm per pixel or better).

Each archive record will indicate its resolution category and often provide the exact GSD in centimeters (platformResolution or gsd field).

In summary, the SkyFi API acts as a one-stop interface to access many satellite constellations. You can specify exactly what kind of imagery you need (e.g., “I need a high-resolution SAR image from Umbra” or “a low-resolution multispectral image from Sentinel-2”) and the API will handle the request to the appropriate provider.
