Work with Mosaics

You can view and download mosaics from the mosaics section of the platform, https://insights.planet.com/data/mosaics. Mosaics are composed of the Planet best daily images to provide a cloud-free comparison over time.

You can do the following:

• Find a mosaic: See the mosaic series and individual mosaics available to you.
• Compare mosaics: Compare two mosaics side by side to identify change.
• Pixel provenance: Identify which scenes contributed to the mosaic at a given pixel for more granular inspection.
• Download mosaic quads: Download mosaic quads to use in other tools.

note

To use mosaics, you must have a plan that includes access to them.

Find a series

Series are listed in the series tab.

• Filter by name - You can search for a series by typing in its name or a partial string into the "Filter by name..." textfield.
• Filter by cadence - You can filter the series based on cadence (weekly, bi-weekly, monthly, quarterly).

Find a mosaic

All mosaics are listed in the "All mosaics" tab in a flat list.

• Filter by name - You can search for a mosaic by typing in its name or a partial string into the "Filter by name..." textfield.
• Filter by cadence - You can filter the mosaics based on cadence (daily, weekly, bi-weekly, monthly, quarterly).

Compare mosaics

You can compare mosaics side-by-side and visually inspect change between two different time periods.

1. Click Compare imagery at the top right of the map.

2. Drag a mosaic from the list to the left side of the screen.

3. Drag another mosaic to the right side of the map to compare.

The mosaic date and name is listed at the bottom of each panel in the split screen.

Pixel provenance

Once you have selected a mosaic from the list on the left-hand side, you can inspect which scene contributed to a given pixel by using the pixel provenance tool on the right hand side of the map. A scene is a single image captured by a Planet satellite. Many scenes together compose a mosaic.

Download mosaic quads

A mosaic quad is a single square GeoTIFF, many of which together comprise a mosaic. You can download quads one at a time.

1. Click Open on a given mosaic from the list.

2. Define your AOI (either by drawing an area, or uploading a file).

3. Next to the ID, click Download.
