Copy/Duplicate and Split Tiles from an Imagery Mosaic

Updated

Plex-Earth 2026 introduces "Copy" and "Split" tools for Imagery Mosaic Tiles, enabling users to duplicate or separate selected tiles into new mosaics for easier management. These features, streamline handling large-scale mosaics and work with both fetched and unfetched tiles in supported AutoCAD and BricsCAD versions.

These tools are included in the following plans: Pro, Premium

Learn how to use the new imagery tools, "Copy" and "Split", introduced in Plex-Earth 2026. These tools are very valuable, especially for dealing with large scale Imagery Mosaics, and can help you manage them in the best way possible!

📝 Note: To use these tools, create an Imagery Mosaic first.

Tool 1: Copy Imagery Mosaic Tiles

With "Copy" Imagery Mosaic Tiles, you can copy selected tiles from an existing mosaic and duplicate them to a newly created one. To do this, you can follow this procedure:

  1. Open the Collection Manager → select the original mosaic → Edit.

    Locate Mosaic.png

  2. Select the preferred tiles you want to copy to another Mosaic.

    The selected tiles will appear with a red color.

    📝 Note: In case you want to copy the whole Mosaic, click directly on Copy, without selecting any tiles first.

  4. Select the provider → Next.

  5. Select your preferred Dataset → Accept.

  6. Name the new Mosaic → Accept → fetch the images.

Your new copied Mosaic is ready.

Tool 2: Split Imagery Mosaic Tiles

With "Split" Imagery Mosaic Tiles, you can split selected tiles from an existing mosaic and move them to a newly created one. To do this, you can follow this procedure:

  1. Open the Collection Manager → select the original mosaic → Edit

    Locate Mosaic - Split.png

  2. Select the preferred tiles you want to split from the existing Mosaic.

    Select Tiles to Split.png

    The selected tiles will appear with a red color.

  3. After the tiles are selected, click on Split. 

    Click on Split.png

  4. Name the new Mosaic → Accept.

  5. A message will appear. Choose whether to open the editor to review and modify the mosaic or not.

The final result is ready! The initial Mosaic is now split! You can see that both from the Collection Manager and from your drawing space.

After creating your Mosaics, you can see how you can edit them via this tutorial.

Also, if you want to insert your Plex-Earth Imagery Mosaics as Rasters and save them locally to your Hard Drive, you can use this tutorial.

📝 Note: Both the "Copy" and "Split" tools can also work without having fetched the tiles in the initial Mosaic. Therefore, you have the option to use these tools with unfetched mosaic tiles and then proceed with the fetching procedure. If you don't want to fetch the tiles of a Mosaic right away, you can choose the option "Edit Tile Selection", during the process of creating a Mosaic.

Tips & Notes

  • If you only need part of a mosaic for printing or exporting, copying selected tiles lets you keep the original intact.

  • Splitting removes tiles from the original mosaic, reducing the dataset size. This is helpful when working on huge or long projects.

  • You can repeat copying and splitting multiple times to organize imagery into logical groups.

FAQs

What's the difference between Copy and Split — which one should I use?

Copy duplicates the selected tiles into a new mosaic while keeping the original mosaic intact. Use this when you want a subset of tiles in a separate mosaic without changing your original. Split moves the selected tiles out of the original mosaic into a new one, permanently removing them from the source. Use this when you want to break a large mosaic into separate, independent parts. If in doubt, use Copy first to avoid unintended changes to your original.

Can I copy or split tiles before I've fetched the imagery?

Yes, both Copy and Split work on unfetched tiles as well. This means you can plan and organise your mosaic structure first, then fetch imagery only for the mosaics you need. To defer fetching, tick Edit Tile Selection during the mosaic creation process and skip the fetch step.

How do I copy the entire mosaic instead of just selected tiles?

Simply click Copy without selecting any individual tiles first. Plex-Earth will copy the entire mosaic to a new one. If you select specific tiles before clicking Copy, only those tiles will be duplicated.
