When we have a lot of images taken by drones and want to slice them and publish them to the intranet, what tool can we use to slice them? Or is there any tool that can be used to slice and publish the map you made yourself? To solve these problems, you can take a good look at this article. This article will provide you with a simple slicing method, I hope it will be helpful to you.
Install plugin
On the QGIS menu bar, plug-ins, select Manage and install plug-ins, as shown in the figure below.
Select Manage and install plugins
In the displayed plug-in dialog box, select the Install from ZIP file tab and select the location of the plug-in. Click Install Plug-in to complete the installation of the plug-in, as shown in the figure below.
Select the location of the plugin
Of course, you can also click on all tabs and directly search for QMetaTiles to install the plug-in, as shown in the figure below.
Search and install plug-ins
image slice
Click "Plugins\QMetaTiles\QMetaTiles" on the menu bar, as shown in the figure below.
Select QMetaTiles
In the displayed QMetaTiles dialog box, set the directory where the exported tiles are located in Output, set the Tileset name according to your own needs, select the range of the image to be sliced in Extent (the image needs to be loaded into QGIS first), and Zoom is the exported The level of the tiles is set according to the resolution of the image. The image I used here has a small range and high resolution, so I set it to levels 15-21, as shown in the figure below.
Slice settings
Click OK to start slicing. After slicing is completed, open the set directory to see the generated slices. The generated slices are as shown in the figure below.

It should be noted that no matter what coordinate system your image is in, the exported tile coordinate system is the tile in the Mercator coordinate system.
In fact, if you need image slicing, you can also use our water course micromap for slicing. First, load the image into the water course micromap through an offline map.
Add offline map
After adding it, just like downloading the map, create a new task, and then select tiles as the export format. We can see that there are many kinds of tiles available for export, as shown in the figure below.

Conclusion
The above is the detailed description of the image tile cutting tool QMetaTiles, which mainly includes functions such as installing plug-ins and image slicing.
