Today we'll demonstrate how to split a raster image in QGIS.

In this tutorial ill use a raster from the Massachusetts buildings Data set. Thanks to Dr.Volodymyr Mnih   Mnih for we can access this data set    

Step 1: Open Qgis and add the raster Layer

Step 2: Right click on the layer, export, save feature as:

Step 3: Tick the vrt option, once you tick it a new option will be addedwhere you can specify the height and width of the tiles. I suggest that you leave the other values as defaults

Step 4: Save your output to a destination folder. Once the execution is done , your can import any tiles you want to use in your analysis.
