# GUI Grounding Pre-training Data for OS-ATLAS
This document describes the acquisition of the pre-training data used by OS-ATLAS.
***
**Notes:** In GUI grounding data, the position of the target element is recorded in the `bbox` key, represented by `[left, top, right, bottom]`. 
Each value is a [0, 1] decimal number indicating the ratio of the corresponding position to the width or height of the image.
