 To generate new road images, follow the next steps:
 
 * Create a new road or edit an existing one using the [OpenRoadEd](https://gitlab.iri.upc.edu/mobile_robotics/adc/openroaded) tool. See the documentation on this link for more information.
-* Create a screenshot of the desired road. 
+* Create an image of the desired road using the take screenshot tool of the OpenRoadEd application. 
 * The screenshot is created as a 7000x7000 pixel image with a default resolution of 72 ppi (pixel per inch). Because of this fact, no matter what is the actual size of the real road, the screenshot equivalent size will be different. To *resize* the original image it is necessary to modify its ppi. To do so, compute the new ppi with the following equation, where *39.27* is the conversion from meters to inches:
