In archaeology, one of the most important aspect is the documentation of artifacts, which allows to study traditions and rituals of ancient populations. For architectural findings, as glyphs and petroglyphs, the identification and extractions is crucial, since these artifats can not be removed from the sites. Usually this task is perfomed by hand, so it is subject to human errors and it is very time consuming. Several automatic techniques have been developed to solve this problem, but a tool to onstruct realistic synthetic petroglyphs data will be useful to validate extraction algorithms and to create training data for supervised learning techniques. We will present a Matlab tool with a graphic interface that allows to create threedimensional realistic surfaces where petroglyphs have been carved. We will describe it, explaining how the user can select shape, position, and depths of the petroglyphs, in order to construct a desidered dataset, showing two possible surfaces that can be obtained.
