The WindowMappr© was developed to make spatial challenges connected to landscape and land use tangible, visible and easier to discuss in a low‑threshold way that stimulates interaction, reflection and co‑creation, both in educational settings and in practice, where digital participatory mapping tools are often too technical or distant for quick, collaborative use. Its simple and consistent setup makes it broadly applicable across contexts, supporting spatial thinking in education and facilitating the exchange of knowledge, experiences and perspectives in participatory processes without requiring technical expertise. This document provides a practical guide for constructing the WindowMappr© and outlines its basic principles of use.
