Since Galileo, astronomers and planetary scientists work hard to draw accurate representations of planetary surfaces. Planetary mapping today is a tool of geological investigation, landing site selection and also a visual statement of our ever expanding horizon of discovery. From copper engravings to dynamic online maps, the technique of presenting planetary maps changed a lot. In this presentation I will show some early examples of how planetary maps can communicate unspoken preconceptions (no, its not the canals), and show how we mapped the Navua Valles, which may have episodically provided habitable environments on the inner rim of Hellas Basin on Mars. The talk is part of the International Map Year celebrations.
