I think I need to add a bit more info for clarification.
The grid pieces will be procedurally generated, meaning that the sand tiles will be selected randomly as open tiles for the particular planet. The mountains will act like walls and will also be generated procedurally to create ravines, rooms, and other various containers. The sample I have provided is just one of nearly endless generations for a map and only part of a larger area it will create.
The space ship buried in the sand and the forge are tiles that the player can interact with, in this case both are used for a "salvage" skill which provides various mechanical parts and rarely tech constructs for use as part of that skill.
Monsters are also generated upon map creation and this is just a sample of what could be made.
