Ever since the year 25,000 B.C.E, when the first known map was carved into a Mammoth tusk, map makers have relied on geometric symbols derived from nature in order to represent a geography. However, even though modern digital cartography brings about endless possibilities for map customization and visualization, the art of utilizing geometric symbols in maps has been all but forgotten in the era of modern map design.

In order to resurrect, appreciate, and preserve the art form of geometric patterns derived from nature, and to incorporate them in a nuanced form within modern digital cartography, we present Mapajoara: a self-contained free and open source interactive map of Belém integrating indigenous Marajoara iconography into the underlying map interface, using ancient drawing patterns to represent different geographic and urban elements.

Each Marajoara pattern appearing on the map has been studied and carefully selected to symbolize rivers, forests, urbanized areas, and other significant aspects of Belém, offering a visually distinct and culturally enriching experience to users. Our project not only highlights the beauty and importance of Marajoara art, but also promotes interaction and learning about the geography and culture of the region through a modern and accessible technological platform.
