Abstract: Through the understanding of cartography as an alternative representation tool, this paper researches the existing and usually invisible relationships between informal micro-activities and formal public spaces. For this purpose, Carapungo Entry Park located in the north of Quito (Ecuador), is taken as a case study, being a paradigmatic case of the complexity and multiplicity that constitutes informality in Latin American cities. After a first analysis based on the formal planning of this park, we will focus on dissident spatial practices carried out by inhabitants who occupy and appropriate a formal space. These situations of conflict originate spatial constructions based on spontaneity, fluidity, adaptability, movement, and temporality, which include local culture, economy, and social interaction. With the production of cartographies, the processes and activities generated by formal and informal vendors, passers-by, and public transport passengers, are made visible and analyzed. The expected results based on cartography as an alternative representation, are the presentation of relations of tensions, forces, conflicts, and negotiations that allow us to identify patterns, trends and behaviors that have no place in the supposed precision and rigor of the regulations in the formal planning of public space.
