The current society is distinguished by its consumerism and rapid development, which has resulted in the emergence of numerous unutilized items. People concerned about this urgency, on the other hand, have joined a collaborative economy in which goods and services are shared amongst themselves, reducing desperation. With the widespread use of social networks, the emergence of communities and services managed in a distributed manner has grown. As a result, organizations such as Free Cycle and Community Exchange have emerged to aid in the search and exchange of goods. Following the example of these two groups and using available technology, this dissertation documents the development of a Geographic Information System with the goal of providing a web-based platform for the exchange of goods and services. This new approach, in which geospatial information is a key focus, allows users to view available products based on their location, increasing the probability of discovering products nearby. Aside from that, a classification of the user is implemented based on the products and services requested and offered, in order to increase the user's credibility in the eyes of the others, increasing the likelihood of a deal occurring. Throughout this work, the process is described, that is, there search carried out to gain a better understanding of the topic, the assessment of requirements, and the planning and creation of a prototype. To conclude, usability tests on the created solution were conducted in order to evaluate its performance and interface.
