The pejorative interpretation in the collective imagination of describing a coastal tourist destination—or the public space within a tourist area—as “mature,” “consolidated,” “pioneering,” “stagnant,” “saturated,” “experienced,” “in the final stage of growth,” or similar terms according to the various evolutionary theories, implies that it is at a decisive, critical, and highly uncertain juncture. This is because the destination is beginning to show signs of exhaustion. This leads to a loss of appeal and market share compared to other destinations, as well as a decline in the tourist experience it provides, with the consequent impact on key indicators of the tourism business and profitability (tourist arrivals, number of overnight stays, average length of stay, spending and occupancy rates, average daily revenue per available room, etc.). Therefore, following the sequential process of generation-degeneration-regeneration, this situation, if left unchecked, can become the prelude to this final stage, with the consequent decline, and even, if prolonged, its decay. The term "obsolete tourist destination" refers to this situation. This obsolescence (physical, functional, business model, organizational model, segmentation methods, sales channels, etc.) of public space is usually a consequence of its morphology, utility, or functionality becoming insufficient or being surpassed by the tastes, motivations, and demands of the market and, consequently, by new market trends to which it cannot adapt and respond. Furthermore, the quality of a tourist destination, a tourist area, or a zone (micro-destination) within it is not limited solely to its private spaces (accommodations and complementary or service facilities), but also extends to the urban environment. Thus, the urban tourist space increasingly becomes the element that produces a tourist experience and allows visitors to enjoy all kinds of events, thereby influencing the level of customer (tourist) satisfaction and the tourist image. Likewise, the quality of the urban environment is becoming an increasingly important differentiating factor for the destination. The regeneration of urban-tourist spaces seeks to establish comprehensive and intelligent transformation strategies. These must encompass everything from restructuring the range of activities and services offered within them to designing the urban environment in line with the needs of the tourist destination as a product, the requirements of the tourist (customer), and the paradigm of sustainability, understood as a strategy for its renewal. Furthermore, urban-tourist areas constitute complex, heterogeneous, and dynamic territorial environments; this means that any regeneration process requires territorial classification, as it allows for the identification of areas with similar characteristics that require analogous solutions. Furthermore, given that the quality of a tourist destination is closely linked to that of its surrounding environment, understanding its urban reality is crucial for developing comprehensive, sustainable, and intelligent renewal strategies that transform the destination by implementing the most appropriate dynamics for its improvement. For both of these issues, studying public space through urban sustainability indicators can help evaluate transformations and determine the impact of regeneration strategies and projects. However, while numerous indicators exist for certifying the quality of tourism products and services, indicator systems that measure the sustainability of the activity—in relation to issues such as carrying capacity, energy and water consumption, and even the social impact of the activity on residents—as well as parameters that allow for analyzing the quality of the urban environment, these do not take into account some fundamental qualities necessary for enhancing the value of urban tourist spaces. This is because coastal urban tourism generates specialized territorial areas with their own characteristics and unique forms of urbanization that distinguish them from traditional urban spaces. Therefore, it is necessary to revise the criteria for evaluating public space in coastal tourist areas, especially to integrate them into current paradigms of urban sustainability and so-called "smart destinations." The main objective of this project is to propose comprehensive, innovative, and intelligent strategies and actions for the competitive repositioning and regeneration of public spaces in the Canary Islands' outdated tourist areas, from the perspective of the tourism product, multifunctionality, and urban sustainability (in its three dimensions). To this end, the formal and spatial parameters that make up urban spaces will be modeled in order to identify their characteristics, as a preliminary step to evaluating their urban sustainability, as well as the degree of efficiency of the actions implemented or planned. This project is conceived as a continuation of the project “Geographic Information Technologies applied to the analysis and design of innovative proposals for the renovation of tourist accommodations”, granted by the CajaCanarias Foundation (2015 call), focused on the renovation of the private space of tourist areas, specifically, tourist accommodation.
