Figure 3. Ranking of the appropriate use of cartographic changes for the touristic mapping (Salomão Graça, 2015). Cognitive changes must be aligned to the control elements (target audience, purpose, geographical reality, the mapping scale, technical limits) and to graphic elements of the mapping project (clarity and readability, visual contrast, picture and background, equilibrium or balance, and hierarchical organization of information). In this context, the touristic Web-Map needs to worry about the generalization process (composition of various scales) of cartographic project, with distinct, clear and highlighted symbols in relationto the map background. To perform a proposed generalization in computer systems targeted to the touristic cartography, a set of questions must be answered, addressing theoretical, specific computational elements (philosophical goals); the geometric conditions, spatial measures, and the operation controls (cartometric evaluation of material); and the respective geometrical (space) and content (attributes) operators to ensure an effective result, as proposed by the scheme formulated in Figure 4, from considerations of McMaster and Shea (1992). Figure 3. Ranking of the appropriate use of cartographic changes for the touristic mapping (Salomão Graça, 2015). The generalization process is essential for the touristic cartography because the products must have as main objective the graphic clarity enough to establish the desired cartographic communication, or in other words, the legibility of the map. Thus, the exaggerated /disproportional representation of elements, fatally damages the clarity of the document (Fernandes & Salomão Graça 2014). Generalization operators are used to promote changes in geometry and content of cartographic features in order to make them lighter during the reading process, eliminating visual pollution which endangers the reader's interpretation about the information. In this process the nature (or dimensionality) of cartographic information can be changed to meet the
