Yogyakarta is a tourism city with increasing number of tourists. This result to the area surrounds points of interest turning into business and trade area. The growing business and trade sector induces the tendency to use signage for advertisement. The problem is, the existence of that many signages somehow have covered up the face of Yogyakarta as a cultural heritage. There are so many occurrences of misused signage, varied from misplaced signage to installing unauthorized signage. Furthermore, another problem occurs from the visual aspect of the city, because signage instalment affects the aesthetic of the street corridors. Therefore, a research in field of organizing signage must be conducted based on visual aspect. This research is aimed to create an organized design of signage that is appropriate according to visual aspects (colour, form, line, texture, and scale). This research is also using descriptive method in the form of policy analysis and evaluative analysis through Visual Impact Assessment. The result of this study is formed as how much the signage impacts visual aspect and then developed into an input for creating signage design and adapted to the policy.
