## 3 Methodology and Database  
The comparative analysis of two regional centres, with relatively identical characteristics in terms of the development of functional areas but differences in terms of geographical characteristics and the spatial extension of the research area, based on the influence of the spatial arrangement of creative industries, involves the development of a methodology of research to capture the conditional relations between the location of the industry and its impact in the territory as well as the impact they have on the human component as a direct beneficiary of the harmonious development of the urban territory. Taking into account these defining requirements, a proprietary research methodology was developed and implemented in the GIS environment on numeric, vector, and raster database structures. This methodology, which takes shape as a GIS of complex spatial analysis, allows for the integration of the principles of development and regional planning in functional systems of response-process type for the analysis of specificity and territorial development. The developed methodology has at its centre the evaluation of the territorial specificity based on the analysis of pedestrian accessibility to the infrastructure of the creative industry, considering that the infrastructure of the creative industries generates additional territorial value through economic growth and a small negative impact on the environment due to the specificity of economic productivity and non-polluting matters. Thus, the analysis of urban centres from the point of view of pedestrian accessibility of the population emerges as a defining factor in the establishment of functional urban areas due to the fact that easy pedestrian access will lead to the development of the spatial component, which takes into account the reduction of transport infrastructures necessary for transporting the human component to the workplace and implicitly significantly reducing the intense traffic generating territorial dysfunction. Having in its centre the assessment of pedestrian accessibility, the spatial analysis methodology is structured in three distinct stages (the acquisition of numerical database and spatial databases; the implementation of the proposed GIS spatial analysis; and the analysis of the intermediate results and presentation and analysis of the final results to identify areas with dysfunctions in order to issue their remedial solutions). These stages, when viewed as a whole, take shape as a complex system of spatial analyses that cannot function without referring to, within the research approach, the spatial databases and the results obtained in the previous stages and sub-stages (Figure 2). Figure 2: The scheme of the methodological workflow. The first step within the spatial analysis process is the acquisition and creation of a GIS spatial database on which the entire research process is based. The databases used in the spatial analysis process are divided into two different structures: vector databases representing the network of communication paths obtained on the basis of direct acquisition from OSM, and alpha-numeric databases representing the spatial localisation elements of each unit entity that represent a certain type of creative industry. Considering the fact that the entire research approach is based on pedestrian accessibility, the vector databases representing the communication paths were subjected to the process of spatial analysis on the attribute table to obtain the time in minutes required for the movement of a person on road segments--times that together highlight the areal access to the locations of the creative industries. The preparation of the vector database representing the communication paths involves the use of the average travel speed of 5 km/hour, related to metric distances.
