What is DINUR?
DINUR | DINÁMICAS URBANAS is a method for analyzing urban dynamics through Big (Geo)Data for the Regeneration and Transformation of the city. , Technology and Innovation. It is a project financed by the Gipuzkoa Provincial Council through the 2022 call for the Support Program for the Guipuzcoan Network of Science, Technology and Innovation.
It is a first approximation focused on the visualization, spatial analysis and modeling of urban dynamics through the application of Geographic Information Systems with new data sources.
Objectives, methodology and results
The main objective of this proposal is to take the pulse of the city, analyze the stay of people in the city; emptied and filled applied to the city of Donostia – San Sebastián. Approaching the study of the real use of public space, identifying and geolocating urban dynamics.
An exhaustive analysis of all the sources related to the field of research is carried out to lay the foundations of the proposed method. The methods for obtaining data with a spatiotemporal component are selected and defined and classified in a matrix grouping them by occupancy patterns (Google Places, Google Maps), dynamic consumption areas (bank details, mobile data), mobility (bus stops, , transport nodes and routes); urban landmarks (Instagram); tourism (Flickr, Tripadvisor, Airbnb). The method is applied to the case study of Donostia-San Sebastián obtaining a sequential visualization of the data.
As an expected result, a sequential visualization of the different data sources that represent the urban dynamics of the city of Donostia-San Sebastián will be obtained.
Future lines of research
DINUR is based on the knowledge and tools acquired in the RISAU project (Towards the healthy city, Method to assess the Health Risk associated with the Urban environment where the characteristics of the built space were analyzed through 23 indicators with the aim of identifying areas most vulnerable urban areas because they are not adequate to promote active mobility, do not have sufficient environmental quality or do not provide spaces for stay and social interrelation.
Given the correlation of the projects, it is not ruled out to determine which are the explanatory variables for these new dynamics (DINUR) based on the physical parameters of the city (RISAU).
