REVITALIZATION AS AN ACTION IN SPACE – CASE STUDY OF LARGE CITIES IN POLAND AND BULGARIA

Abstract

The main goal of revitalization is to improve the spatial condition of the city, which improves its image and increases the value of space. Any revitalization process requires the acquisition of geolocation data. This data can help visualize the spatial changes that were the goal of revitalization efforts. Acquiring such data is not always easy and requires the use of multiple sources of GIS information. The purpose of this paper is a spatial presentation of the analyzed areas with their identification before and after the revitalization process using GIS tools. Data is presented for two cities: Bydgoszcz (Poland), Varna (Bulgaria), characterized by a similar population. The paper uses current and archival orthophotos of the revitalized areas, Street View panoramic views from street level and own photographic documentation. The results of the analysis show that regardless of the stage of revitalization, the use of spatial data is essential in the designation of a degraded area, as well as later in its design, monitoring and management.
