THE PROCESS OF URBAN REGENERATION

The complexity of the processes of urban regeneration derives from the difficulty the city built with all of them to reorder their conditions and

restrictions, which seem insurmountable, when it is a matter of transforming areas into big cities.

It is basic to incorporate tools of digital cartography and GIS to describe the urban reality with all their attributes, in order to show the background and essential referents to study every case and to define

an adequate intervention, that answers to the citizens needs, of a feasible form, in the processes of urban transformation.

In the geo-referenced area of the Barcelona’s extension



• The cities with a high level of consolidation in their centers, needs to recover part of the central spaces in order to clear the built space and generate new civic spaces, gardens, squares, cultural centers, social or sport equipments, etc.

• The application of the GIS to study the urban reality, the characteristics of the spaces, the evaluation of the needs, social demands, the potential use, the tours in front of patrimonial or singular buildings. Precisely a a simulation of the capacity of regeneration of specific interventions.

• In the LMVC of the CPSV of the UPC we have developed a methodology, to confront processes of urban regeneration, that facilitate the access to the information for the decision making and control of the management with GIS.

•The Barcelona’s extension “Eixample de Barcelona” was projected by Ildefonso Cerdá in 1860 and was developed in the the time whit a lot of difficulties.

7



• The original project was modified, and actually is a very central zone in the city whit a complexity in their activities and characteristics: Their main problem is the over-construction in height and the deterioration of some of their interior courtyards of blocks.

8

THE EXPERIENCE IN BARCELONA’S EXTENSIONIn Barcelona, this need for regeneration is orientated to recover part of the interior courtyards of the blocks of the Eixample, since many of them are very deteriorated or they are underused. This initiative of the Town Council of Barcelona is developed by PROEIXAMPLE S.A. through a city planning:

Transforming the courtyards and to convert them in urban open spaces, for that at least one of every nine blocks of the Eixample it has an interior urban open space and to assure the neighbors a green zone to less than 200 meters of their house.

That requires an exhaustive knowledge of the constructions, activities, occupation or abandonment of the interior spaces, thus as conveying all the process of transformation (change of owners, redefinition of the space, etc...) with the treatment and management of a great volume of information, functions that the GIS, which facilitates the study plunges, visualization of every stage and the decision making on where and as acting.

PLAN GLOBAL DE RECUPERACIÓN DE INTERIORES DE MANZANA.GLOBAL PLAN OF RECOVERY OF INTERIORS OF BLOCK.

With the integration into a GIS of the different available bases in PROEIXAMPLE and others of Municipal area, the visualization of the urban space, the management and consulting of information related to the pre-existences of the different centers of block, and to their appropriateness is facilitated or not to be transformed into green zones.

It is basic to document all the process and to access to the information in every phase, to facilitate its look-up and the materialization of the results of these in images and maps.

FUNCTIONALITY OF URBANISTIC MANAGEMENT

The information system incorporates all the graphic entities that affect in the “management”, to those that is assigned to them the necessary contents to complete the process of control of ProEixample, on the transformation of the courtyards of interior of block.

AMBIT POLGES

It is identified through the code of plan and the graphic entity is linked to the data of planning: suggested determination, organisms, formalities, approval date, allegations, rectified texts, etc...

It is an entity that groups together one or more owners that are going to modify the property holder, through a system of management isolated as a cession or isolated expropriation or a grouping of several lots with a same system.

It originates from the intersection of initial Lots with the Polygon of management, the result will be the part of the lot, the one that really is seen affected by the planning, affected.

RESULTS AND CONCLUSIONS

A model of integration of data develops geo-referenced in a GIS channeled to processes of urban regeneration. It defines a structure of bases of urban information of the Eixample of Barcelona (of property register, of census of inhabitants, etc…) capable of providing descriptors as for lot, related to the structure of the property, predominant uses, activities and occupation, among others.

Outlining a methodology and a practical procedure for the incorporation of the urban characteristics in a GIS that improves the follow-up and control of the stages that concern the processes of transformation or regeneration of the city in a specific urban area of Barcelona.

At all times it allows to carry out a follow-up (registers) continued of the process of regeneration, on the base of a general information and of detail that allows to incorporate new contents up to its complete execution, so that PROEIXAMPLE S.A. has a precise vision of every stage of the process.

The tool Geomedia allows facilitating this task in so far as it is the program that allows first of all the linking of the data, the selective consulting of information represented on the reality, as well as the construction of space relations among the urban characteristics and a follow-up of the process of urban transformation.
