Abstract

In line with the objectives established by the "European capital of culture" initiative, the entire community is involved in embarking socio-economic and infrastructure projects supported by an information platform which ensures efficient data management for the municipality. This platform should provide a good visibility of the candidate city in the context of enhancing the contribution of culture to its long-term development in accordance with its priorities and strategies. In particular, an important role is played by the implementation of a spatial data geoportal at Local Administration level (Timisoara City Hall) to streamline the data workflow and provide easy access to it in order to increase the visibility of cultural and historical heritage of the municipality. The need of this geoportal arises from the fact that Timisoara has the widest architectural heritage area in the country, of important value to both Romania and Europe. The preservation of this cultural heritage is a duty for the authorities and also for the owners. The present paper brings forward proposals and trends in implementation of a dedicated geoportal for the management of heritage objects to complete the existing urban GIS primarily aiming to contribute to fostering the urban planning and the sustainability of the "European capital of culture" project. This geoportal should include the 3D models of the cultural heritage objects for better preservation over time or restauration purposes and offer virtual tourism tours if they are made available by means of webGIS. That is why, the authors propose a webGIS solution in order to make the geoportal available on the City Hall's webpage.

1. Introduction

The Timi§ County has a total area of 8,687km2 and is situated in the western part of Romania, on the border of three countries: Romania, Hungary and Serbia. The capital city of Timi§ county has a population over 300,000 inhabitants and besides being the most representative university centre of the area, Timisoara stands for the most important economic and cultural centre. Along the capital city - Bucharest, Cluj-Napoca and Ia§i, Timisoara is one of the biggest cities of Romania.

Located in the western plains, throughout history the city was the capital of Banat, a region populated mostly by Romanians, who cohabited in harmony with other ethnic groups such as Germans, Hungarians, Serbs, Hebrews, Turks etc. On the other hand, its location in the Banat plain, has as disadvantage, the fact that natural resources are poor, so the richness of the region consists in the architectural and touristic potential, [1].

As a national strategy, a key component in the policies of growth poles is promoting urban development, through the development of sustainable transport. According to national legislation, urban mobility plan represents a complementary documentation to urban/Metropolitan territorial development strategy and to the general urban plan, but also the territorial strategic planning tool by which spatial development of localities is related to the mobility and transportation needs of persons and goods. Sustainable urban mobility plan covering the growth pole in Timisoara (Fig. 1) consisting of the city of Timisoara and 15 adjacent villages and concerns the following joint strategic objectives: accessibility, safety and security, the environment, economic efficiency and the quality of the urban environment.

(2005-2050).

Sustainable urban planning is the one that seeks to minimize the negative environmental impact of buildings by efficiency and moderation in the use of materials, energy, and development space. It uses a conscious approach to energy and ecological conservation in the design of the built environment with a view of stimulating investments, attracting tourists and increasing the living standards of inhabitants.

To support the candidacy of Timisoara to the "European capital of culture" through the vision and long-term measures proposed, the municipality's cultural strategy 2014-2024 was carried out. Moreover, the city's cultural strategy is a necessary condition of the application bid. The program stipulates that "the award title of European capital of culture will continue to rely on a cultural program created specifically for European capital of culture, which should have a strong European dimension. The program should also be part of a long-term strategy with sustainable impact on economic, cultural and social development".

By recognizing the role of culture for development and quality of life, contemporary cultural policies call attention to the need to inherently integrate the cultural sector in other areas of public life. Concern for the cultural life of the city of Timisoara implies a strong relationship between culture and urbanism, architecture, environment, education and contributes to local and regional development.

The city is prepared to invest in its heritage and to foster cultural phenomena. The potential offered by the Euroregion of historical Banat represents the foundation for the projects and initiatives meant to support the

development of a common identity based on a natural collaboration between people and organizations. Moreover, culture represents an investment for the local economy, which, through the development of tourism based on cultural heritage and on major events, aims to draw visitors and transform the city and the region in a cultural pole with wide international opening. With respect to candidacies to the "European capital of culture" initiative, from the 14 Romanian candidate cities, at present there are four cities remaining in the competition: Timi^oara, Bucharest, Cluj-Napoca and Baia Mare (Fig. 2).

2. Materials and methods

The City Hall of Timi^oara is the first institution in Romania starting the GIS [2, 3] for urban planning purposes [4] at present, being the most advanced city in this domain.

2.1. Background

The implementation of the GIS started in 1996 and covered a total area of 129.2 km2; 34 Cadastral Sectors; 900 blocks and 27000 property sheets. Main objects defined in this Urban Information System of Timi^oara are illustrated in figure 3:

Positioning of each entity is made on the reference given by the cadastral digital plan, 1:500. Updating this plan is based on a photogrammetric plan by using existing records, parcelling projects, urbanism certificates, documentations from archives, documents on land retrocession, and modifications on the street scanning as a consequence of systematization etc. aiming to extend this system throughout the metropolitan area. An eloquent example of updating of the database for the Urban GIS (fig. 4) implied the acquisition of all information regarding the cemeteries, a project carried out between 2007 and 2009, [5].

2.2. Trends regarding the Timi§oara urban GIS

A benefit the Urban GIS should meet its potential customers with is the possibility to access data using the Internet. It is a simple solution, useful, which incorporates cutting-edge technology that brings local, regional or county Administration closer to citizens. This concept, relatively new, is already being implemented in a number of towns in developed countries. As nowadays everybody has access to Internet, the WebGIS could provide residents and tourists, information of public interest, such as: recreation areas (museums, theatres), accommodation (hotels, restaurants), geodemographic and economic information, public transportation, healthcare system, specific local information and, of course, historical areas. The digital maps represent a support of an easy management of urban infrastructure and of geospatially distributed resources from the administered territory. At the same time, the WebGIS allows easy updating of databases and automatic generation of reports and statistics. Some of the main advantages are:

• obtaining orthophoto plans; scanning and georeferencing urbanism plans, old land register plans, architectural plans; designing complex urbanistic plans, all this information being of great aid to officials within the various compartments of the City Hall, in resolving problems quickly and in day-to-day activity;

• the use of digital cadastral map of the built-up area allows editing and issuing layout plans and other plans required by the citizens, even at the time of application;

• use of specific applications for efficient management of street names, the houses numbers, accurate records of properties and property owners, simplifying their administration.

• for Communal Office: realizing the inventory of urbanistic data records through the development of applications such as: green areas cadastre, road cadastre, an integrated system of urban cadastre together with urban services.

• the possibility of the Tax Bureau to determine the correct criteria for taxation of real estates;

• for the Heritage Office: management of cadastral and land book data to accurately identify heritage data or public and private properties of the City Hall.

3. Results and discussions

The authors propose a workflow diagram (fig. 5) with the actual working process for creating the 3D cultural heritage model, step by step, to be used in the geoportal [2].

As regards the creation of the 3D models of cultural heritage objects, there are several technologies available for data collection: close-range photogrammetry, laser scanning, UAVs (Unmanned Aerial Vehicles).

Fig. 5. Workflow diagram - logical scheme.

For processing and creating 3D models, the alternatives are: model in specialized software (e.g. Cyclone, Solid Scan, GeoVerse, JRC 3D Reconstructed), model directly in 3D CAD, (Civil 3D), model only surface (for pure restauration purposes - created from photographs - Corel Draw).

For the present objective the data was collected with Leica CIO Scan station. The scanning survey may be divided into three phases: planning, scanning and registration and QA/QC (Quality Assurance/Quality Control). In the processing phase, the scans from different stations are brought in a common reference system and then merged to create a complete model. During this process, registrations are created, namely target to target or cloud to cloud registration in order to obtain the unified point clouds (fig. 6) and clear the noise.

After the 3D models of the cultural heritage objects are created, they should be uploaded on the geoportal [7] in order to appear when it is interrogated. Also, as attributive data of the cultural heritage objects, the authors suggest a brief description of the object's history (fig. 7).

From the applicative point of view such a WebGIS solution brings added value for all the institutions that manage and operate with Cultural Heritage objects. The fact that information is available at a glance as a WebGIS resource for different users in an attractive and intuitive manner, it provides a powerful tool for cultural heritage conservation as an efficient strategy of urban planning.

4. Conclusions

This paper does not pretend to be a thorough study or a monograph, but rather an analysis on the Urban GIS evolution of Timisoara. Many of the aspects of the public administration (health, infrastructure, planning, development, disaster management, security, crime, environment protection, education, culture, recreation) or private (control of distributed resources and facilities: transport, telecommunications, electricity, petro-chemical, distribution and marketing) involve geospatial data, for which the Urban GIS provides developed management resources by means of the updated database. The authors insist on the idea of creating a geoportal for cultural heritage objects as the future brings changings in terms of replacing desktop solutions by WEB solutions in order to allow the dissemination of the results and to increase the possibility of international collaboration between specialists. WebGIS solutions have several advantages among which we mention the access to spatial data characteristic to cultural heritage documentation either for specialists or ordinary users and different purposes.

An efficient urban planning strategy implies creating WebGIS for cultural heritage as the next natural step forward for both conservation and preservation of these objects, and also for understanding and promoting them. Also, together with the unlimited possibilities offered by the World Wide Web, creating physical virtual replicas of Cultural Heritage objects has become more and more attracting and interesting.
