Main application goals* A new Approach for the Ecological GIS Synthesis and Analysis.

* Preparation of requirements to the GIS environmental application;

* Ensuring the available data;

* Requirements to the databases structures and contents have to be established.

* Preparing of the graphic database.

* Creation an environmental GIS application using the "Hierarchical Point to Point Model" (HPPM) of the real World which is especially created for the goals of the URBAN Project and a new relevant methodology, developed by Technical University of Varna, Department of Computer Sciences.

* Sharing the collected experience with organizations, companies and universities.

Application uses graphic and text data of the City of Bourgas with an area of about 1500 hectare.

Municipality of Bourgas• Municipality of Bourgas is situated in Eastern Bulgaria on the Black Sea

seaside and has territory of about 48 200 hectare. It includes the City of Bourgas and other 12 small villages. The region is one with a best developed industry in Bulgaria - oil refinery, machines building, cables production, ship yards, food industry, harbour - totally 35 big industrial plants. The city has an airport and is a big railway and road traffic centre, too. The City of Bourgas consists of 8 housing regions with more than 236 000 inhabitants, an area of about 2800 hectare with a built housing area of 843 257 m2, 72 930 lodgings.

ECOURBAN GRAPHIC DATA BASES

• Cadastral maps in M 1:500 and M 1:1000.

• National coordinate system - 1950 coordinate system.

• Created by digitizing, GPS measurements.

• Created and supported as .DWG files

• BASE MAP of BOURGAS.• Created using the properties of City Center Map.

• .DWG file.

• Reduced number of layers

• ArcView Themes. • Created by separating and importing of AutoCAD layers.

Impact

• Modern technology transfer.• Way to develop global GIS solutions for our Municipality.• Data collection and actualization.• Contacts to potential GIS users.• Modern local government solutions.• Cooperation between local government, state authorities,

business, NGO’s.• Better service of citizens.• Successful international cooperation and future common

activities.• Better conditions for successful Bulgarian EU admittance and

participation.

Conclusion

• ECOURBAN is a real GIS, which works in Bourgas Municipality in Bulgaria. This Information Technology supports the quality government decision making process in a very important area – Ecology.

• Generally, we think, that the ECOURBAN Project will ensure co-operation between municipalities with similar problems and infra-structures based on the new modern managerial and Information Tech-nologies. This way we hope to have more effective and useful relation-ships between our regions for a successful development and better opportunities for our citizens. ECOURBAN will outlive the Project and can be classified as a very classical GIS OF TOMORROW.
