The Master Plan Study on JICA Integrated Environmental Management in Baku City in Azerbaijan Republic KOKUSAI KOGYO CO., LTD. 1.3 Establishment of GIS Database 1.3.1 Introduction Information that is to be dealt with in environmental management is diverse and exists in various forms such as digital, texts, tables, maps and photographs. Information in inconsistent forms is, however important, difficult to efficiently utilise for intended purposes. Therefore, information integration is vital and nowadays, a geographical information system is widely considered indispensable. The GIS establishment at the BCE is one of the key tasks assigned to the team. The team has attempted to examine the purpose of database utilisation, methods of use, important areas, database items, data forms, and other elements of the database structure. The database particularly contains data on the environment, and will be fully used by the BCE. 1.3.2 Database Structure The environmental database structure established in this project consists of six main categories (refer to Table1-1). These databases were developed in Azerbaijan with the help of a local sub-contractor: (1) base map, (2) information on natural resources/conditions, (3) information on social resources/conditions, (4) environmental information - pollution source, (5) environmental information - ambient quality and (6) environmental information - pollution maps.
