should be pointed out that most nonstandard queries will be realized manually by using a
tool such as ArcGIS Desktop. Actually, the DSS was already used for realizing several
queries described in Figure 1 (frame output).

4. Users and beneficiaries

Users of the system are divided into five groups: administrators, staff, scientists, tourists and
farmers, which own or rent parcels in the BNP. Additionally, staff members - about 100
people - are divided into eight subgroups (management, accounting, administration,
rangers, research, education, library, extension service for farms). Activities of each group
emerged from their duties imposed on the employment relationship (staff, administrators),
profits (farmers) or interest and knowledge (scientists and tourists). The main activities are
listed in the Table 1.

A central unit of the system consists of two computer servers: web server and database
server with configuration of Microsoft Windows Server, MS SQL Server, and ArcGIS Server
(Fig 2). There are two main applications working parallel on the web server: the first is a
geoportal which is working on Apache Tomcad, the second is ArcGIS web map services
supported by Internet Information Server.
The Biebrza National Park's Local Area Network (LAN) works in a domain managed by a
Microsoft Windows Server setup on second server - called Database Server or Repository.
All employees of the park have access to DSS resources in the reading mode. Writing mode
