Description of Subsystems

Up one level

2. DESCRIPTION OF SUBSYSTEMS

 

2.1. The Navigation Subsystem (Fig. 2.1) is the basis of the Resources and Use of Water Bodies geoinformation database. This subsystem allows the user to select and view the system’s information nodes.

 

Initially, when the subsystem is started, the information node presents information on the Russian Federation as a whole. Further information display is determined dynamically depending on what actions the user selects.

Each information node is a crossing of an administrative object and a basin object in accordance with their hierarchical nesting.

 

Window work space of the Navigation Subsystem consists of three main panels:

- Toolbar,

- Request panel,

- Response panel.

 

2.1.1. The toolbar is located in the upper part of the subsystem's window work space (Fig. 2.2). It allows performing the Navigation Subsystem’s main commands.

Fig. 2.2. Overall view of the toolbar

Brief descriptions of the toolbar’s commands are presented below.

 

1.   – Go back one step of selecting information nodes. This command cannot be performed if the active information node is the subsystem’s first node.

2.  – Go to the first page. This command activates the subsystem’s first information node (information on the Russian Federation as a whole).

3.  – Display detailed information about the selected node. If a detailed information handler is registered for the selected information node, this command invokes the handler. In the database’s beta version, a detailed information handler is registered only for the Dnipro basin node.

4.  – Display the list of saved maps and diagrams. During work, the user can save maps and diagrams in a special storage. Information from the saved object storage is used when exporting data to Microsoft Word (see Report Subsystem below).

5.  – Start the Report Subsystem (see below). This subsystem is used to export information from the geoinformation system to Microsoft Word.

6.  – Print information. This capability is not available in the system’s beta version. To print data, the user can export information to Microsoft Word and then print the information so exported using Microsoft Word.

7.  – Brief information about the system.

8.  – Geoinformation database help. This capability is not available in the system’s beta version.

 

2.1.2. The request panel enables the user to select an information node (Fig. 2.3).

 

Fig. 2.5. Saving node information in the object storage

 Saved information is moved to a special object storage that can be accessed by clicking on the button on the toolbar (Fig. 2.6). Information from the saved object storage is used when exporting data to Microsoft Word (see Item 2.3 “Report Subsystem”).

Figures 2.7 – 2.15 give examples of working with the Navigation Subsystem.

When an information node that has a detailed information handler is selected, the appearance of the request panel changes (Fig. 2.15).

2.3. The Report Subsystem is used to export prepared information from the object storage (see Item 2.1.4) to Microsoft Word. The subsystem is started by clicking on the button “Export to Microsoft Word” on the main toolbar (Fig. 2.33).

                                      

Fig. 2.33. Start of the Report Subsystem

The subsystem initiates a connection with Microsoft Word’s OLE server, creates a new document using a template, and transfers the prepared data (text, diagrams, maps) into the created Microsoft Word document (Fig. 2.34).

Water Use in the Desna Basin in 2002

 

The Desna basin consists of four sub-basins (Fig. 1).

 

Fig. 1. The Desna’s sub-basins

Extraction from surface water objects in the Desna basin in 2002 amounted to 263.2 million m³. Extraction by subjects of the Russian Federation is presented on Fig. 2.
