3. Database Correlation with GIS Environment and Visualization of Data

[8]  The universal and popular data format used for digital processing in various GIS systems is a shape format, including a set of separate shape files. The format contains descriptions of point, vector and polygonal objects. Each type of similar objects has a separate set of shape files. These three types of spatial objects are examined by GIS systems. The database "Carbonatites and Diamondiferous Kimberlite Massifs of the World'' contains the data on point objects. At the present time the scheme of correlation between the GIS system and the database, shown in Figure 1, is developed. The scheme is efficient and easy to use, when it is necessary to update the tables containing data on point objects, because, in the first place, editing of such tables in Microsoft Excel is easy and, secondly, the data in GIS are automatically updated.

[9]  The program ESRI ArcGIS 9.0. serves as GIS environment. The program ESRI ArcMap 9.0 is used directly for transmitting data, kept in the database. Besides visualization, the program allows to analyze and process data by multiple embedded methods and additional modules, developed and downloaded by a user (for example, a cluster analysis of spatial data based on artificial intelligence methods).

[10]  The GIS projects, developed in ArcMap 9.0, comprises the following layers of objects given in geographical projection:

  1. "Lines'': map margin, continental margin, land border of a province; sea border of a province;

  2. "State borders'';

  3. "Provinces'' (9 provinces);

  4. "Carbonatites'' (data from table tabl_karb);

  5. "Kimberlites'' (data from table tabl_kimb);

[11]  Descriptions of the layers of objects form a legend. Its fragment is shown in Figure 2, examples of visualization of the layers of objects are given in Figure 3. The program provides an opportunity for a user to choose any of the visualized objects on a map and obtain the complete data from the database, and also use different variants of search of objects. An example of obtaining data on an object, selected by a user, is shown in Figure 4, an example of a search of objects according to the given parameters is shown in Figure 5. Other layers of objects, available in shape-format, or GIS servers in the Internet (Figure 6) can be added and visualized. In the second case they can be downloaded with the WMS (Web Map Service) or WFS (Web Feature Service) protocols.
