Web enabled software tools for bathymetry data management

Web enabled tools have been developed with the following functionality referring to bathymetry data:
1. Description and presentation of the source data;
2. Presentation of isolines for interactively selected area dynamically calculated from the data stored in the database;
3. Presentation of bathymetry for the selected cross-sections calculated from the data stored in the database Possible comparison of information for the same cross-section and for selected years;
4. The reading of coordinates in different coordinate systems;
5. Calculation of sediment accretion/erosion in a selected period; and
6. Interactive 3D presentation of bathymetry for a given instant.

The portal with a three-tier architecture was developed using ASP.NET, which consisted of the following functional packages:
1. Oracle Spatial data reader module;
2. Data presentation module; and
3. DEM generation and analysis module.

Functionality of applications is offered to "thin clients" (e.g. standard Internet browser). This means that all the data analysis is carried out by a server, only the results are send by web to the client, which minimizes network traffic. All data is stored in the Oracle Spatial format, which meets requirements of OpenGIS Consortium.
