Brochures & Information

GDADS —Enables archiving and Internet distribution of large spatial data .

Summary

GDADS aims to provide an easy-to-use, fully web-enabled solution to the problem of both archiving and Internet distribution of a wide array of large size spatial data.

By combining existing relational database technology and Java applications and applets GDADS is able to deliver display of complicated meta data spread over many database tables, located scaled, data images and reliable data archiving solutions tailored to individual customers needs.

Features

• Fully functional 100% Java application suite with web-enabled client interfaces.
• Uses relational database technology to store and broadcast an extensive range of meta-data (information used to describe the archived data).
• Supports all major database systems that have Java DataBase Connectivity (JDBC) drivers. This includes Oracle, Sybase, MS Access, Ms SQL Server, PostGresSQL and others.
• The system is extensible and easily tailored to suit most end user needs.
• The current examples are Australian Gravity data centered around Queensland and Botswana geophysics data (Now out of date to JDBC updates).
• Both these data sets are being served using POSTGRESS. We have found this to be 5 to 10 times slower at serving queries over the net than ORACLE.
• The vector and GIS content is being served by ARCShape files and the images via JPEG.

Distribution

• Advertising on a map based scheme through the Internet.
• FTP delivery possible.
• Internet ordering system with e-mail confirmation.
• Internet or Intranet systems available.

Archiving

• Underlying database of your choice.
• Extensive selection of archive media.
• JDBC/ODBC compatible.

Product description

The GDADS system is divided into client and administration sub-components.

Client components

The client component consists of:

• A map-based interface
• A list-based interface

Both are platform independent, web deployed Java Applets which allow:

• Controlled viewing of meta data
• Over the net ordering of particular data sets
• (In an intranet environment) FTP distribution of data

The map based client also permits viewing of geo-located, scaled images of the data, plus querying based on the data type and location (based on standard sheets).

Administration component

The database and archive administration management component consists of two applications that are local workstation based:

• The archive/retrieve tool allows data to be transferred between local hard disc storage and various off-line storage and distribution media such as magnetic tape, CD-ROM and DVD.
• The database tool permits the GDADS administrator to access the database management system and perform a wide array of database functions, such as:
• Table creation and removal
• Table record entry
• Record update and record delete
This tool is database independent and performs the same function with the same interface for all supported databases.
