This page was designed to provide an interface between the users and a Spatial database. Through this page users can retrieve all datatypes (Ocean Temperature, Ozone, Simulated SeaWiFS data) currently storaged in the database, as well as, their satellites, instruments, observational program (frequency, dates) and bitmap image files.
These are basic steps that you should follow to successfully run this interactive Java based system that allows you to manipulate and display Ocean Temperature, Ozone, and Simulated SeaWiFS Data:

• On the applet window, click on the Open Icon that is on the top bar menu. A schema of the database will be displayed on the window.
  
  
• Double click on the Category DataType. A new window will appear with some text boxes and buttons. Then you have two choices: enter data on the text boxes and click on Query or just click on Query to display the data. Once, data is displayed, you can click on any of the buttons ( Next, Previous) to browse the information on the database.
  
  
• Having selected a datatype, double click on the relation Takeby on the applet schema window. Another window will appear with a list of all available Satellites, Select one.
  
  
• Next, double click on the relation uses. A window will appear with a list of all available instruments, Select one.
  
  
• Then, double click on the relation progused . A window will appear with some text boxes and buttons. Then you have two choices: enter data on the text boxes and click on Query or just click on Query to display all observational programs. Once data is displayed, you can use the buttons ( Next, Previous) to browse the information on the database.
  
  
• Once you select an Observational Program, click on the relation hasdata , and a window will be opened with the bitmap file of the data that you selected. This window has a top bar menu from which users can select several actions to be performed on the data file.
