The SDLS web pages are divided in three areas:
  1. The left-hand panel shows the system menu.
  2. The central panel shows query results, data, metadata and unstructured data.
  3. The right-hand panel shows forms for refining queries or lists of related data links
The system structure is concentric; this means that Areas contain Projects, that contain Lines, that contain Files. Within each level, cursor-sensitive links are provided in the left-hand menu panel to jump to a different level (marked in blue) or return you to a parent Line, Project or Area (marked in red). Certain common precomputed solutions are provided to speed up the system usage, but any specific query can be submitted, and, if no precomputed solution is available, your request will be processed on the fly. In this case a smart server-side caching utility will be activated to improve system performance. When metadata are too verbose they are hidden to avoid cluttering the page. In this case a [+] mark allows them to be shown in full. To hide them again click on the [-] mark.
The SDLS website is designed to use SVG vector graphics. SVG is a language for describing two-dimensional graphics and graphical applications in XML. It is an open standard created by the World Wide Web Consortium. In the SDLS website it allows the selection of seismic lines interactively from a geographic map. SVG support is native in some browsers (Firefox, Opera) but not all its features are available. THE SDLS website therefore uses the Batik SVG Toolkit to handle the SVG graphics thus making it accessible from any regular internet browser. The major browsers Explorer, Opera, Firfox, Chrome and Safari have all been tested.

Help on menu...
The system menu can be found on the left hand panel of the web pages. It is automatically updated to provide full access to the system functionalities and allows at any level (area, project...) to return to the above level or delve into a more specific selection.
Buttons
Resets all session parameters
Sends you back to the homepage where SDLS related issues are listed, preserving current session
Sends you one page backwards
Allows seismic lines to be selected from one of the SDLS designated areas.
  1. Select an area from the map of Antarctica
    • You can zoom, pan and select a seismic line simply by clicking on the relative track-line.
    • Alternatively, you can select the line fron the list presented in the right hand panel
  2. You are sent to the metadata page from where you can select the file you want to explore
Sends you to the area that contains the selected Project, Line or File
Allows seismic lines to be selected from a user-defined geographic box.
  1. Enter Longitude and Latitude min/max values and a map will be produced on the fly after your request
    • You can zoom, pan and select a seismic line simply by clicking on the relative track-line.
    • Alternatively, you can select the line fron the list presented in the right hand panel
  2. You are sent to the metadata page from where you can select the file you want to explore
Allows Projects to be selected using a textual query
  1. Select the field type (Project name, Comment...)
  2. Enter value (can be a substring, blank to retrieve all records)
  3. A multipage table is produced where you can select a project
  4. You are sent to a map of the project from where you can select the line you want to explore, either interactively or from the panel on the right.
The original list of results from your query propagates also in the following queries on the right hand panel
Sends you to the Project that contains the selected Line or File
Allows Lines to be selected using a textual query
  1. Select the field type (Line name, Project name...)
  2. Enter value (can be a substring, blank to retrieve all records)
  3. A multipage table is produced where you can select a line
  4. You are sent to the metadata page from where you can select the file you want to explore
The original list of results from your query propagates also in the following queries on the right hand panel
Sends you to the Line that contains the selected File
Allows Files to be selected using a textual query
  1. Select the Data type (Seismics, Navigations, Others like images or unstructured data)
  2. Select the field type (Line name etc...for seismic data only, it is possible also to query the reel headers text)
  3. Enter value (can be a substring, blank to retrieve all records)
  4. A multipage table is produced where you can select a line
  5. You are sent to the metadata page from where you can select the file you want to explore
