Aquarius Image Browser Module

• Wanted to provide a useful (and unique) image browser for our newly acquired Aquarius data.

• Previews images generated by the Tools and Services team at PO.DAAC had a specific directory structure.

• Versioning had to be considered.

• What’s a useful way to display the data? Ask a scientist!• Had several iterations of the UI.• Threw many UI designs at the team, eventually filtered to a

select few.

• Filtered capabilities• Calendar/radio buttons allow for filtering.• Animation on filtered selection.• Thumbnails integrated with animation viewer.• Larger image has Google Maps like zooming capability.

• How was it accomplished?• Two parts to the module• Back end service– Takes image type, start date, end date as parameters– Browses a local repository populated by our Tools and Services team (outside of

Drupal unfortunately). – Obtains most recent version available for selected dates.– Returns JSON response with available images and URL’s.

• Front end html/JavaScript– Generates backend request parameters through user selections.– Relies on the backend service to update images via AJAX.– Creates widgets and all interactive UI.
