....visualisations is not within the scope of this thesis. Interactive Interfaces A dynamic visualisation interface can be used to aid in the comprehension of the information presented in a visualisation. Dynamic Queries and Filters are two ways of achieving such an interface. Dynamic Queries [1, 69] allow users to change parameters in a visualisation, with immediate updates to reflect the changes. This direct manipulation interface to queries can be seen as an adoption of the WYSIWYG (What you see is what you get) model, where a tight coupling between user action and displayed documents ....

The background for interfaces to EOSDIS is discussed further on the web at [6] 1. 2 What are Dynamic Queries Dynamic queries are an interface paradigm that allow the user to interactively control query parameters and generate a rapidly animated visual display of database search results [1, 2, 5, 7, 8, 10 13, 15, 16]. As users adjust sliders or buttons, results are updated nearly continuously on the display. Each adjustment to a slider and each button click is called a query. The answer to the query is presented graphically. Experimental results have shown that dynamic queries are a fast, effective, fun, and ....

Query previews show the contents of the data during the query formulation process.
