Visualisation products are used for presentation of EO information to the user. The user's interaction with the visualisations is predominantly viewing and interpretation of the informational content and arriving at decisions in the context of the user'S objective with the EO information. In addition, users of visualisation are all involved actors during image processing. For example, an EO analyst may use visualisations of EO data and preliminary EO products for getting a better understanding of the contained information and adapt his processing workflow to arrive ad improved results. Typical visualisation products include satellite maps, layouted digital maps, web visualisations in 2D and 3D, and analogue visualisation products.
A video is a structured file of 2D grids link by the time, is a regular file of values which has been processed to sensor units (e.g. calibrated). The result can be a single date acquisition or a combination of dates. For each point, the value represents a parameter imaged by the sensor. Videos of EO data present for example time series of satellite maps and other EO products (e.g. Arctic sea ice evolution in a time-series map video over the past 30 years).
