Using Filters in Exploration

This workflow will explain the different filters which exist. These filters also apply on the workspace and the exploration view.

1. Access the filters​

Filters can be accessed through the filter icon on the layer panel.

2. The filters explained​

There are numerous fields which a user can build a filter.

Search - This works on the file name. If you have renamed a file you can search for it here. Alternatively, you can also filter for spcific text within the file name.

Acquisition date - If your data has an acquisition date you can search for it using the acquisition date range.

Source data type - this searches against the source data type, such as raster, or even more specific such as SAR

Categories - If you know an AI model has run on your data, you can search for you data using the specific category of the prediction. For example, if I run an aircraft model which has detected an A380, you can select A380 from this list and only files containing A380 will be displayed.

Resolution - With this you can select a specific spatial resolution range you want to filter. It is a step filter, giving specific steps on this range.

3. Viewport vs AOI​

The next filter set is regarding the area of interest. By default, the filter is set to viewport only.

Viewport - This will use the geographic bounds which are currently in view on the screen as a filter. Note - if any part of the horizon of the globe is showing, or the view angle is tilted, the system may register this as a global viewport and all data will show.

AOI - The next few filters are regarding an area of interest. It allows for a bounding box, or a polygon. We also allow for a point search. Any files which intersect with the point will be shown in the list.

The last option allows a user to turn off filtering by geospatial bounds, at which point all data will show regardless of zoom level (unless other filters are applied).

4. Properties Filter​

As a more advanced filter, it is possible to configure a filter by specific properties. It is vital that the user knows the properties of the file that the user is searching for.
