Overview

When the user selects multiple objects in the map, these objects should be displayed in the Selection Panel both in AJAX viewer and Fusion viewer. We need to add a Selection Panel for AJAX viewer and enhance the Selection Panel for Fusion viewer.

Motivation

There are some use cases:

1.If several features are selected across different layers, the selection panel should allow users to easily visualize their attributes and which layers these selected features belong by;

2.At a given zoom level in a map, some features might be too close to each other for users to select them individually; users should be able to interact with the elements in the selection panel to help them narrow down a selection group to which feature he/she wants without changing the scale range;

3.The user selects multiple objects with the “Select Polygon”, and these objects will be displayed in the Selection Panel.

Proposed Solution

For Fusion viewer, we will use JxLib to enhance the UI of the Selection Panel. For AJAX viewer, we will also introduce the JxLib to create a Selection Panel same as the Selection Panel in Fusion viewer.
