Overview

Some customers wish we could make it easier for users to select one or more features that– within a given scale range – might be overlapping or too close to each other. We will introduce a new widget "Feature Inspector panel" for both Fusion viewer and Ajax viewer. With this new panel, the user can distinguish the feature(s) which he/she wants.

Motivation

The current way to select features in MapGuide applications makes the process of distinguishing one specific feature out of a selection group difficult:

1. No means to visualize the attributes of multiple features at once;

2. No means to “browse through” a selection set;

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

This is the UI of this new widget:
