Client Actions SpatialIdentify

Provides a means of displaying attribute information relating to all of the entities that a user selects when clicking on the map.

Compared to the standard Identify action the Spatial Identify doesn't use the active entity as the source for the entities to display information about, but instead searches through every entity to find any that intersect the shape drawn by the user. Which means of course that it can take longer to display its information than the regular Identify action.

The Spatial Identify action always displays its information in a popup window.

Example

Default with labelled button

<item action="com.cohga.html.client.map.spatialIdentify">
        <label>Identify</label>
</item>

Change the default entity

<item action="com.cohga.html.client.map.spatialIdentify" defaultEntity="roads">
        <label>Identify</label>
</item>

Refine and alter the entities

<item action="com.cohga.html.client.map.spatialIdentify">
        <entity id="property" maxScale="12000"/>
        <entity id="road" isDefault="true"/>
        <entity id="suburb" minScale="25000"/>
</item>

Note that prior to Weave 2.5.18 there is a bug that stopped the following example from working, and from 2.5.18 on-ward the highlight section can be added to the map view anyway which allows it to be set once and applied to all the tools that highlight an entity so it doesn't need to be set for each tool individually.

Changing the highlight styles

<item action="com.cohga.html.client.map.spatialIdentify">
        <highlight>
                <marker>
                        <icon>resources/images/markers/w-marker-red.png</icon>
                        <width>24</width>
                        <height>30</height>
                        <offsetx>-8</offsetx>
                        <offsety>-28</offsety>
                </marker>
                <vector>
                        <strokeWidth>3</strokeWidth>
                        <strokeColor xsd:type="xsd:string">#d27316</strokeColor>
