Overview
The Map is a tool for displaying documents and entities with geo data on a map. It displays documents and entities in both clusters and a heatmap. Custom KML layers can also be loaded (but Mapquest only supports a small subset of the KML language currently).
Using the Widget
The map displays the documents, entities and events from your query. By default, these elements are displayed as a heat map, based on geo tags. The documents are displayed on the map using the following legend:
| Icon | Description |
|---|---|
 | Geographic areas with the greatest concentration of documents are displayed in red. |
 | Geographic areas with a medium concentration of documents are displayed in green. |
 | Geographic areas with a low concentration of documents are displayed in blue. |
Workspace Filtering
You can use workspace filtering with the map widget, to view corresponding documents in other widgets (Doc. Viewer, Entity Significance etc.).
- Ensure that the Map widget and at least one other widget are visible on the workspace.
- Click on one of the icons representing a cluster of documents. The other visualizations are filtered, according to which document cluster is enabled.
Region Selection Mode
You can use Region Selection mode to easily adjust your query, based on the geo selection in the Map widget.
To use region selection mode
- From the map widget, click on the region selection icon.
- Click and drag the curser to encompass the geographic region of your choice.
- Select from one of the following options.
| Field | Description | Notes |
|---|---|---|
| Add region to query: | Filter query based on boundaries of selected zone. | |
| Set region as geo decay: | Elevate documents from selected geo region to the top of search results, without discounting all other returned documents in query. Graph will re-populate with results weighted in favour of geo decay selection parameters. | |
| Zoom to region: | Zoom the map to the selected region. | |
| Cancel region selection: | Cancels region selection. |
The map query and display properties are updated according to your selection.
Exporting to KML (Google Maps Visualization)
You can use the map widget to make an export to KML format. This enables you to easily view the map using the third party mapping tool of your choice
To export a KML for current query data:
- From the map widget, select the icon along the top row of the Map Widget
. - Select Export to kml.
- Enter a title, select location (Desktop), and save KML file.
- Open KML file in 3rd party Mapping tool of your choice (i.e. Google Earth).
