DivePort can display data as boundary maps, point maps, heat maps,
- Boundary maps use country, province, state, county, or postal code data. Predefined regions of the map are color-coded according to the data summarized over a region.
- Point maps use longitude and latitude coordinates to show data points. Summarized data concentration is shown using color or sizing of the data points.
- Heat maps use longitude and latitude coordinates to show data concentration using colors.
- Hexbin maps use longitude and latitude coordinates to show data concentration using colored hexagons.
- Line maps use longitude and latitude coordinates to show origin-destination data by drawing lines on a map.
NOTE: Column data that contains longitude and latitude coordinates must be formatted as <longitude> <latitude> and the dimension name must be longlat. For example:
Placing the pointer on a map opens a tooltip that shows details about the specific location and data value.
In DivePort 7.1(19) and later, point maps can be set to refresh data at a specified interval, resulting in a real-time view.
Map Portlet Base Layer
The map portlet base layer is the map itself. You can select one of the following sources for your base layer:
In addition, you can create your own custom GeoJSON file using a browser-based tool such as geojson.io. Each polygon in your custom geoJSON file must have a property that serves as a unique identifier for that polygon and the DivePort source data for the map must have a column that contains the polygon identifiers. Save your custom GeoJSON files in the \webdata\<diveport>\customizations\map-data folder to ensure that it appears as a geometry source in the edit map portlet wizard.
NOTE: The use of Thunderforest base layers requires a Thunderforest API key. For more information, go to:
The following maps are included in DivePort internally, and are available options as a geometry source in the map portlet configuration wizard:
- US Counties 20m (2010)
- US States 5m (2010)
- US Three Digit Zip Code Prefixes (2014).json
- US Zip Codes (Census Bureau 2014)
- World Countries 10m (Natural Earth)
- World Countries 50m (Natural Earth)
- World Countries 110m (Natural Earth)
- World States-Provinces 10m (Natural Earth)
- World States-Provinces 50m (Natural Earth - Canada and US only)

During an upgrade, in order for DivePort to be able to replace the map_data.dat file in the webdata directory, which is a local cache of map data downloaded from DiveLine, Tomcat must have permission to delete that file.
