Overview of Map Support

The WebFOCUS mapping architecture features two HTML5 map viewer engines, one from Environmental Systems Research Institute, Inc. (ESRI®) and one from Leaflet. Both of these engines use Esri map tiles as their base maps. They both also provide zoom, pan and scale controls with 19 levels of zoom detail.

• The Esri map viewer provides a more accurate geometry with richer symbolization than the Leaflet map viewer. Using the Esri map viewer, your charts can include demographic layers with data available on an Esri server (such as population density data) and feature layers that outline geographic areas on the map. It also provides a host of customization options through its API. However, the Esri viewer cannot be easily redirected in house, as the Leaflet map viewer can, if you encounter firewall or security policy issues. Also, not all of the Esri options are freely available. If you require services or data not available for free, you can license additional services or a local server from Esri.

  Esri HTML5 charts are only supported with WebFOCUS chart attribute syntax, described in WebFOCUS Chart Attribute Syntax.

• The map viewer from Leaflet includes a default mapping server supplied by Esri. You can easily import map tiles (bitmaps) from other mapping services such as Google™, and UrbanMaps©. For more information about supported map services and other supported features of the Leaflet engine, see http://leafletjs.com/.

  Leaflet HTML5 charts support both WebFOCUS chart attribute syntax and traditional WebFOCUS syntax. If you use the chart attribute syntax, the attribute categories are the same as for the Esri charts.

Like all HTML5 visualizations, the highlighted markers and regions on the maps support additional chart properties and WebFOCUS request features such as drill, multi-drill, and informational tooltips. Advanced users can configure the map server to add their own locations and map definitions, using GeoJSON and JavaScript files.
