In SuperMap iPortal, the DataViz WebApp provides the functions of address matching and POI (point of interest) search. Before using the DataViz WebApp to create a map, the administrator needs to perform service settings to activate the functions of address matching and POI search.

Log into iPortal with your administrator account, click Home>Management > Site Configuration > Apps Configuration >DataViz to enter the DataViz Setting page, click the "Service Setting" tab:

Address matching service setting

When using the file upload method to add a layer in the DataViz WebApp, if the location information is expressed by the address in the source file, the city range and address description can be parsed through the address matching service or the geocoding service to return the corresponding geographic coordinates and structured detailed description of the address.

Before using the address matching function, the administrator needs to add the address matching service address or geocoding service key in the "Service Setting" tab:

• SuperMap iServer Address Matching Service: Fill in the address of the address matching service in SuperMap iServer, for example: http://127.0.0.1 :8090/iserver/services/addressmatch-Address/restjsr/v1/address
• SuperMap Online Geocoding Service: Fill in the Key of the geocoding service. It should be noted that you must carry the Key to call the geocoding service REST API. The application address is: https://www.supermapol.com/web/mycontent/keys/register

After filling in, click the "Save" button.

Search service setting

The POI search control of DataViz WebApp provides the ability to query POI information.

Before using the POI search function, the administrator needs to set the search service provider in the "Service Setting" tab, and fill in the address or key of the search service:

• SuperMap iServer REST Data Service: Fill in the address and query fields of the SuperMap iServer REST data service (separated by commas). Example of the REST data service address: http://127.0.0.1:8090/iserver/services/data-changchun/rest/data/datasources/Changchun/datasets/Hospital
• SuperMap Onine Local Search Service: Fill in the Key of SuperMap Online local search service. It should be noted that you must carry the Key to call the local search service REST API. Application address: https://www.supermapol.com/web/mycontent/keys/register
