SuperMap iServer supports publishing online Google Maps services (via Google Static Maps API) to local map services, such as WMS service, WMTS service, and REST map services, and supports storing the map tiles in the local. Before publish services, make sure you have a Client ID and a private cryptographic key for the Google Maps service.
You can publish service Google services by following these steps:
- On the Home page of Service Management -> Publish Service or the Services -> Service Management page, click Quickly Publish Service to enter the publishing wizard;
- When the select data source is "Google maps service", click Next;
- Configure the service data to be published, such as the digital signature with access to Google Maps, and the parameters for map display, including:
- Google Maps client ID: An account with access to Google Maps
- Google Maps CryptoKey: The private key for this account
- Language: The language used for the annotation in the map. Select "zh-cn" in Chinese and "en-us" in English
- Google maps width: The width (in pixels) of a tile each time it is requested from Google Maps. Because a single tile may have a Google watermark on it for each request, making the tile larger reduces the watermark density throughout the window. However, if a single tile is too large, it may affect the efficiency of tile acquisition, so you should set a reasonable value according to the hardware, software and network conditions.
- Google maps height: The width (in pixels) of a tile each time it is requested from Google Maps. Generally, the width and the height are generally set to the same.
- Select the published service type, such as rest map service, and click Next;
- Configure the service, and select enable cache for map tiles. When enabled, you can specify the storage type and location of tile data generated during map browsing (e.g. SMTiles, MongoDB, OTS, GDP), click Publish:
- After publishing, you can see the name and link of the currently published service. Click it to access the service directly.
After publishing, the service may not be able to plot normally due to network reasons. In this case, you can set the proxy for the provider. For detailed method, please refer to: configuring Google Maps map service provider through XML files.
