使用 Bing 地图和 OpenStreetMap 进行免费 Silverlight 地图绘制？
我最近阅读了这篇文章。它使用 Silverlight Bing 地图控件显示来自 OpenStreetMap 的地图数据。在本文中，他扩展了 MapCore 并开发了一个真正的 OpenStreetMap 控件，该控件不再要求您使用 Bing API 密钥。
我的问题很简单。此解决方案是否构成商业项目的免费 Silverlight 地图，或者 Bing 地图控件的使用本身是否需要许可？
提前致谢。
I recently read this article. Which uses the Silverlight Bing maps control to display map data from OpenStreetMap. In this article he extends MapCore and develops a true OpenStreetMap control which no longer requires you to use the Bing API key.
My question is simple. Does this solution constitute free Silverlight mapping for commercial projects or does the use of the Bing map control itself require licensing?
Thanks in advance.

以下内容摘自 Microsoft Bing 地图使用条款 (http://www.microsoft.com /maps/product/terms.html），并强调：
“如果您想开发或托管旨在访问和使用该服务用于商业、非商业或政府用途的应用程序......并且您的应用程序和内容将不受限制地公开提供（例如，不需要登录或密码），您无需签订 MWS/BM 协议或通过 Microsoft 批量许可许可服务即可这样做通过遵守...所有关于教育和非营利用途的限制...以下限制也适用：
在任何 12 个月期间，您不得超过 125,000 次会话或 500,000 笔交易（两者均在 SDK 中定义） ”。
因此，即使对于商业项目，您也不需要拥有许可证，只要您遵守服务条款中规定的限制（完整的 ToS 中还规定了其他限制，包括不超过 50,000 个地理编码请求） 24 小时期间）。
但是，请注意，加载 Silverlight 控件本身（即使包含 OSM 数据）也算作一个事务（来自 http://msdn.microsoft.com/en-us/library/ff859477.aspx），因此，如果您每年的会话超过 125,000 次，则可能需要许可证。

Following excerpted from the Microsoft Bing Maps Terms of Use (http://www.microsoft.com/maps/product/terms.html), with emphasis added:
"If you would like to develop or host an Application that is designed to access and use the service for commercial, non-commercial or government use... and your Application and content will be available publically without restriction (for example, login or password must not be required) you may do so without entering into a MWS/BM agreement or licensing the service through Microsoft Volume Licensing by complying with... all of the restrictions on educational and non-profit use... the following restriction also applies:
You may not exceed more than 125,000 sessions or 500,000 transactions, both as defined in the SDKs, in any twelve month period."
So, you do not need to have a licence, even for commercial projects, so long as you abide by the limits set out in the terms of service (there are other limits stated in the full ToS, including no more than 50,000 geocoding requests in a 24 hour period).
However, be aware that loading the Silverlight control itself (even with OSM data) counts as a transaction (from http://msdn.microsoft.com/en-us/library/ff859477.aspx), so you might need a licence if you have more than 125,000 sessions a year.

即使您不使用 bing 磁贴，Bing 地图控件也需要许可证。看一下完全开源的 deepearth silverlight 地图控件，与 OSM 配合良好：

the bing maps control will require a license, even if you are not using the bing tiles. Take a look at the completely open source deepearth silverlight map control, works well with OSM:
