推荐不依赖互联网的嵌入式地图
我希望将映射映射控件(非常类似于 Google 地图或虚拟地球)嵌入到应用程序中,该应用程序在大多数情况下无法访问互联网,这意味着我无法使用上述 API 或 Google 地球。 地图必须驻留在本地计算机上。 我知道 MapInfo 在该领域是一个大牌,但有人知道那里有任何竞争对手吗?如果您使用这些工具实施了解决方案,您的体验如何?
I'm looking to embed a mapping a mapping control (very much like Google Maps or Virtual Earth) into an application that, in most cases, will not have access to the internet meaning that I can't use the aforementioned APIs or Google Earth. The maps would have to reside on the machine locally. I know that MapInfo is a big name in that space but does anyone know of any competitors out there and, if you've implemented a solution using these tools, what your experience was like?

ESRI 是另一家大公司,可能是最大的。 它们有 2 个 COM 组件:MapObjects 和 MapObjects LT。 后者做得较少,但免版税(即开发人员的费用,但不是每个席位的费用)。
ESRI are the other big company, probably the biggest. They have 2 COM components, MapObjects and MapObjects LT. The latter does less but is royalty free (i.e. costs for developers but not per seat).
微软有他们的Mappoint产品,尽管它需要安装在每个座位上,但这仅使其真正适合内部应用程序(并且也仅在Windows环境中)
Microsoft have their Mappoint product, although it is required to be installed on each seat, which only really makes it suitable for internal applications (and only in a Windows environment, too)
ESRI 在这一特定领域拥有丰富的专业知识。 看看他们的产品
ESRI have a lot of expertise in this particular field. Have a look at their product offerings
