Google地图TileProvider使用单个SVG地图 [英] Googlemaps TileProvider using a single SVG Map

问题描述

在我的Android应用程序中，我想要显示带有滚动和缩放功能的简单地图。我不想依赖网络连接的地图，所以一切都必须随应用程序一起提供。

我有一个想要显示的国家/地区的单个SVG文件（只有地块和/或水对我来说很重要）。我认为显示地图的最佳方式是使用自定义 TileProvider 的Google Maps View，它可以从SVG文件动态地生成切片。

然而，似乎我需要做数学运算，以某种方式映射实际坐标（ x 和 y 我将 TileProvider ）加入到SVG的scale中，这听起来像是一件不平凡的事情。

是否有其他选项我没有想到，这不涉及使用我的应用程序传送兆字节的磁贴？是否有可能为我提供这些东西的现有库？我应该使用一种完全不同的方法吗？

解决方案

希望它不会太晚=）

其实我找到了2个解决方案：

• 你可以使用这个库： SVGMapView

第二种解决方案由Google在应用程序中开发：

In my Android application, I want to display a simple Map with scrolling and zooming capabilities. I don't want to rely on network connection for the map, so everything has to be shipped with the application.

I have a single SVG file of the country I want to show (only land mass and/or water is important for me). I figured that the best way to display the map would be a Google Maps View with a custom TileProvider, that generates the tiles dynamically from the SVG file.

However, it seems as if I would need to do the math, that somehow maps real coordinates (the x and y I am getting in the TileProvider) onto the SVG scale, myself, which sounds like a non-trivial thing to do.

Is there any other option I didn't think of that does not involve shipping megabytes of tiles with my app? Are there maybe existing libraries that do the stuff for me? Should I use a completely different approach?

解决方案

Hope that it's not too late =)

Actually i found 2 solutions :

• You can use this library : SVGMapView

• The 2nd solution was developed by Google in the Application :
