Question

以下是仅显示一个多边形的链接。

https://www.google.com/fusiontables/embedviz?viz=MAP&q=select+col1+from+1PdVL8ltzXzHWbZI6MVWNghTz7sh9FKH9hw_YYYM+where+col0+%3D+412&h=false&lat=44.07068786477725&lng=-91.70146331134345&z=13&t=1&l=col1&y=2&tmplt=2

增加缩放将使形状首先消失，然后显示为不同的多边形。

这是几何coloumn的值：

有没有办法纠正这种行为？

看起来像FusionTablesLayer磁贴生成器的问题。如果我export it using the FusionTables API v1.0 and render it as a native Google Maps API v3 polygon，它似乎适用于所有缩放级别。

有两种选择：

你可以尝试扭转缠绕方向，这有助于一些像这样的奇怪案例
你可以尝试简化多边形（虽然对我来说似乎很简单），但这又有一些像这样的奇怪案例有帮助。

我在Fusion Tables User Group中讨论过我之前提及的实例，但是通过快速搜索无法找到它们。

这是one of the threads I was remembering
