KML反转国家边界 [英] KML invert country border

问题描述

我需要将波兰国家/地区的KML文件转换为波兰文. 我需要在其他国家/地区覆盖白色，只有波兰应该可见. http://cv.bluewolf.pl/kml-map/ 我在转换边界时遇到问题，并将白色覆盖层放置在世界其他地方.应该只有一个国家(波兰)可见.

I need invert KML file with Poland country. I need white overlay on other countries, only Poland should be visible. http://cv.bluewolf.pl/kml-map/ I have a problem with converting borders, and place white overlay on the rest of the world. Only one country (Poland) should be visible.

我尝试使用geocodezip中的KML绕线反转工具，但找不到任何教程或文档. 我从github尝试了Mask-KML-polygons来转换KML文件，但这不起作用.

I tried use KML winding reversal tool from geocodezip but i can't find any tutorial or documentation. I tried Mask-KML-polygons from github to transform KML file but this don't work.

Somone可以告诉我如何使用才能在地图上获得这种效果? http://www.geocodezip.com/geoxml3_test/v3_geoxml3_NetherlandsInverted.html

Somone could tell me what can I use to get this effect on map? http://www.geocodezip.com/geoxml3_test/v3_geoxml3_NetherlandsInverted.html

推荐答案

根据

According to the winding reversal tool, all the polygons in POL_adm0.kml wind in the negative direction.

您要做的就是添加一个相反方向缠绕的outerBoundaryIs，并将所有现有的outerBoundaryIs标签更改为innerBoundaryIs标签.这是一个<outerBoundaryIs>，其绕向正确的方向:

All you need to do is add an outerBoundaryIs that winds in the opposite direction and change all the existing outerBoundaryIs tags to innerBoundaryIs tags. Here is an <outerBoundaryIs> that winds in the correct direction:

<outerBoundaryIs><LinearRing><coordinates>
180,85 90,85 0,85 -90,85 -180,85 -180,0 -180,-85 -90,-85 0,-85 90,-85 180,-85 180,0 180,85 
</coordinates></LinearRing></outerBoundaryIs>

注意:它适用于本机Google Maps Polygons(在geoxml3中)，但不适用于 KmlLayer .

Note: It works with native Google Maps Polygons (in geoxml3), but not with KmlLayer.
