kmlwritepolygon(filename,latitude,longitude) writes the geographic latitude and longitude data that define polygon vertices to the file specified by filename in Keyhole Markup Language (KML) format. kmlwritepolygon creates a KML Placemark element for each polygon. By default, kmlwritepolygon sets th...
kml知道应该添加一个多边形,并且它具有正确的颜色、宽度和描述,但是每当我缩放到该位置时,它都会将我带到坐标0,0,但没有多边形。我创建多边形的代码如下所示: pol = kml.newpolygon(name=pnt.name) pol.description = ("A buffer for " + pnt.name) pol.innerboundaryis = [newCoord] pol.style.linestyle....
以下是一个样式的示例 ("transBluePoly"),它定义多边形面为透明蓝色,多边形边缘线宽 1.5,使用默认的白色。Google 园区 41 号楼的示例会使用该样式(在 Polygons 文件夹中): <?xml version="1.0" encoding="UTF-8"?> <kml xmlns="http://earth.google.com/kml/2.2"> <Document> <Style id="transBluePoly...
This MATLAB function writes the geographic point, line, or polygon data stored in S to the file specified by filename in Keyhole Markup Language (KML) format.

A value of 0 sets no extrusion, while -1 creates an extrusion effect. Extrusion of features makes polygons look like blocks with their sides continuing down from the polygon into the earth's surface. The green polygons on the left (OID 3 and 4) of the following image are features withou...
Keyhole Markup Language (KML) is an XML-based format that describes geographic entities. Developed and popularized for use with Google Earth, the KML specification is now maintained by the Open Geospatial Consortium (OGC). KML can be used to draw features such as points, lines, and polygons ...
