The native QGIS importer creates separate layers for each folder within a KML/KMZ. If there are hundreds or thousands of layers, the import can be very slow, crash QGIS, or create an undesirable number of layers. This plugin only creates one point layer, one line layer, and one polygon ...

QGIS支持多种格式的矢量图层文件,如Shapefile(.shp)、GeoJSON、KML等。 设置图层属性(可选): 在对话框中,你还可以设置图层的名称、编码等属性。这些设置通常是可选的,但在处理非英文或特殊编码的数据时可能非常重要。 点击“添加”按钮: 选择好图层文件并设置好相关属性后,点击“添加”(Add)按钮。QGIS将开始加载...
KML(KeyholeMarkupLanguage)是一种基于XML的地理数据格式,主要用于GoogleEarth中。QGIS也支持KML文件的加载和保存。 2.2矢量数据操作 2.2.1创建矢量图层 在QGIS中,可以通过图形界面或PythonAPI创建矢量图层。 通过图形界面创建矢量图层: 点击菜单栏中的“图层”-“新建”-“新建矢量图层”,选择图层类型(点、线、面),设...

ArcGIS XML is not a valid data source for QGIS and so you can't import or export it. KML, a variety of XML, is. My thought is to use Python to parse your XML into KML(s) files. QGIS GDAL/OGR could convert that to whatever you like, for instance Spatialite or PostGIS. Share ...
