如果找不到该工具栏,可以通过点击菜单【视图】->【工具栏】,勾选【图层管理工具...在GIS中,图层(Layer)定义了空间数据在地图窗口中的显示机制,是地理空间数据的可视化表达。图层通常与具体的数据源关联,采用符号和标签等制图元素将空间数据绘制在地图中。 多个图层叠加得到内容丰富...
- able to 'zoom to' records (Belgium), but NO points visible/selectable - creating a tiny table with only id and geom column of 3 records: mapcanvas emtpy - export the loaded (but invisible) layer to a geopackage: points AND attributes VISIBLE! - loading the data in dbeaver: all data...
My current alternative solution is creating an additional symbology as a marker line with an arrow showing the line direction (so QGIS reads and processes the line direction). Now the labels overlap the arrow symbols. Steps to reproduce the issue Use a multine-line layer with features that can...

需要根据数据类型选择合适的符号化和渲染方式,今天我们来聊聊QGIS中的地图要素渲染。 要素渲染,是将图层中每个要素以正确的符号绘制到地图中,是以要素为单位的样式设计。与之相对应的概念是图层渲染(Layer rendering),是将... 问答精选 React app is not working in IE 11 browser...
You will notice that theData defined overridebutton next toStroke colorhas turned yellow - indicating than this property is controlled by an override. A single symbol rendering of the power plants layer is not very useful. It doesn’t convey much information except the locations of the power pl...
Here is a short tutorial using a zone layer for the Universal Transverse Mercator (UTM) projection system. Here is a simple map in QGIS showing a GIS data set that maps out the UTM zones but also has row information. Universal Transverse Mercator (UTM) is a coordinate system used to ...
The resulting layerroads_line_intersectionsnow has all intersections correctly identified. But it is still not perfect. Use theSelect features by Area tooland select any intersection. You will see that at each intersection there are few duplicate points from adjacent segments. If we use this layer...
