Interact with the map¶

图例¶

打开**主菜单**，展开图层列表以显示地图图例。

Turning on and off layers¶

Main menu ‣ long press on the layer ‣ check or uncheck show on map canvas

识别要素¶

Tap on a feature on the map to identify it. If several features are located where you tapped (either because there are multiple features really close one to another, or because several layers are overlapping), they will all be listed in the menu that opens on the right of the screen.

点击列表中的某个要素以访问其属性。

点击**左右箭头**滚动显示识别出的所有要素。
点击**居中按钮**使得选中的要素在地图上居中显示。
点击**编辑按钮**可以编辑选中要素的属性。
Scroll through the sub-menus to access all the attributes.

识别图层时的例外情况¶

通常情况下，不需要对所有的图层都进行查询。有些图层仅仅作为底图显示，这些图层的属性也不是关注的重点。

可以在QGIS桌面中管理图层列表，通过`项目 ‣ 项目属性 ‣ 识别图层`找到图层，取消其底图图层选项即可。

Measure tool¶

Open the Main menu --> tap the settings button --> Measure Tool
