WebJun 20, 2014 · implementing logic in your qgis plugin In our first example we would like to place some logic in the plugin: with the normal methods provided by QGIS it’s easy to create a buffer around a feature. But what, if you want several buffers that are equidistant from each other like 5 buffer zones in a distance of 10m? WebUnder the Processing Toolbox, search for the Buffer tool, double-click and add the roads layer as your Input Layer. Select a distance of 10 metres and keep the rest of the settings as they were. Click Run. Next, we will create an overlay to include the new road buffer with the multi-distance buffer we executed in the previous step.

WebThe Create Buffers tool uses a geodesic method for constructing buffers. Geodesic buffers account for the actual shape of the earth (an ellipsoid, or more properly, a geoid). Distances are calculated between two points on a curved surface (the geoid) as opposed to two points on a flat surface (the Cartesian plane). WebCreate a buffer around the road to find properties that fall within the buffer zone (see Abb. 10.14 ). For controlling protesting groups, the police want to establish a neutral zone to keep protesters at least 100 meters from a building.

WebCreate multiple buffer rings around a features/set of features. Creates "doughnut" ring buffers, not including the buffered feature, or regular buffers which do. Works in a sequential manner by buffering the resulting buffer and differencing the previous buffer. Also by default the buffer dissolves the features before buffering.
