One of the most powerful features of QGIS is its ability to clip shapefiles. This means that you can take one shapefile and use it to create a new, smaller shapefile that only includes the part of the original that you’re interested in. Clipping is especially useful when you’re working with large data sets and you only need a small portion of the data. For example, if you’re working with a state-wide dataset and you only need data for one county, you can use clipping to create a new shapefile that only includes the data for that county. Here’s how to clip data in QGIS:
1. Start by opening QGIS and loading the two shapefiles that you want to use for clipping. The first shapefile should be the one that you want to clip from, and the second should be the one that you want to use as your clip shape.
2. Next, select the “Clip” tool from the Vector menu. You’ll see two options for input layers – choose the layer that you want to clip from as your input layer, and choose the layer that you want to use as your clip shape as your clip layer.
