Working with vector data in QGIS

Now, let's have a look at how we can use QGIS for vector data management. Doing spatial data management in QGIS is not complicated and, once you master it, it's actually enjoyable to perform in QGIS. We'll learn about merging shapefiles, converting polygons into lines and vice versa, clipping, working with difference, buffers, working with intersection, statistical summaries of vector layers, using field calculators, and more.

Combining shapefiles

In many cases, we need to combine multiple shapefiles, for example, when we need to merge the shapefiles of two contiguous areas. We'll merge two contiguous districts in Bangladesh, Dhaka, and Gazipur. We have shapefiles for both...
