Introduction
One of the reasons to use QGIS is its many features that enable management and analysis preparation of spatial data in a visual manner. This chapter focuses on common operations that users need to perform to get data ready for other uses, such as analysis, cartography, or input into other programs.
In this chapter, you will find recipes to manage vector as well as raster data. These recipes cover the handling of data from both file and database sources.
Joining layer data
We often get data in different formats and information spread over multiple files. Therefore, one important skill to know is how...
