Chapter 3. Data Creation and Editing
In this chapter, we will first create some new vector layers and explain how to select features and take measurements. We will then continue with editing feature geometries and attributes. After that, we will reproject vector and raster data and convert between different file formats. We will also discuss how to join data from text files and spreadsheets to our spatial data and how to use temporary scratch layers for quick editing work. Moreover, we will take a look at common geometry topology issues and how to detect and fix them, before we end this chapter on how to add data to spatial databases.
