In this chapter, we will be creating GIS data. We will predominantly be working with GeoPackages. This is the default format for storing GIS data in QGIS 3.4. Instead of the many extensions that a Shapefile has, a GeoPackage can have hundreds of layers contained in one file, making it simpler to share and manage.
We will look at creating geometries of points, lines, and polygons. We will add attributes to a attribute table and use the Field Calculator to calculate the area of a polygon. We will briefly discuss the use of scratch layers and exporting our data to a Shapefile. Finally, we will look at how raster data is imported into a GeoPackage.
In this chapter, you will learn about the following topics:
- Creating a GeoPackage
- Creating vector data:
- Editing geometry
- Creating attributes
- Scratch layers and saving as a Shapefile
- Working with raster data in a GeoPackage...
