As we noted in Chapter 1, Getting Started with QGIS 3, and Chapter 2, Loading Data, the default export GIS format in QGIS 3.4 is a GeoPackage. Any vector data operation that we perform can be applied to a Shapefile—at the end of this chapter, we will show how to export any vector layer in a GeoPackage into a Shapefile (you can also export to a number of other formats; see https://www.gdal.org/ogr_formats.html).
Open the QGIS project we created in Chapter 2, Loading Data. If you skipped the previous chapter, load the following layers from the GeoPackage associated with this book (available at this link): https://github.com/PacktPublishing/QGIS-Quick-Start Guide/blob/master/Alaska_GeoPackage.zip:
- Airports
- majrivers
- trees
Also load SR_50M_alasja_nad.tif from QGIS_sample_data (downloaded from https://qgis.org/downloads/data/qgis_sample_data.zip). Save this...
