To keep things simple – you will probably be working with two types of data: Vector and Raster.
- Points Lines and Polygons.
- Approximately 56 Vector Data Formats as of 3.4
- Including: Shapefile, DWG, ESRI File Based Geodatabases, CSV, and Geopackage
- Geopackage is the Default data format for QGIS 3.0
- 70+ File Formats
- Including: JPG, TIFF, GeoPackage Raster, WMTS, WMS PNG
- Cloud Optimized GeoTIFF
I haven’t really touched on Databases. My favorite database (and QGIS’s Favorite) is PostgreSQL/PostGIS. That’s a way longer conversation than this very short tutorial can provide.
Assuming you have some vector data, add it to QGIS (you can even drag and drop the data into QGIS). I’m going to add two layers.
Right click on your Vector Layer in the Layer Panel. Click on Properties.
From this point you can start changing how your vector data looks. If you click on the Simple Line/Simple Fill you can chage all sorts of aspects of the vector layer. From line widths to colors to symbols.
Below Symbology notice there is a place you can label your data also.
I’ve neglected to mention saving your QGIS Session. Save it to your hard drive. This saves all the changes you’ve made and stores your data in a QGZ file. You can delete the QGZ if you need to and all that will happen is you lose your changes – will not lose any data.
I changed a few things such as colors and labeling on my vector data and placed it over OpenStreetMap.
