Key ideas in Mastering Maps with QGIS
- QGIS uses file paths to locate data
- GIS links visual shapes to underlying database information
- Moving source files breaks the link to the project
- Drawing programs only store visual coordinates, not spatial attributes
- The Layers panel controls the 'stack'
- The Browser is for file navigation
- Points should be on top of lines and polygons
- Identifying the primary functional areas of the QGIS interface
- Polygons at the top of the list will obscure smaller features beneath them
- The visual logic of the Layers Panel
- The .qgs/.qgz file only contains project settings
- The Pan tool moves the view
- The raw data files (e.g., GeoPackage, Shapefile) must be included with the project file
- The Pan tool is distinct from selection tools
- QGIS is a viewer/interface for data
- Layer symbology (colors/styles) is saved in the project
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Mastering Maps with QGIS the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
