Some Of My
Favourite QGIS Plugins
Mark Owen
BATH: HACKED
Introduction to QGIS
Plugins are awesome
Simple to search, install & update
Range from simple to esoteric
Usually solve a problem someone else has had
If youre stuck look for a plugin
Dont be afraid to play with them
Manage & Install Plugins > Settings > Show also experimental plugins
This is a list of my favourite plugins the ones I use regularly, that are most helpful or create the best visualisations
MMQGIS
The QGIS Swiss army knife
Great for working with CSV spreadsheet files
Simplifies some tasks
Read more about how to use by googling MMQGIS & clicking first result
Generate basic animations
Combine layers & data
Create grids & buffers easily
Geocode, import & export
Find & select features
Clean up your data
QuickMapServices
Choose from dozens of online road & satellite base maps from Google, OpenStreetMap, Mapbox & more
Once installed, go to plugin Settings > More services > Get contributed pack to get expanded set of available maps
Table Manager
Rename, reorder & remove your data fields
Useful for exporting data-rich layers when youre not interested in everything, want to remove redundant identifiers or rename stupidly named fields
DB Manager
You can store geometry in a database like Spatialite (easy to set up) & PostGIS (harder to set up but worth it)
Find & preview whats in your databases
Perform custom queries for ultimate control
Core plugin but mentioning because of power
QConsolidate
Export your project using QConsolidate
Everything is now in one folder ready to share
Simple but very useful
qgis2web

Twiddle the options
OpenLayers works better than Leaflet
Some issues with layers not stored in shapefiles & layers with a large amount of geometry
Qgisthreejs
Convert layers with height & elevation data into 3D visualisations which you can view in a browser
Will make your computer fan work hard
Time Manager
Turn data with time series information into animations
Remember to turn off Time Manager when updating layer styles
Can be a bit pernickety about dates
Miscellany
Layer List Quickly add commonly used layers
Realcentroid Find central points for polygons that actually lie within the polygons, even if they are concave
Swap XY Swap X & Y co-ordinates for a layer if it is broken
Cartogram Distort maps so areas correspond to a value
