Some Of My
Favourite QGIS Plugins

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

Export your project for use on a web page

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

Autotrace Snap points to layer features when digitising

CartoDB Import/export layers from/to CARTO

OSM Info Retrieve information about point from OpenStreetMap

Online Routing Mapper Find routes between points using online services
