QMapshaper
QGIS plugin to turn mapshaper into QGIS tool.
Installation
Requires installation of NodeJS, npm and mapshaper.
Linux
On most Linux distributions this should do:
sudo apt install nodejs
sudo apt install npm
npm install mapshaper
You can also install mapshaper globally for the system.
npm install -g mapshaper
Windows
On Windows the setup may vary. You then need the path to mapshaper folder in node_modules. See details below.
Setting up
In QGIS settings under Processing under QMapshaper the mapshaper folder needs to be set up.
On Linux this tends to be: /home/user_name/node_modules/mapshaper, where you just replace user_name with your user name. If this is not the case you have to investigate, where the folder is. Best way might be to search for file mapshaper-gui which is located in the mapshaper/bin directory.
Tools
So far there is processing tool Simplify vector usable in complex workflows. There is also Interactive Simplifier which is GUI tool that allows playing around interactively with the simplification parameters.
