This is a tool I am slowly building to both learn about web mapping tools, and to create a platform to make maps I am interested in.
It is written using AngularJS and the angular-leaflet-directive wrapper for leaflet.js.
If anyone is for some reason interested in trying this out locally, it is built and run with gulp.js, so just pull down the repo, npm install, and then run gulp. The app will be available at localhost:8000.
All files are edited in the src/ directory, and gulp will do its magic and put everything in public/ for consumption by the client.
Tests are run with karma start.
