map-viewer

Map viewer for Atom

an Atom package for visualizing and editing map.json files.

it uses leaflet and leaflet-map-builder.

How to use

Open a valid map.json file and lunch the viewer with Packages -> Map Viewer -> Open or with ctrl-alt-m.
Create an empty map.json with Packages -> Map Viewer -> New -> Map and manually add layers.
The map is updated every time the configuration file is saved.
Switch on/off layer control in package setting.

Adding layers

Some layer templates can be loaded from the context menu (right-click) on the editor or via keybindings: ctrl-alt-n followed by m (marker), p (polygon), l (polyline), t (tile layer), g (GeoJSON).

Similarly, you can activate drawing capabilities via ctrl-alt-v followed by p (polygon), l (polyline), .... Once drawing is done the skeleton of the layer configuration is available in the clipboard, just paste the text in the configuration file and save it to reload the map.

Minimal example

Copy paste the following map.json in your editor and lunch the map-viewer (e.g. with ctrl-alt-m).
