Registration support plug-in using Leaflet. 
I made it to change from GMap, and to register easily from the management screen with the contents of 1 post 1 map. 
Corresponds to OpenStreetMap or Geographical map. 
A map is displayed on the management screen (POST, PAGE, custom post), so specify the location and zoom with the GUI operation. 
Geocoding is not implemented because there was no practical level service other than Google API.

Leafletを使った登録支援プラグインです。 
GMapからの乗り換えで、1投稿1地図のコンテンツで管理画面から簡単に登録するために作りました。 
OpenStreetMapまたは地理院地図に対応しています。 
管理画面（POST,PAGE,カスタム投稿）に地図が表示されますので、GUI操作で場所とズームを指定します。 
Geocodingは、Google API以外で実用レベルのサービスが無かったため、搭載していません。

Add short code [gmap] to insert in post a google map with advanced features (overlays, clusters, callbacks, events…) and place geolocalized post (with custom fields) in this map
To view post in map, you use this custom field : 
* geolocation : set here GPS coordinates for post 
* marker : set here url for marker icon. (optional)
To view map in a post, you use this short code ; 
[gmap width=w height=h border=b posttype=p taxonomy=t term=r maxpost=m centermap=c animate=a]
where 
* w,h are size of map (default is 500px and 300px) 
* b is css-like style for map border (default is brown solid line) 
* p is post-type (default is post) 
* r is a term for taxonomy t to filter post (default is all post, without taxonomy filter) 
* m is max number of post view in map 
* c il gps coordinates of centre of map 
* a is 0 for not animated marker, 1 for drop marker, 2 for bouncing marker
