     1)  Download leaflet
     2)  Download Leaflet markercluster
     3)  Download Jquery

2) Download the CSV file and Import them in Pinpint Custom object.
     1)Download Lat Long Coordinate File

3) You have made three custom label and fill the value in them which I have explained above.

 Label 1:- FeatureCollection


1

{
   "type": "FeatureCollection",
   "features": [

   Label 2:- LatlongName

{
    "type": "Feature",
    "geometry": {
       "type": "Point",
       "coordinates":  [ longitude,latitude ]
    },
    "properties": {
    "LOCATION_STREET_NAME":"streetName",
    "Range":"RangeValue"
    }
  },
 
Lable 3:- last

        }
        
        FinalStr = String.join(stringListmiddle, ' ');        
        FinalStr = System.Label.FeatureCollection+FinalStr +System.Label.last;

Leaflet: Make a web map In Salesforce with Image Icon Legends



Before copy and Paste below Visualforce page code and Controller code make sure you have done
below things which I have detailed explained in my Previous blog.

1) Downloaded All thee and saved them in Static Resource
     1)  Download leaflet
     2)  Download Leaflet markercluster
     3)  Download Jquery

2) Download the CSV file and Import them in Pinpint Custom object.
     1)Download Lat Long Coordinate File

3) You have made three custom label and fill the value in them which I have explained above.

 Label 1:- FeatureCollection

{
   "type": "FeatureCollection",
   "features": [

   Label 2:- LatlongName

    },
    "properties": {
    "LOCATION_STREET_NAME":"streetName",
    "Range":"RangeValue"
    }
  },
 
Lable 3:- last

]
}

 4) Download Below Icons and save them in Static Resource . We will use as Custom Marker Icons .
    1)  GreenLeaf
    2)  YellowLeaf
    3)  Redleaf
    4)  Rat

Now if you have done all Four points above you are ready to go .You can now Copy and Paste below visualforce page and Controller code.

Leaflet: Make a web map In Salesforce with multiple Markers icon based on Range



Before copy and Paste below Visualforce page code and Controller code make sure you have done
below things which I have detailed explained in my Previous blog.

1) Downloaded All thee and saved them in Static Resource
     1)  Download leaflet
     2)  Download Leaflet markercluster
     3)  Download Jquery

2) Download the CSV file and Import them in Pinpint Custom object.
     1)Download Lat Long Coordinate File

3) You have made three custom label and fill the value in them which I have explained above.

 Label 1:- FeatureCollection


1
2

{
   "type": "FeatureCollection",
   "features": [

   Label 2:- LatlongName

    "type": "Feature",
    "geometry": {
       "type": "Point",
       "coordinates":  [ longitude,latitude ]
    },
    "properties": {
    "LOCATION_STREET_NAME":"streetName",
    "Range":"RangeValue"
    }
  },

}

 4) Download Below Icons and save them in Static Resource . We will use as Custom Marker Icons .
    1)  GreenLeaf
    2)  YellowLeaf
    3)  Redleaf
    4)  Rat

Now if you have done all Four points above you are ready to go .You can now Copy and Paste below visualforce page and Controller code.

Leaflet: Make a web map In Salesforce with multiple Markers icon based on range and Use of Fitbound



Before copy and Paste below Visualforce page code and Controller code make sure you have done
below things which I have detailed explained in my Previous blog.

1) Downloaded All thee and saved them in Static Resource
     1)  Download leaflet
     2)  Download Leaflet markercluster
     3)  Download Jquery

2) Download the CSV file and Import them in Pinpint Custom object.
     1)Download Lat Long Coordinate File

3) You have made three custom label and fill the value in them which I have explained above.

 Label 1:- FeatureCollection

}

 4) Download Below Icons and save them in Static Resource . We will use as Custom Marker Icons .
    1)  GreenLeaf
    2)  YellowLeaf
    3)  Redleaf
    4)  Rat

Now if you have done all Four points above you are ready to go .You can now Copy and Paste below visualforce page and Controller code.
