Create an ArcGIS.com Web map using URL parameters

Summary

Instructions provided describe how to create an ArcGIS.com Web map using parameters within a URL.

Note:
This article has been superceded by ArcGIS.com online help. See the topic entitled Using URL Parameters for the latest information.

Procedure

Code:
http://www.arcgis.com/home/webmap/viewer.html?

Note:
To include more than one parameter, use an ampersand (&) to separate the parameters. For example:

Code:
http://www.arcgis.com/home/webmap/viewer.html?center=20,45&level=4

• Define the basemap used in the viewer.
  Set basemapUrl= to the map service. If a basemap is not defined, the default basemap will be the World Topo Basemap.
  
  
  Live Example
  

  Code:
  http://www.arcgis.com/home/webmap/viewer.html?
       basemapUrl=http://services.arcgisonline.com/ArcGIS/rest/services/World_Physical_Map/MapServer

  
  
  
  
• Define the operational layers that overlay the basemap.
  Use either webmap= or url=.
  
  
  The webmap parameter accepts the Item ID of a Web Map saved to ArcGIS.com.
  Live Example
  

  Code:
  http://www.arcgis.com/home/webmap/viewer.html?webmap=2def3f0c7be74f05af33ac87b8d03ef2.

  
  The url parameter accepts a single service URL.
  Live Example
  

  Code:
  http://www.arcgis.com/home/webmap/viewer.html?
       url=http://services.arcgisonline.com/ArcGIS/rest/services/Demographics/USA_Daytime_Population/MapServer

  
  
  
• Center the map at a particular location.
  Set center= using geographic coordinates (X,Y) or projected coordinates (X,Y,WKID).
  
  
  Geographic Coordinates
  Live Example
  

  Code:
  http://www.arcgis.com/home/webmap/viewer.html?center=20,45

  
  Projected Coordinates
  Live Example
  

  Code:
  http://www.arcgis.com/home/webmap/viewer.html?center=500000,5500000,102100
  

  
  
  
• Define the extent of the map.
  Use extent=. The extent parameter accepts geographic coordinates (GCS) as: MinX,MinY,MaxX,MaxY
  or projected coordinates (PCS) as: MinX,MinY,MaxX,MaxY,WKID.
  
  
  Geographic Coordinates
  Live Example
  

  Code:
  http://www.arcgis.com/home/webmap/viewer.html?extent=-117.20,34.055,-117.19,34.06

  
  Projected Coordinates
  Live Example
  

  Code:
  http://www.arcgis.com/home/webmap/viewer.html?extent=-13079253.954115,3959110.38566837,-12918205.318785,4086639.70193162,102113

  
  
  
• Define the scale level of the map viewer.
  Use the center parameter and level=. The level parameter accepts the LevelID of the cache scale as listed in the REST service endpoint.
  
  

  The cache scale level can be determined using the information on the Map Service's REST endpoint. The resolution is inversely related to the scale.
