I have a list of corner coords for study areas in a sharepoint list. I used 'calculated field' to generate a url that launches our internal webmap in a new window and sets the extents as the coordinate corners. Client has asked for a bounding box to be drawn on launch.
I can change the structure of the url if required, but here is the current one - just using default parameters - http://www.arcgis.com/home/webmap/viewer.html?extent=121,-25,122,-24&mapOnly=true
The extent values are what should be shown as the polygon.
Can anyone assist?
We are not able to integrate the ESRI Maps for Sharepoint Web Part, (which I believe only does points anyway) - so please view sharepoint as only the method of generating the concatenated URL - not as the platform for development.
So it looks like a combination of a URL constructed to apply specific parameters for each corner point,
use ESRI urlToObject to extract the values
create polygon graphic using the values from above
