Get Shape data from ShapeLayer

[Adam Brightwell]

I am currently using ShapeLayer to display shapefiles.  However, I need to access the data (coordinates) that make up a given shape within that layer.  Any suggestions on how this might be accomplished?

Thanks,
Adam

Hi Adam,

You can ask the ShapeLayer for its OMGraphicList, using getList().  
The OMGraphics contain the coordinates.  They will be in the  
OMGraphicList in the order they were retrieved from the Shape file.

For OMPoly objects, you can call getLatLonArray().  Beware!  When you  
get those coordinates, they will be in radians.  If you want to  
inspect them as lat/lon decimal degrees, you should make a copy of  
them before sending them to ProjMath.arrayRadToDeg(), which will do  
the conversion in place.  If you don't make the copy, you mess up the  
OMPoly.

Hope this helps,

Don

Excellent, I think this will work for me.

Thanks Don!
