Re: [OpenMap Users] merging shape files

Hi Rachel,

You might want to look at the com.bbn.openmap.layer.ScaleFilterLayer,
which changes which layers are active based on scale.

You could also look at the com.bbn.openmap.layer.shape.MultiShapeLayer
to display more than one shape file at a time.

Lastly, you could use the components in the
com.bbn.openmap.dataAccess.shape package to read in each shape file,
get the OMGraphics for them, combine them, and then write them out into
a single file. You'd have to manage the dbf file contents in the same
way using the DbfTabelModel, taking care to make sure that the order of
the merged OMGraphics matched the order of the merged DbfTableModel
contents (as well as the data fields, which may not match).

Hope this helps,

Don
