Re: VPF layer data

Hi Barb,

Are the other features showing up on the layer?

The vpf.paths property should indeed be pointing at the same directory
as the DescribeDB command.

Oh, you might have to add the coverage, 'util' from the power line entry
from DescribeDB:

lib_082:util:powerl: [edge feature] Power Transmission Lines

util is the coverage type, powerl is the feature type.

Add 'util' to the coverageType property list. The 'powerl' feature
should stay on the edge feature property list, just as you have it.

All coverages go on the one properties list, and the features are put on
their particular geometry list (text, edge, area).

Cheers,

Don
