OIC. I don't think you can accomplish that with the GUI. A node has
multiple street segments coming into it, so there isn't a single value
to tag. Your typical case of two streets intersecting involves four
street segments (street x eastbound, street x westbound, street y
northbound, street y southbound); a more complex intersection could have
even more. The GUI could probably be tricked into giving you one street
[step 1: tag each node with the nearest street; step 2: tag centroid
with street value from nearest node], but you need more than that.
The GISDK can do this, however: GetNodeLinks() will yield an array with
the IDs of all of the street segments that intersect with that node.

Thanks Moshe.
Actually, I did a select by location and got all the the nodes for the
closest instesection to my centroid layer. My endpoint node layer for
my streets (not caliper streets), however, has only the latt/long
as attributes. What I need is the names of the all the streets that
intersect where the node lies, not just the latt/long. I need to put
these names from the street layer in my node dataview somehow. Does
this make sense? Maybe I'm just missing something simple?

Perhaps I'm missing something here, but can't you just tag your
centroid layer with the nearest node? If you're using the Caliper
streets file, I'm referring to the the layer na! med "CDF node
layer" that is hidden by default-- it has a point for every
intersection.
Type "tagging" into Maptitude help for more info about this
operation-- it behaves slightly differently depending on whether
you are using point, line, or polygon layers.

Hi,
I have a centroid point layer and want to overlay this with my
street layer in order to select the nearest intersection to the
centroid point. Is there a way to do this in Maptitude 4.8
outside of GISDK? I'm not much of a coder, so I was hoping to
find a way to due this with existing features of Maptitude. Any
advice is appreciated!
Thanks
Bob
