<p style="margin-bottom: 0in"><font face="Arial">I digitized a poly
line into a
shapefile that represents a water feature. I used Vector/Extract
Nodes to create a point shapefile. I added fields to the
attribute
table with longitude and latitude of each point with the Field
Calculator. I imported the attribute table into an MS Access
database and used the Find Duplicates query wizard to find 11
pairs
of duplicate points in 2052 total points. The points are needed
for
use with the Google Maps API. </font></p>

Vector/Topology Checker
plug-in with a “must not have duplicates” rule to find the
duplicate points and received a “0 errors were found” message. </font></p>
