<p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial","sans-serif"'>I
use MapServer to overlay point data on shapefile layers using an ODBC OGR
connection. I’m writing to solicit ideas for how to best design a
geocoding error checking query. In addition to having the requisite latitudes
and longitudes, the ODBC data source also has client documented State/Province
names in full. What I hope to do is perform something like a FeatureQuery to
find all records within the ODBC data source whose documented State/Province
& latitude/longitude do not correspond to that in the shapefile (i.e. find
all database records whose latitude/longitude fall outside the client’s documented
State/Province). What I ultimately need to do is produce a recordset containing
these erroneous records…either the client documented State/Province is
wrong or (more likely) their documented latitude or longitude are wrong. In
either case, I need to spit these out for clients.<o:p></o:p></span></p>
