Well, at least you can find out how many points are on top of one or several other points:
In SQL Select: Columns: LAT, LONG, LAT + "#" LONG "LAT_LONG", Count(*) "NUMPOINTS" >From Tables: MYTABLE Group By: LAT, LONG Order By: NUMPOINTS Desc Now you get a grouped list of all the different LAT and LONG Values with the one that have many points at the same place at the top. To select these points, enter the following in SQL Select Columns: * >From Tables: MYTABLE Where: (LAT + "#" LONG) In (Select LAT_LONG From Selection Where NUMPOINTS > 1) HTH, Peter Horsb�ll M�ller GIS Developer Geographical Information & IT COWI A/S Odensevej 95 DK-5260 Odense S.

I wanted to select all records where the lat of 1st record = lat of 2nd record AND lon of 1st record = lon of 2nd record. I'm trying to identify where and how many points are right on top of each other and if they need to be dispersed or better geocoding. The table has about 30,000 points and I'm using MIPro 6.5.
