Hi, In MI6.0, I have a point file with lat and long, and I can find the points' 'center' via SQL Select, specifying the following under Select Columns: WtAvg(lat, 1), WtAvg(long, 1) but I'm not sure what the 2nd argument should be. (I just tried '1' for kicks...) Also, I have a volumetric measure in a column in the points file that I'd like to use to skew the centroid towards points with high values in that column. Can the WtAvg do that? Thanks in advance for your time and patience! Erin Rubio Spatial Insights, Inc.
