I was looking for a command to take region objects and convert them to Point or Symbols. I found the solution on the MapInfo Products Knowledge Base. I do not know what I am doing wrong but I get the message "Numeric Values required" This is what I am typing in:
update RushCreek-LV-Poole-Poles-UTMz11 set obj = createpoint(centroidX(obj), centroidY(obj)) Below is a copy of the write up on the the MapInfo Products Knowledge Base What am I doing Wrong? Product: MapInfo Version: 4.x\5.x\6.x Platform: Not Platform Related Category: Table Operations Summary: Converting table of region objects to a table of points. Question: How can a table of points be created from a table of region objects for use in a thematic map? Answer: Start with a copy of the region objects table as the region objects will be removed by converting them to points. After copying, open up the copy of the table and display the MapBasic Window. Type in the following command and press enter: update <tablename> set obj = createpoint(centroidX(obj), centroidY(obj)) This will now convert the regions to their geographic centroids (points) which can be saved and used as a point table for thematic mapping, etc. Last Modified: 03/30/2001 10:30:57 AM Gary W.
