Hello list,

I have a column in a table defined as a LINESTRING, the lines display just fine using mapserver. Now I want to create a line that is perpendicular to that line, but I want to do it with SQL. I can get the end point of the line, but I'm at a loss of what to do next. My goal is to create a T with the line that is already stored in the db. What is the quickest way to do something like this.

Thanks in advance,
