Dear PostGISers, I have a need to perform certain spatial analysis to develop a stored function on a Feature Class(FC) using pl/pgSQL. The FCs use a Shape field to store spatial data. How can I apply PostGIS functionality on these FCs, for example, obtain a list of road segments of a known segment? Do I have to turn the FCs into spatial tables? If yes, will there be any negative impact on regular ArcGIS functionality?
Your input will be much appreciated. Thank you! -- Yours sincerely, John Zhang
