I have been a GIS professional working on a wide range of problems for 10 years. Now I don`t do any GIS work any longer, so I don`t plan posting any answers. If you find any answer of mine useful to you, I`m so glad, it was worth the effort! I have maintained a personal blog about GIS which has a ton of useful posts but is now in read-only mode. There is one post I suggest reviewing to anyone in the GIS industry. It is the quintessence of all my findings: . Best of luck!
