Exterior Parking Lot Lighting Design/Layout/Photometrics

Hello,

I am working on a lighting project for a parking lot. We need 2 layouts, same space but different wattage fixtures. The only layout I can provide is from Google earth, so measurements would need to be taken from there, measurements can be approx. I will provide IES file and where the poles are located with quantity of fixtures to be installed on each and height of poles. Let me know what other info is needed. The goal is to show overall lighting levels and be able to compare how much brighter the higher wattage fixture will be.

Thanks
