"Access to LDD"
? And someone to run it for you?
The "simple" question you just asked Mark will fill pages in reply. Here's the deal, if you don't know how to contour, don't try. This envolves building a surface, editing the surface and then generating the contoure. You point files have no descriptor so II don't know if there are any breaklines to deal with. The truth is that if this is wide open property, with no curbs, buildings, sidewalks, etc. you can hire this out much cheaper than buying LDD and learning how to use it. If you could send out a comma delimitered .asc file of the coordinates, and this is all open land, you can have it contoured for less than $50. If this is a plant site, with curbs, sidewalks, trees, ditches, ad nausium, then this could run several hundred dollars to farm out. But if you are not "fluent" in LDD and topographic mapping, then you are asking for trouble to take yhis project on.
