hey Group:

I have been tasked with planning and performing a land survey to generate =
contours for a project. We will be using the Leica SR530 to collect point =
data to support the creation of 6" contours. The site may have as much as =
10' total elevation above sea level (it's near the Yucatan peninsula :))

What I need to know is how closely I need to plan my points to warrant 6" =
contours. From what I know of Lidar, you plan 2.5m postings to generate =
2' contours. If my math is correct, I will need to collect a posting =
every 2'.

Is this basically correct?
