NHLSA Summer Seminar   
History and Development of Topographic Surveying, Isolines, and Contours
David A. Mann and Rick Ladd
Samuel E. Paul Community Center
61 South Street, Troy, NH  
The seminar is free, but limited to the first 100 NHLSA members. To ensure a seat, please register early!  
200 years ago, mapmakers could only draw a picture that represented a hill, possibly shading them to show some sense of an elevation change. David Mann will take us on a "time travel" from these early times up to his firsthand methods from the 90's. After a lunch break, Rick Ladd will whisk us ahead to modern times, showing how surfaces are prepared with CAD software. He will detail how to use the surface data available at GRANIT and Point Cloud information to create a state of the art plan.
This seminar is worth 2.0 CEU (subject to state-specific exclusions; seek clarification from appropriate state authorities).
