Profile Wavelength/Height Calculations--not tested recently, and probably removed

Wavelength (km) Median: 2.53 Mean: 2.56 Std Dev: 0.94 Height (m) Median: 87.17 Mean: 75.32 Std Dev: 24.05

Several options:

• Right click on topographic profile; insure profile was correctly oriented to capture periodic structure (perpendicular to crests and troughs).  Adjust Parameters.
• From Fabric at point option on  Calculate,  Topographic Grain menu.  This calculates the direction of the fabric, draws a profile at right angles, and computes wavelength and height.

Option on LOS Right click:

• Draw a profile, perpendicular to the dune crests.
  • Peaks are determined by  parameters on Wavelength tab of Topographic fabric vector overlay form
• Pick option after LOS Right click
• For each point identified as a peak on the profile, the algorithm will find all points in both directions on the same crest
  • Spacing of points along the crest is currently hard-wired into the program at 500 m.
• The data will be in a series of CSV files in the temp directory, which will be collected into a single database..
