D. Douglas' Manual Classification Tools: Documentation - Douglas segmentation algorithm

Greetings, In reply to Roland's questions, the attached Excel file contains a series of worksheets that decompose and document each step of my segmentation algorithm. Daily tracking data for bar-tailed godwit "H3" are used to illustrate, step-by-step, the variables, calculations, and conditional tests involved. "H3" is the same track that was used to generate the grahics in the PDF file I posted recently, which also contains a Google Earth rendition of "H3's" daily data. Perhaps someone would feel inspired to port the logic to R, so more of you could experiment with your own data, comment, and improve the algorithm if warranted.

nice breakdown

Thanks David - this is a nice, logical, description of your tool.
Roland
