Title: Skyline Analsis with SkylineXL (Workshop 1)
Location: Holiday Inn, Springfield, OR
Date: April 2nd, 2013  8:30 am - 4:00 pm

SkylineXL is a free public domain spreadsheet developed by the USDA Forest Service and Oregon State University. It uses an MS Office Excel Workbook to analyze ground or map profiles for skyline yarding systems to determine where to place skyline landings, skyline yarding boundaries, and the results of skyline payload capabilities. SkylineXL covers 4 different skyline configurations: standing skyline, multi-span skyline, running skyline and live skyline. The Workbook includes a database of widely used yarder and carriage combinations which can be applied to the user’s skyline profile to model configurations for skyline yarding objectives. SkylineXL has replaced the widely used LoggerPC and is compatible with XP Pro and Windows 7.

Attendees will need to bring a laptop with MS Office Excel 2007 or 2010 or be able to share a laptop since the workshop will include class exercises on the SkylineXL Workbook. Attendees should load SkylineXL 3.02 prior to the workshop or at the workshop. Attendees will receive laminated skyline yarding design sheets for field ring binders.


SkylineXL 3.02 can be downloaded for free at:


April 2nd,2013
8:30 Introduction to SkylineXL: Review of skyline yarding systems terminology, deflection, and yarder anatomy.
9:30 Break
9:45 Profile Input:  Attendees will input actual field profile traverse notes into SkylineXL to model a skyline profile.  A variety of Profile management attributes will be covered. A demonstration will be offered on pulling up a GIS map profile created from digital elevation and lidar models.
10:45 Break
11:00 SkylineXL Yarders and Carriages: Matching a carriage to a yarder. Adding new yarders or carriages.
Noon Lunch
1:00  Single Span Skyline Analysis: Attendees will fit a Single Span Standing Skyline to the sample profile by adjusting Skyline yarding parameters. This excercise will help users develop a skyline yarding design that maximizes yarding distance while achieving feasible payloads at the landing.
2:00 Break
2:15 Multispan Skyline Analysis: Attendees will fit a Multispan Skyline to the sample profile by adjusting Skyline yarding parameters. The SkylineXL warning features will be highlighted which alert users to deficiencies in selected yarding system designs.
3:15 Ground Truthing Your Analysis: Taking your SkylineXL analysis to the field to verify landing locations, tail tree locations, intermediate support locations, and skyline yarding boundaries.
 4:00 Adjourn
