The LSA Analyst is an extension for ArcView GIS 3.x.

Features:

• creates reaches from streams, where reaches are defined by linear zones of similar slope and azimuth
• creates multiple nested buffers for defining core, inner, and outer riparian management zones (RMZs)
• creates "buffer management units" (BMUs): regions defined by position within respective RMZ and proximity to reach units
• runs the Jason Cross LSA algorithm for defining stream shading and large woody debris recruitment based on topographic position and forest stand inventory
• displays reaches according to shading at different times of the day

Requirements:

• ArcView GIS 3.2 or higher (but NOT ArcView 8 or higher)
• ArcView GIS Spatial Analyst Extension
• vector stream data
• digital elevation model
• forest stand polygons with a separate detailed inventory data file

Outputs:

• vector reach data with stream shading and large woody debris attributes
• "buffer management unit" polygon vector data
