General System description
System name: Conifer Timber Quality
Brief overview
Part of the GB Forestry Decision Support System, this tool enables the user to get some Sitka spruce timber features as the percentage of juvenile wood, the average denisty, etc.
Contents
Scope of the system
This system insists on the influence of stand characteristics as stocking density, yield class or thinning treatments in the quality of the wood obtained from this stands.
System origin
- Currently free to use via web.
- It was developed to be used among researchers.
Support for specific issues
Timber quality analysis.
Support for specific thematic areas of a problem type
- Silvicultural
- Development choices / land use zoning
- Policy/intervention alternatives
- Sustainability impact assessment (SIA)
Capability to support decision making phases
Allows user to vary management options in order to obtain better quality wood
Related systems
Describe (and/or link to) other systems related
Data and data models
Typical spatial extent of application
Web based tool operates at stand scale, as the wood quality characteristics resulting belongs always to trees growing in stockings.
Type of information input from user (via GUI)
Species (at this moment only stika spruce is allowed), yield class, age, stocking density and thinnings schedule.
Models
Forest models
Growing models and wood quality models. Models are only available for Sitka spruce at this moment, due to be expanded to cover Scots Pine in 2009/2010 as well as further timber properties.
Decision Support
Definition of management interventions
Silvicultural interventions in obtained wood quality.
Typical temporal scale of application
Has some support for future climate scenarios, baseline data is from 1961-1990.
Types of decisions supported
- Management level
- strategic decisions
- administrative decisions
- operating control decisions
- Management function
- planning decisions
- organizing decisions
- command decisions
- control decisions
- coordination decisions
Output
Types of outputs
Current version generates tables via web.
System
System requirements
- Java library deployed on Linux and Windows. UI available via web.
Architecture and major DSS components
Web Java, C#, 3D visualisation system with Java and VTK
Usage
Computational limitations
User interface
Web UI requires some understanding of yield classes and wood quality requirements and measures.
Documentation and support
Installation
- Prerequisite knowledge: Only requires a web browser and an internet access.
