+}}
-SGIS is a tool for 1. Simulation of forest development and 2. Optimization of forest treatments in a GIS-user interface!
+{{DSS, Concrete application
+|Has typical use case=Research, consultancy commissions, practical forest planning
-=== System origin ===
+|Has country=Norway
-The current version of SGIS is based on a prototype developed in PC-ArcInfo (Næsset 1997).
+|Has number of users=N/A
+|Has number of real-life applications=N/A
-SGIS is based on ArcView version 8 (9) and is programmed in Visual Basic for Applications.
+|Has utilisation in education=N/A
+}}
-SGIS consist of a functionality specially made for forest related problems and standard ArcView GIS-functionality.

-== Data and data models ==
+{{DSS, DSS development
+|Has DSS development=SGIS.Description of DSS development
-=== Typical spatial extent of application  ===
+}}
-The primary unit of SGIS is usually the forest stand or sometimes even a smaller unit if sufficient data for such units can be provided.
+{{DSS, Documentation
+|Has technical documentation=No
-=== Forest data input  ===
+}}
-Digitized stands boundaries and the stand database can be imported from forest management planning systems.
-=== Type of information input from user (via GUI) ===
-Stand treatments schedules and spatial constraints (buffers, adjacencies, etc.). Number of 5- or 10-year periods used for calculations. Also, allowable treatments in each stand is prescribed. The planner must specify an objective function and constraints too. Otherwise, default objective function would be the maximization of NPV subject to a non-declining felling path.
-== Models ==
-=== Forest models ===
-Once stand treatments schedules and spatial constraints are defined, [[GAYA-JLP|GAYA]] stand simulator is used. GAYA provides the future development of stand variables such as diameter, height, volume and value increment over time.
-== Decision Support ==
-=== Definition of management interventions ===
-Time of harvest, plantations, thinnings, reconversions...
-=== Typical temporal scale of application ===
-Although being data collected at stand level, the application was developed in order to join multiple stands and reach conclusions at a strategy planning level.
-=== 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
-*decision making situation
-**unilateral
-**collegial
-**Bargaining / participative decision making
-=== Decision-making processes and models ===
-*Logic modeling
-*Operations research modeling
-**Direct approaches
-*Simulation (with and without stochasticity)
-*Multiple criteria/ranking
-== Output ==
-=== Types of  outputs ===
-Results are displayed in tabular reports summarizing quantities, values, etc. of the optimal solution, shadow prices, and the amount of area devoted to the various treatments in each period.
-They are also showed simple three-dimensional visualization of clear-felled areas in digital elevation models (DEM) as well as thematic maps presented on the computer screen or on paper showing, for example, the age class distribution of a selected period.
-=== Spatial analysis capabilities  ===
-SGIS uses facilities of ARC/INFO in order to allow the input or edition of data and spatial constraints. Then, spatial results are showed, enabling a further spatial analysis through the comparison of previous runs where other planning strategies were used.
-=== Abilities to address interdisciplinary, multi-scaled, and political issues  ===
-SGIS analysis tool can solve not only forest treatment scheduling problems, but also others like finding mountain sides of greater slopes than 40% suitable as goshawk habitats, corridors of old growth forest relating specific patches, etc.
-== System ==
-=== System requirements  ===
-* Operating Systems: MS Windoes OS
-* Other software needed: ARC/INFO
-* Development status:
-=== Architecture and major DSS components ===
-The SGIS was developed by synthesizing commercially available software and well-documented software from previous forest research projects in Scandinavia. It was composed by a common menu-driven graphical user interface for the forest model and a GIS within the GIS environment. It was developed by the simple macro language (SML) facilities of pcARC/INFO.
-GAYA stand simulator and [[JLP]] linear programming (LP) program are also used.
-=== Usage ===
-Describe the level of use: Research level use, Industry use, Government use
-=== Computational limitations ===
-When it was developed, those days hardware and software limitations excluded very large decision problems, owing to long response time. In the largest areas, spatial constraints such as adjacency can be unable to be solved by linear programming.
-=== User interface ===
-Describe the quality of user interface and the Prerequisite knowledge for using the system
-=== Documentation and support ===
-Describe the connection to Help-system and possibilities for assistance, as well as the required training and user support levels
-=== Installation ===
-* Prerequisite knowledge: Level of effort to become functional
-* Cost: (purchase price, development costs, demonstrated return on investment, cost of use, training costs, licence and maintenance costs)
-* Demo: allows the download/utilization of a trial version. If yes, where is it available and what are the trial conditions.
