ABOUT THE CASE STUDY It is better to tell about some forestry terminology that was used in this case study. “Forestry plans” are used for management of wide areas that forests cover. These plans are changed in every ten years. According to these plans, forest area is divided into smaller partitions, called “stand”. A “stand” is a group of trees with2. similar stage of development and structures that enables to produce a local climate in current place. This is the smallest administration part in forestry plans and the minimum area for a stand is accepted as “1.0 hectare”. There are working teams which are responsible for stand areas’ care and the application of forestry plan to each stand. “Administration period” defines the economic cutting time at stand areas. This period is related to tree type, growing area...It usually takes 50-200 years long. So after this long period, the mistakes or missing of the plan is appeared that’s why the forestry plans are essential and need so much care while creating. “Canopy closure class”; In a stand area the closure of hillsides at trees which shows the shelter degree on the ground. These degrees are: 178 * Degreee "0" — canopy closure class is smaller than %10, means widely apart, e. Degreee "1" — canopy closure class is between 9611-40, means less closed, e Degreee "2" — canopy closure class is between 9941-70, means middle closed, e Degreee "3" — canopy closure class is bigger than 9670, means closed. "Stage of development" is the classification by diameter of tree stems. These classifications are: e Class "a" means the diameter of tree stem is equal or smaller than 7.9cm. e Class "b" means the diameter of tree stem is between (8.0-19.90)em. e (lass “c” means the diameter of tree stem is between (20.0-35.90)cm. e Class "d" means the diameter of tree stem is equal or bigger than 39.0cm. In a stand area there can be more than one type of tree. It is limited with three types of trees in this case study. All types were entered into database. So the stage of development and canopy closure class are different for different types of tree that were also entered for each type of tree. "Cutting" means, the area of trees (m? : ha) in administration that is going to be cut. "Care" shows which type of care system is used in stand. "Planting space", if any new trees are planning to plant, planting spaces shows in how many meters will be between the new planted trees. "Cover type", the danger type such as insects that the stand area will be effected. “New growth”, is about the study in ecologic factors on new growth plants. The three steps are used in forest information system, too. 1. Sytem Analysis : It is necessary to discuss with geospatial data users before this step. Trying to define the problems, needs, requirements. During this case study, there was no geographic information system in administration. It was better to discuss about GIS and advantages of it, in the beginning of study with the administration staff. Then the requirements and problems were discussed and defined with administration staff. A paper map (1:5000) and relevant documents were obtained. The paper map was about forestry plan. Feasibility study helps whether the concepts about the system is realistic. 2. Sytem Design As it was defined before the administration is divided into smaller partitions, called “stand”. Except the technical benefits on smaller partitions of administration, one more benefit is easy management. There were geometries and attributes in forestry plan. There are usullay has three simple geometry, “point, line, polygon”.In this case study, it was decided to use two layers: “Stand”, the table name is “mes _alan”, “Road”, the table name is *yol kod", Stand layers’ geometry is “polygon”, Road layers’ geometry is “line”. Attributes in mes alan" table; bolme no : stand number msc tp kod :types of trees msc kapa : canopy closure class glsm cag : stage of development mkat1 : the first type of tree in the stand
