Abstract

Information systems and information technologies are very essential terms in today’s information society. Spatial information systems are important branch of information systems. Geographical Information Systems (GIS) are included in spatial information systems category. Most of the problems encountered in the organizations have a spatial aspect. Thus analyzing spatial data has a wide importance for most of the organizations. Decision making is a complex process influenced by several factors. GIS helps decision makers to make the decision and plays an important role in decision making at various levels in organizations. The purpose of this study is to show how GIS can facilitate decision making process and can be used as a decision tool in forest management. The viewshed analyses, constitution of three dimensional, slope and aspect maps of the study area and development of a user interface in MapInfo GIS using MapBasic software are among the analyses done in this study.

Keywords

ORMAN YÖNETİMİNDE KARAR DESTEK SİSTEMİ OLARAK COĞRAFİ BİLGİ SİSTEMLERİ

Abstract

Bilgi sistemleri ve bilgi teknolojileri günümüzün bilgi toplumunda oldukça önemli kavramlardır. Coğrafi Bilgi Sistemleri (CBS), konumsal bilgi sistemleri kategorisinde yer almaktadır. Organizasyonlarda karşılaşılan problemlerin çoğunun konumsal bir yönü bulunmaktadır. Bu nedenle çoğu organizasyon için konumsal verilerin analizi büyük bir önem taşımaktadır. Karar verme çeşitli faktörlerden etkilenen karmaşık bir süreçtir. CBS organizasyonlarda çeşitli düzeylerde karar vermede yardımcı olmaktadır. Bu çalışmanın amacı, CBS’nin karar verme sürecini nasıl kolaylaştırabileceğini ve orman yönetiminde bir karar destek sistemi olarak nasıl kullanılabileceğini göstermektir. Görülebilen alan analizi, çalışma alanının üç boyutlu haritasının, eğim ve bakı haritalarının oluşturulması ve MapBasic paket programını kullanarak MapInfo GIS içinde kullanıcı arayüzünün geliştirilmesi bu çalışmada yapılan analizler arasındadır.
