Samsun-Atakum Orman Alanlarının Belirlenmesinde Farklı Bitki İndekslerinin Karşılaştırılması

Year 2019, Volume: 3 Issue: 1, 9 - 13, 04.03.2019

Abstract

Hayati açıdan önemli birçok jeokimyasal ve
biyoiklimsel sürece katkısı olması, yabani hayat için yaşam alanı ve besin
kaynağı oluşturması, insanlara doğrudan veya dolaylı olarak sosyoekonomik ürün
ve hizmet sağlaması gibi konularda kritik rol oynayan orman alanlarının
izlenmesi ve zamansal değişimlerinin analizi oldukça önemli bir konudur. Geniş
alan kaplayan orman alanlarının klasik yöntemlerle ölçülmesi ve izlenmesi çoğu
zaman hem maliyetli hem de zaman alıcıdır. Günümüzde, doğal kaynakların
izlenmesi, zamansal değişimlerinin belirlenmesi ve etkin yönetimi amacıyla çok
sayıda uzaktan algılama uydu sistemi geliştirilmiştir. Bu kapsamda, bitki
örtüsü de uydu görüntüleri ile periyodik olarak, etkin, ekonomik ve hızlı bir
şekilde takip edilebilir ve sonuçlar değerlendirilip gerekli tedbirler
alınabilir. Uydu görüntülerinden bitki örtüsünün elde edilmesi için birçok
bitki indeksi algoritması tanımlanmıştır. Bu çalışmada, 08 Eylül 2017 (Path:
175, Row: 31) tarihli Landsat 8 OLI uydu görüntüsü kullanılarak Samsun’un
Atakum ilçesine ait bitki örtüsü incelenmiştir. Bu amaçla NDVI, TVI, CTVI,
TTVI, RVI, NRVI olmak üzere 6 adet eğim tabanlı ve PVI1, PVI2, PVI3, DVI, SAVI,
TSAVI1, TSAVI2, MSAVI1, MSAVI2, WDVI olmak üzere 10 adet mesafe tabanlı bitki
indeksi kullanılmıştır. Toplam 16 bitki indeksinden elde edilen indeks görüntülerinde
eşik değerler uygulanarak orman alanları çıkartılmış ve sonuçlar Samsun Orman
İşletme Müdürlüğü’nden temin edilen yersel ölçmelere dayalı sınırlarla
karşılaştırılarak indekslerin orman alanlarının belirlenmesindeki performansı
karşılaştırılmıştır.

Comparison of Different Vegetation Indexes for Determination of Forest Areas in Atakum (Samsun, Turkey)

Year 2019, Volume: 3 Issue: 1, 9 - 13, 04.03.2019

Abstract

The monitoring and analyzing of temporal changes of forest areas, which
play a critical role in issues such as contributing to many vitally important
geochemical and bioclimatic processes, providing a habitat and food resource
for wildlife, providing direct or indirect socioeconomic products and services
to people, is a very important issue. Measuring and monitoring of large forest
areas using traditional methods are often costly and time-consuming. Today, a
large number of remote sensing satellite systems have been developed in order
to monitor natural resources, determine their temporal changes and manage them
effectively. In this context, vegetation cover can also be monitored
periodically, effectively, economically and fast with the satellite images and
the necessary measures can be taken by evaluating the results. Many vegetation
index algorithms have been developed for obtaining vegetation cover from
satellite images. In this study, the vegetation cover of Atakum district
(Samsun, Turkey) was investigated by using Landsat 8 OLI satellite image dated
September 08, 2017 (Path: 175, Row: 31). For this purpose, six slope-based
vegetation indexes including NDVI, TVI, CTVI, TTVI, RVI, and NRVI and ten
distance-based vegetation indexes including PVI1, PVI2, PVI3, DVI, SAVI,
TSAVI1, TSAVI2, MSAVI1, MSAVI2, and WDVI were used. Forest areas were extracted
from a total of sixteen index images by applying threshold values and the
performances of the vegetation indexes in the determination of forest areas
were compared by superimposing the index results with ground surveying-based
boundaries obtained from the Samsun Forestry Directorate.
