Abstract
Digital fotogrametrik nirengi yöntemiyle üretilen ortofoto haritaların doğruluk değerlendirmesi, üretim sürecini etkileyen çok sayıda parametre olması nedeniyle karmaşık bir konudur. Bu çalışmada Kocaeli ilinde kinematik GPS/IMU destekli fotogrametrik nirengi yöntemiyle üretilen 1:5000 ölçekli sayısal fotogrametrik harita ve ortofotoların geometrik doğruluğunun değerlendirilmesi amaçlanmıştır. Proje sahasında blok içinde yer alan yer kontrol ağının geometrik doğruluk kalitesi, üretilen haritaların doğruluğuna yansıyacağından göz önünde bulundurulması gereken bir husustur. Kocaeli kenti Kuzey Anadolu Fay Sistemi üzerinde bulunduğundan, bölgede zeminin jeoteknik özellikleri nedeniyle mevcut yer kontrol ağı noktalarında ve özellikle İzmit Körfezi kıyı boyunca zeminde kararsızlık problemi oluştuğu da bilinmektedir. Bu nedenle belirtilen problemin, projede fotogrametrik nirengi blok doğruluğuna ve 15 cm yer örnekleme aralığı ile üretilen ortofoto haritaların doğruluk değerlerine hangi düzeyde yansıdığını araştırmak önem kazanmıştır. Bu amaçla zemin kararsızlığı tespit edilmiş olan körfez kıyı alanlarında GPS ile arazi kontrol ölçmeleri yapılarak doğruluk değerlendirmesi yapılması planlanmış ve belirtilen sahalarda digital ortofoto üzerinde seçilen detaylar, arazide kontrol amaçlı olarak GPS ile ölçülmüş ve elde edilen nokta konum koordinatları karşılaştırılmıştır. Arazi ve ortofoto üzerinden üretilen noktaların planimetrik doğruluklarının ortalaması 31.5 cm olarak elde edilmiş olup; harita ölçeği dikkate alındığında elde edilen sonuç bulguların BÖHYY’de öngörülen hata sınırları içerisinde ve uluslararası standartlara da uygun olduğu görülmüştür.
