Hava Lazer Tarama Sistemi, Uygulama Alanları ve Kullanılan Yazılımlara Genel Bir Bakış

Öz

Hava LiDAR sistemleri bir hava aracının altına monte edilen tarayıcıdan gönderilen lazer ışının gidiş-dönüş süresini kaydederek yer objeleri ve algılayıcı arasındaki mesafeyi hesaplayan aktif bir ölçme sistemidir. Sistem dâhilinde bulunan GPS ve INS sistemlerinden alınan konum ve dönüklük verisi ile beraber taranan objeye ait konum hesaplanır. Bu şekilde yeryüzüne binlerce lazer ışını gönderebilen sistem, fiziksel yeryüzüne ait yüksek yoğunluklu ve referanslandırılmış üç boyutlu (3B) veri doğrudan elde edilmektedir. Klasik ölçmeler ile yaklaşık aynı doğrulukta, hava fotogrametrisinden daha hızlı oluşturmaya imkân vermektedir. Bu çalışmada hava LiDAR sistemlerine genel bir bakış ile beraber günümüzdeki uygulama alanları, kullanılan lisanslı ve lisanssız yazılımlar ve veri sağlayıcılar ile ilgili bilgi verilmektedir.
