Özet:

 Since early civilizations, the growing need for information has driven continuous advancements in surveying and photogrammetry, particularly with modern technologies enhancing measurement techniques and the integration of global positioning systems across terrestrial, aerial, and satellite platforms. Since the early twenty-first century, technologies such as GPS, mobile phones, GNSS-CORS, and UAVs have rapidly become integral to practical measurements across various sectors, including construction, mining, aviation, agriculture, and forestry. In this study, topographic measurement devices with different measurement sensitivities, such as GPS, GNSS-CORS, mobile phones and UAVs, were measured in the same size area and compared in terms of measurement time, precision and mapping. In addition, digital elevation values were calculated for the same area and mapped in the Google Earth software environment from satellite data, a widely referenced remote sensing dataset. These different measurement data obtained were compared on the same plane and as a result, it was determined that GNSS-CORS and RTK-UAV devices with RTK provided high precision data, followed by UAV without RTK device, Google Earth data set, mobile phone and GPS device. Upon examination of the results of this study, it was determined that UAV technology is particularly compatible with research endeavors demanding high precision and rapid data acquisition. Conversely, for studies where high sensitivity is not a primary consideration, measurements derived from GPS and mobile phone data may offer a suitable alternative.

 Eski medeniyetlerden bu yana, artan bilgi ihtiyacı, özellikle ölçüm tekniklerini ve küresel konumlandırma sistemlerinin karasal, hava ve uydu platformları arasında entegrasyonunu geliştiren modern teknolojilerle birlikte, arazi ölçümü ve fotogrametri alanında sürekli ilerlemelere yol açmıştır. Yirmi birinci yüzyılın başlarından bu yana, GPS, cep telefonları, GNSS-CORS ve İHAlar gibi teknolojiler, inşaat, madencilik, havacılık, tarım ve ormancılık dahil olmak üzere çeşitli sektörlerde pratik ölçümlerin ayrılmaz bir parçası haline gelmiştir. Bu çalışmada, GPS, GNSS-CORS, cep telefonları ve İHAlar gibi farklı ölçüm hassasiyetlerine sahip topoğrafik ölçüm cihazları aynı büyüklükteki alanda ölçülmüş ve ölçüm süresi, hassasiyet ve haritalama açısından karşılaştırılmıştır. Ayrıca, aynı alan için sayısal yükseklik değerleri hesaplanmış ve yaygın olarak referans alınan bir uzaktan algılama veri kümesi olan uydu verilerinden Google Earth yazılım ortamında haritalanmıştır. Elde edilen bu farklı ölçüm verileri aynı düzlemde karşılaştırılmış ve sonuç olarak RTK özellikli GNSS-CORS ve RTK-İHA cihazlarının yüksek hassasiyetli veri sağladığı, bunu RTK cihazı olmayan İHA, Google Earth veri seti, cep telefonu ve GPS cihazının izlediği belirlenmiştir. Çalışmada elde edilen sonuçlar incelendiğinde, yüksek hassasiyet ve kısa süreli ölçüm gerektiren çalışmalarda İHA kullanımının daha etkili olduğu, yüksek hassasiyet istenmeyen çalışmalarda ise GPS ve cep telefonu ile yapılan ölçümlerin kullanılabileceği sonucuna varılmıştır.
