Automatic selection of permanent scatterers-based GCPs for refinement and reflattening in InSAR DEM generation

open access: yesInternational Journal of Digital Earth, 2022
In DEM generation using interferometric synthetic aperture radar (InSAR), the ground control points (GCPs) for refinement and reflattening are usually selected by manual selection, field surveying, GPS points and existing basemaps, which may not be ...

Uncertainty Analysis for Image-Based Streamflow Measurement: The Influence of Ground Control Points

open access: yes, 2022
Large-scale particle image velocimetry (LSPIV) provides a cost-effective, rapid, and secure monitoring tool for streamflow measurements. However, surveys of ground control points (GCPs) might affect the camera parameters through the solution of ...

ANALISIS PENGARUH SEBARAN GCP (GROUND CONTROL POINT) TERHADAP AKURASI HASIL ORTHOPHOTO DI PIT CENDANA PT KALIMANTAN PRIMA PERSADA SITE BRE [PDF]

open access: yesJurnal GEOSAPTA, 2019
Kelemahan dari foto udara adalah masih belum didapatkannya cara yang bisa membuat tingkat akurasi dari hasil proses foto udara itu sendiri menjadi memilki tingkat akurasi yang tinggi dan masih belum bisa diperkirakan seberapa baik tingkat akurasi yang akan didapatkan dari proses foto udara itu sendiri. Namun keuntungan dari foto udara ini sendiri yaitu
