Quality assessment of DTM generated from RTK GPS data on area with various sky views
Most of civil engineering projects are in large scale applications which need high-resolution DTM. The use of DTM in civil engineering projects has always been assessed from technical and financial point of view, particularly on the data collection stage where greatest time and cost are recognized....
