Assessment of digital terrain model (DTM) generate from UAV aerial image using photogrammetric image processing module / Intan Shahirah Sobri

The Digital Terrain Model (DTM) were presented about bare surface of the earth. It is produce DTM from data Unmanned Aerial Vehicle (UAV). However, the lack of processing will caused error and the result produce erroneous DTM result (Zietara 2017). Therefore, this study to assess the accuracy of th...
