Analyzing the performance of the different algorithms for extracting non-ground points on dense point clouds obtained from high spatial resolution images

Mina Mohammadi; Abbas Kiani

Volume 30, Issue 120 , March 2022, , Pages 7-26

https://doi.org/10.22131/sepehr.2022.251051

Abstract
  Extended Abstract Introduction DEMs (digital elevation models) are of critical importance in different areas such as land use planning, infrastructural project management, soil science, hydrology and flow direction studies. Across greater spatial scales, their usage is the key for contouring topographic ...  Read More

Accuracy assessment of Digital Elevation Models (DEM) of SRTM and ASTER satellites with precise ground observations (DGPS) Case study: from the Azad dam to the plain of Ghorveh-Dehgolan, Sanandaj

Mostafa Khabazi; Ali Mehrabi; Javad Arabi

Volume 28, Issue 111 , December 2019, , Pages 163-174

https://doi.org/10.22131/sepehr.2019.37515

Abstract
  Extended Abstract Introduction Digital elevation model (DEM) is the raster representation of the ground surface so that the information of each cell on the image has a value equal to the altitude from the sea level corresponding to the same spot on the ground. DEM is an appropriate tool for the generation ...  Read More

Avalanche hazard maps with satellite data and Digital Elevation Model

Abbas Khosravi

Volume 23, Issue 89 , May 2014, , Pages 26-31

Abstract
  Since the avalanche hazard map is a very time-consuming task, our goal is to improve the development of risk mapping models in vast remote areas. This model is based on satellite imagery and digital elevation model at two points of the Swiss Alps. To simulate avalanche hazards, the model (DEM) is programmed ...  Read More

Geomorphologic Characteristics of Mount. Erciyes Using DTM and RST Technologies

Bahram Azadbakht (Translator)

Volume 15, Issue 57 , May 2006, , Pages 16-18

Abstract
  Digital models of the Earth and satellite information through structural analysis of the Earth lead us to a new understanding of the relationship between volcano and the science of formation of the earth. A DTM was presented from the Mount Erciyes (3917m high), which is on the scale of 10 meters with ...  Read More
