GENERATION OF THE 30 M-MESH GLOBAL DIGITAL SURFACE MODEL BY ALOS PRISM [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2016 Topographical information is fundamental to many geo-spatial related information and applications on Earth. Remote sensing satellites have the advantage in such fields because they are capable of global observation and repeatedly. Several satellite-based

Evaluation of Recently Released Open Global Digital Elevation Models of Hubei, China
Remote Sensing, 2017 The recent release of worldwide SRTM 1 DEM and AW3D30 adds new members to the open global medium resolution (90–30 m ground spacing) digital elevation models. Together with the previously existing SRTM 3 and ASTER GDEM, their quality is of great interest

RESEARCH ON HIGH PRECISON DEM OF URBAN AREA BASED ON TERRASAR-X/TANDEM-X [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020 Digital elevation model (DEM) is an important geospatial data, which can provide a lot of topographic information. Currently, most commonly DEM data is derived from SAR images acquired before 2011, which has poor timeliness and is difficult to reflect ...

Problems of spatially distributed quantitative evaluation of soil erosion losses
Вісник Харківського національного університету імені В.Н. Каразіна. Серія Геологія. Географія. Екологія, 2022 Formulation of the problem. Water erosion of soils is the most widespread and dangerous soil degradation process in Ukraine. The development of an effective system of soil protection measures requires the use of spatially distributed mathematical models ...
