HIGH-RESOLUTION TOPOGRAPHY OF MERCURY FROM MESSENGER ORBITAL STEREO IMAGING – THE SOUTHERN HEMISPHERE QUADRANGLES
Mercury MESSENGER Digital Terrain Models
2018/5/15
We produce high-resolution (222 m/grid element) Digital Terrain Models (DTMs) for Mercury using stereo images from the MESSENGER orbital mission. We have developed a scheme to process large numb...
Since the invention in 1980s, scanning probe microscopy (SPM) has been considered as the valuable avenue to visualize topography of sample in nanoscale. After more than 30-year development, SPMs have ...
CLOSE RANGE DIGITAL PHOTOGRAMMETRY APPLIED TO TOPOGRAPHY AND LANDSLIDE MEASUREMENTS
Close range photogrammetry Direct linear transformation Topography Landslide Image matching Huoyen Shan
2016/11/11
Landslide monitoring is a crucial tool for the prevention of hazards. It is often the only solution for the survey and the early-warning of large landslides cannot be stabilized. The objective of pres...
EXTRACTING ACCURATE AND PRECISE TOPOGRAPHY FROM LROC NARROW ANGLE CAMERA STEREO OBSERVATIONS
DEM/DTM Three-dimensional Application Planetary Mapping Geomorphology Modeling Processing
2016/11/8
The Lunar Reconnaissance Orbiter Camera (LROC) includes two identical Narrow Angle Cameras (NAC) that acquire meter scale imaging. Stereo observations are acquired by imaging from two or more orbits, ...
ACCURACY ASSESSMENT OF COASTAL TOPOGRAPHY DERIVED FROM UAV IMAGES
Digital Surface Model Coastal monitoring UAV photogrammetry Accuracy
2016/7/5
To monitor coastal environments, Unmanned Aerial Vehicle (UAV) is a low-cost and easy to use solution to enable data acquisition with high temporal frequency and spatial resolution. Compared to Light ...
TOPOGRAPHY OF GLACIERS AND ICE CAPS WITH SPOT 5 HRS
DTM Spot Image Space photogrammetry Spatial modelling Glaciology International Polar Year Stereoscopic Archiving
2015/12/29
Monitoring the evolution of glaciers, ice caps and ice streams in polar areas is of outmost importance because they constitute a good indicator of global climate change and contribute significantly to...
Documentation of Heritage Sites Using Surface Topography as Control
Close Range Photogrammetry Surfaces Modeling
2015/12/16
We present in this paper a model for the alignment of image sets using topographic data as control information. Traditional
photogrammetric practices are based on points as control entities. These po...
Calculating River Length Based on Topography Data
River Length Topographic Data Identifying Mainstream Centerline Multiple Criteria Decision
2015/12/11
River length has been the particular interest of people. Topographic data, which are obtained from field survey or digitizing from topographies, can serve as ideal data source for river length calcula...
INVESTIGATING FLUVIAL TOPOGRAPHY FORMING PROCESSES OF THE MARTIAN SURFACE BY MEANS OF RASTER BASED GEOMETRY ANALYSIS
DEM/DTM Raster based analysis Mars
2015/8/28
Recent Mars missions like ESA’s Mars Express (MEX) and NASA’s Mars Global Surveyor (MGS) capture the Martian surface at
high resolution and in 3D. For instance, the MEX instrument High Resolution Ste...
A two-layer sparse coding model learns simple and complex cell receptive fields and topography from natural images
Independent component analysis Natural images Neural networks Spatial vision
2015/8/10
The classical receptive fields of simple cells in the visual cortex have been shown to emerge from the statistical properties of natural images by forcing the cell responses to be maximally sparse, i....
Bottom Topography Observation in the Intertidal Zone Using the Camera Monitoring System
Orthoimage Monitoring Bathymetry Measurement Change Detection Oceanography
2015/7/30
The intertidal zone is characterized by periodic exposures to water level changes between high and low tides. Time series of
waterline changes during a flood/ebb cycle can be utilized for supplement...
Connections Between Ocean Bottom Topography and Earth's Climate
Ocean Bottom Topography Earth's Climate
2015/7/29
The seafloor is one of the critical controls on the ocean's general circulation. Its influence comes through a variety of mechanisms including the contribution of mixing in the ocean's interior throug...
The Role of Small-Scale Topography in Turbulent Mixing of the Global Ocean
Turbulent Mixing Global Ocean
2015/7/29
Maintenance of the observed basin-scale thermohaline (temperature T and salinity S) structure of the world's oceans appears to require mixing to provide dense abyssal waters, which are formed at high ...
Seafloor topography influences ocean circulation in two basic ways. First, it steers ocean flows. Second, it provides barriers that prevent deep waters from mixing, except within deep passageways that...
