ASSESSMENT OF FLOODED AREAS PROJECTIONS AND FLOODS POTENTIAL IMPACTS APPLYING REMOTE SENSING IMAGERY AND DEMOGRAPHIC DATA
Floods Climate Change Impacts Climate Change Vulnerability
2016/11/30
Assessing vulnerability and potential impacts associated with extreme discharges requires an accurate topographic description in order to estimate the extension of flooded areas. However, in most popu...
Optimizing Content-Preserving Projections for Wide-Angle Images
Wide-Angle Images Optimizing Content-Preserving
2016/5/24
Any projection of a 3D scene into a wide-angle image unavoidably
results in distortion. Current projection methods either bend straight
lines in the scene, or locally distort the shapes of scene obj...
AUTOMATIC MULTI-VIEW TEXTURE MAPPING OF 3D SURFACE PROJECTIONS
Automation Heritage Conservation Laser Scanning Orthorectification Texture
2015/10/8
Texture-mapping in close-range photogrammetry focuses mostly on the generation of large-scale projections of 3D surfaces, the most
common instance being that of orthoimaging. Today, photogrammetry i...
3D BUILDING MODEL GENERATION FROM AIRBORNE LASER SCANNER DATA USING 2D GIS DATA AND ORTHOGONAL POINT CLOUD PROJECTIONS
LIDAR point cloud segmentation building model reconstruction automation
2015/8/13
Human operators use an intuitive procedure of rotating laser scanner point clouds into specific projections when trying to understand
the structure of buildings contained in the data. This procedure ...
Near Optimal Signal Recovery From Random Projections:Universal Encoding Strategies?
Random matrices singular values of random matrices signal recovery random projections concentration of measure sparsity trigonometric expansions uncertainty principle convex optimization duality in optimization linear programming
2015/6/17
Suppose we are given a vector f in a class F ⊂ RN, e.g. a class of digital signals or digital images. How many linear measurements do we need to make about f to be able to recover f to within pr...
Can we recover a signal f ∈ RN from a small number of linear measurements? A series of recent papers developed a collection of results showing that it is surprisingly possible to reconstruct certain t...
THE IMPACT OF CONFORMAL MAP PROJECTIONS ON DIRECT GEOREFERENCING
Aerial Triangulation Impact Analysis Mathematics
2015/3/24
If an aerial-triangulation (AT) is performed in the National Projection System (NPS), then the conformal map projection (which is
the base for the NPS) effects the results of the AT by raising three...
THE CARTOGRAPHIC PROJECTIONS FOR THE REPRESENTATION OF DOUBLE CURVED SURFACES
double curved surface control of topographic instruments geometric models digital images projections
2015/1/6
As is well known, the projection on the plane of a double curved surface is possible only by introducing warping techniques, be these either angular or superficial: the simple execution operation on t...
Climate Projections and Uncertainties over South America from MRI/JMA Global Model Experiments
Climate Projections High Resolution Global Model South America Uncertainties
2013/2/27
This paper analyses the climate change projected for the near and distant future in South America using MRI/JMA (Japanese Meteorological Agency) global model simulations with resolutions of 20 and 60 ...
Projections of hospitalised fall-related injury in NSW, Australia: Impacts on the hospital and aged care sectors
Falls Injury Older persons Projections Cost of injury
2012/3/22
Projections of the number, rate and cost of fall-related hospitalised injuries for individuals aged 65 years and older in New South Wales (NSW), Australia were estimated to 2051 for two scenarios: (1)...
The IAEA has released the latest update of its annual projections for the future of nuclear power, and both its low and high projections for 2030 are higher than they were last year. The low projectio...
3D Model Retrieval Based on Orthogonal Projections
3D model retrieval orthogonal projections moment invariants
2009/8/19
Recently with the development of 3D modeling and digitizing tools, more and more models have been created, which leads to the necessity of the technique of 3D mode retrieval system. In this paper we i...

2009/7/27
In this study, a new method is presented, based on genetic algorithms for determining object parameters such as radii and/or attenuation coefficients with some assumptions and estimating a cross-secti...
3D BUILDING MODEL GENERATION FROM AIRBORNE LASERSCANNER DATA BY STRAIGHT LINE DETECTION IN SPECIFIC ORTHOGONAL PROJECTIONS
LIDAR point cloud building model reconstruction
2015/6/1
The paper describes a novel approach for the generation of 3D building models from airborne laserscanner data, which is based on
the detection of straight lines in specific 2D projections of the dat...
