INFORMATION CONTENT ANALYSIS FROM VERY HIGH RESOLUTION OPTICAL SPACE IMAGERY FOR UPDATING SPATIAL DATABASE
Information Content Topographing Mapping GIS Remote Sensing VHR Images
2018/11/9
High resolution satellite images started with IKONOS imagery. After the launch of the very high resolution IKONOS in the 1990s, a new generation of commercial Earth-imaging satellites have pioneered a...
SEMI AUTOMATED LAND COVER LAYER UPDATING PROCESS UTILIZING SPECTRAL ANALYSIS AND GIS DATA FUSION
NTDB (National Topographic Data Base), Segmentation, Classification, nDSM, data fusion
2018/5/11
Technological improvements made in recent years of mass data gathering and analyzing, influenced the traditional methods of updating and forming of the national topographic database. It has brought a ...
DOM AND DEM SYNCHRONIZATION EDITIONG AND UPDATING METHOD BASED ON GEOMORPHOLOGICAL CHANGE DETECTION
DOM DEM Geomorphological Change Detection Synchronization Editing Updating Method
2018/5/11
Aiming at the deficiency of the existing DOM and DEM production modes and the networking and automation requirements of the information mapping production system, a method of network-based simultaneou...
ON-LINE INTEGRATION OF GIS AND GPS FOR AUTOMATIC AND INTELLIGENT UPDATING OF SPATIAL DATA
Automatic GPS GIS Integrated Systems Rule-based system spatial data Updating
2015/9/28
One of the most expensive stages in implementation of a GIS system is preparation of spatial data to be entered to the system. It can be said that about 60-80 percent of the project cost is spent for ...

A TECHNIQUE FOR UPDATING HIERARCHICAL SKELETONIZATION-BASED FACTORIZATIONS OF INTEGRAL OPERATORS
factorization updating local perturbations hierarchical factorizations integral equations
2015/7/14
We present a method for updating certain hierarchical factorizations for solving linear integral equations with elliptic kernels. In particular, given a factorization corresponding to some initial geo...
GPGPU for orbital function evaluation with a new updating scheme
GPGPU orbital function evaluation new updating scheme Computational Physics
2012/4/19
We accelerated an {\it ab-initio} QMC electronic structure calculation by using GPGPU. The bottleneck of the calculation for extended solid systems is replaced by CUDA-GPGPU subroutine kernels which b...
A new version of the European tsunami catalogue: updating and revision
A new version the European tsunami catalogue updating and revision
2009/12/9
A new version of the European catalogue of tsunamis is presented here. It differs from the latest release of the catalogue that was produced in 1998 and is known as GITEC tsunami catalogue in some imp...

Assessing the performance of eight real-time updating models and procedures for the Brosna River
Brosna River Galway River Flow Modelling and Forecasting System Neural Network Updating Linear Transfer Function
2009/5/18
The flow forecasting performance of eight updating models, incorporated in the Galway River Flow Modelling and Forecasting System (GFMFS), was assessed using daily data (rainfall, evaporation and disc...
Technical Note：Updating procedure for flood forecasting with conceptual HBV-type models
flood forecasting conceptual HBV-type models rainfall-runoff model
2009/5/15
Flood forecasting is of increasing importance as it comes to an increasing variability in global and local climates. But rainfall-runoff models are far from being perfect. In order to achieve a better...
Calibration and sequential updating of a coupled hydrologic-hydraulic model using remote sensing-derived water stages
flood forecasting system rainfall-runoff
2009/4/28
Two of the most relevant components of any flood forecasting system, namely the rainfall-runoff and flood inundation models, increasingly benefit from the availability of spatially distributed Earth O...
A non-linear neural network technique for updating of river flow forecasts
Auto-Regressive Exogenous-input model neural network
2009/3/24
A non-linear Auto-Regressive Exogenous-input model (NARXM) river flow forecasting output-updating procedure is presented. This updating procedure is based on the structure of a multi-layer neural netw...
Comparison of three updating schemes using artificial neural network in flow forecasting
artificial neural network (ANN) updating flow forecasting backpropagation method
2009/3/5
Three updating schemes using artificial neural network (ANN) in flow forecasting are compared in terms of model efficiency. The first is the ANN model in the simulation mode plus an autoregressive (AR...
