Diagnostic tools for 3D unstructured oceanographic data
Most ocean models in current use are built upon structured meshes. It follows that most existing tools for extracting diagnostic quantities (volume and surface integrals, for example) from ocean model output are constructed using techniques and software tools which assume structured meshes. The greater complexity inherent in unstructured meshes (especially fully unstructured grids which are uns...
متن کاملPhD Showcase: 3D Oceanographic Data Compression Using 3D-ODETLAP
This paper describes a 3D environmental data compression technique for oceanographic datasets. With proper point selection, our method approximates uncompressed marine data using an over-determined system of linear equations based on (but essentially different from) the Laplacian partial differential equation. Then this approximation is refined via an error metric. These two steps work alternat...
متن کاملNonparametric Regression Estimation under Kernel Polynomial Model for Unstructured Data
The nonparametric estimation(NE) of kernel polynomial regression (KPR) model is a powerful tool to visually depict the effect of covariates on response variable, when there exist unstructured and heterogeneous data. In this paper we introduce KPR model that is the mixture of nonparametric regression models with bootstrap algorithm, which is considered in a heterogeneous and unstructured framewo...
متن کاملInteracting with 4D oceanographic volume data using GeoAnalytics tools
The need to turn environmental statistical data into knowledge and make decisions based on large amounts of multivariate, time-varying and geospatial information represent a major challenge for the analyst. These information streams, often in time-critical situations, demands efficient, integrated and interactive tools that aid the user to explore, present and communicate large information spac...
متن کاملVCLab's Tools for 3D range data processing
Post-processing of 3D scanned data is still the bottleneck for a wider diffusion of this technology. In this paper we describe our second generation tools for processing 3D scanned data. In particular, our tools support: range maps alignment, range maps merge (or fusion), mesh simplification and color attribute management. This software package has been implemented by scratch and encompasses bo...
