项目摘要

Advances in digital imaging methods are revolutionizing a wide range of scientific disciplines by facilitating the acquisition of huge amounts of data that allow the visualization and analysis of complex, multidimensional images. Concurrently, modern computing technologies enable numerical modeling of a broad gamut of scientific phenomena, resulting in vast quantities of numerical data, which are just the starting point for the scientific exploration that modern computational and visualization methods enable. This is particularly true in the biological and geosciences, two seemingly very different disciplines. These capabilities come with a cost: increasing data size and complexity require more sophisticated methods for data analysis and visualization. This project will conduct research that will lead to a common software framework for supporting a multi scale progressive data refinement method based upon the representation of the data as a wavelet expansion, and enabling interactive exploration of large data sets for the bio and geoscience communities. The development of a general toolkit for wavelet based representations of data will have broad impact, allowing the multi scale analysis, storage, and visualization for data collected in a wide range of fields and on a multitude of platforms, from high end computing facilities to laptop computers used by students, field biologists, and others.Analysis and visualization of large data sets play an important role in scientific discovery. Efficient, and broadly available tools to accomplish these tasks are crucial for a wide range of scientific and educational fields. However, efficient analysis and visualization is a non trivial problem as the size and complexity of data increases. This research addresses this challenge through a general progressive access, multi scale data representation for efficient handling of structured data sets across a range of science domains. The development is based upon a wavelet enabled data representation developed by NCAR for geoscience applications. The tools will utilize the very flexible and open source standard NetCDF format, and the methods will be documented as a set of conventions and a toolkit developed that incorporates and integrates these components for dissemination. In addition to an open source toolkit, these tools will be integrated into the VAPOR (NCAR) and STK (CSCI) platforms, thus expanding the capabilities and efficiencies of these platforms for the geo and bio sciences communities, respectively. Advancements generated by this project will be openly disseminated to the user community through an open source toolkit.

数字成像方法的进步正在通过促进大量数据的获取来彻底改变广泛的科学学科，这些数据允许对复杂的多维图像进行可视化和分析。与此同时，现代计算技术使广泛的科学现象的数值建模，产生大量的数值数据，这只是现代计算和可视化方法使科学探索的起点。这在生物学和地球科学这两个看似非常不同的学科中尤其如此。这些功能是有代价的：不断增加的数据大小和复杂性需要更复杂的数据分析和可视化方法。该项目将进行研究，以建立一个通用软件框架，支持基于小波扩展数据表示的多尺度渐进数据细化方法，并使生物和地球科学界能够对大型数据集进行交互式探索。基于小波的数据表示的通用工具包的开发将产生广泛的影响，允许多尺度分析，存储和可视化的数据收集在广泛的领域和众多的平台上，从高端计算设备到笔记本电脑使用的学生，现场生物学家，和otherwise。高效且广泛可用的工具来完成这些任务对于广泛的科学和教育领域至关重要。然而，随着数据的大小和复杂性的增加，高效的分析和可视化是一个重要的问题。本研究通过一种通用的渐进式访问，多尺度数据表示来解决这一挑战，以有效处理一系列科学领域的结构化数据集。该工具将利用非常灵活和开放源码的标准NetCDF格式，所用方法将作为一套惯例和一个工具包加以记录，该工具包将纳入和整合这些组成部分，以便传播。除了开源工具包外，这些工具将被整合到VAPOR（NCAR）和STK（CSCI）平台中，从而分别为地球科学和生物科学界扩展这些平台的能力和效率。该项目产生的进步将通过一个开放源码工具包向用户社区公开传播。
