Biodiversity and Ecosystem Informatics - BDEI - Spatial Data Infrastructure for Ecological Research (Planning Grant)

生物多样性和生态系统信息学研究议程（http://bio.gsfc.nasa.gov）指出，目前无法跨空间尺度比较数据是一个关键问题：“来自不同来源的生物数据经常被收集并以不同的尺度和分辨率呈现，当需要多个数据集进行数据合成和分析时，会导致细节的丢失。”这项资助汇集了一个由生态学家和计算机科学家组成的团队，为“生态科学的空间数据基础设施”计划一项提案。提出的基础设施将允许科学家通过将适当的“空间”构建块放在一起来定义数据集——构建块以概念上熟悉的、特定于领域的术语表示。这样构建（或重铸）的数据集将适用于空间位置和测量与自动空间数据转换的自动集成。这将允许对个别实地数据集进行空间分析，并将空间基础设施内定义的相同和不同空间尺度的数据集联系在一起。我们的目标是包括提高生产力的研究工具，如现场数据收集设备和数据验证和分析，并在研究周期的早期用元数据自动标记现场数据。我们也为元数据和数据的合成做出了贡献。

EIA-0131952Cushing, JudithEvergreen State CollegeBDEI: Spatial Data Infrastructure for Ecological Research (Planning Grant)SummaryThe Biodiversity and Ecosystem Informatics Research Agenda (http://bio.gsfc.nasa.gov) notesthe current inability to compare data across spatial scales as a critical problem: "Biological datafrom different sources are frequently collected and presented in different scales and resolutionsresulting in a loss of detail when multiple data sets are required for data synthesis and analysis".This grant brings together a team of ecologists and computer scientists to plan a proposal for a"Spatial Data Infrastructure for Ecological Sciences." The proposed infrastructure would allow ascientist to define a data set by putting together the proper "spatial." building blocks -- buildingblocks represented in conceptually familiar, domain-specific terms. Data sets thus constructed(or recast) would be amenable to the automatic integration of spatial locations and measurementswith automatic spatial data transformations.This would allow spatial analysis of individual field data sets and the linking together at sameand different spatial scales data sets defined within the spatial infrastructure. We aim to includeproductivity enhancing research tools such as field data gathering devices and data validationand analysis, and to automatically tag field data with metadata early in the research cycle. Wethus also contribute to the synthesis of metadata and data.
