WORKSHOP TO IDENTIFY GROUND-BASED DIGITAL AQUISITION, ANALYSIS, AND VISUALIZATION NEEDS OF THE GEOLOGICAL SCIENCE COMMUNITY

这项拨款将支持一个地球科学社区研讨会，以确定地质科学社区的地面数字采集、分析和可视化需求。在爱达荷大学John Oldow的指导下，将于2006年初冬组织两次研讨会。许多地球科学家目前面临的挑战是获取和培训数字野外测绘工具的使用，以及合并以不同分辨率获得的数字数据集和使用多种工具的复杂性。开发用户友好的开源软件来处理和分析数字地图产品是一个明确的需求，也是一个相当大的挑战。研讨会将重点讨论可能开发的新设施/服务，以支持使用地面激光扫描（TLS）、GPS、数字摄影测量和遥感图像（例如卫星或机载多光谱图像）以及更传统的现场测绘工具等技术的最先进的数字地质现场测绘。该设施概念被称为INTERFACE（跨学科数字现场数据采集和探索联盟），将为美国各地的研究人员和学生提供设备、培训、数据处理、数据存档和可视化设施，以支持直接的数字数据采集和地表地形的可视化。讲习班的具体目标是：(1)确定数字数据采集所需的方法和技术，(2)探索数据库和分析工具需求，(3)概述设备可访问性、培训、分析和数据存档的国家系统架构愿景，(4)发起关于数据标准、所需元数据和数据库信息格式的讨论，(5)确定与数字采集方法相关的可视化需求，(6)制定社区参与和实施数字采集系统的战略；(7)概述数字采集系统与地球科学中现有或计划中的网络基础设施举措的关系。计划约有25名代表广泛专业知识的地球科学家出席会议。参加者将来自地貌学、构造学、地震和大地测量学领域，并有针对性地邀请具有数字采集、数据库开发、信息管理和数据分析工具应用经验的人参加。研讨会的研究结果将在2006年美国地质学会全国会议和美国地球物理联合会秋季会议上提交给地质界，此外还有一份直接提交给EAR/IF计划的报告，并通过电子分发和在GEON网站（geongrid.org）上提供给地质界

0549324OldowThis grant will support an Earth sciences community workshop to identify ground-based digital acquisition, analysis, and visualization needs of the geological science community. A two workshop will be organized under the direction of John Oldow at the University of Idaho and is planned for early Winter, 2006. A current challenge for many geoscientists is access and training in the use of digital field mapping tools as well as the intricacies of merging digital datasets acquired at differing resolutions and using multiple tools. The development of user-friendly, open source software for processing and analysis of digital mapping products is a clear need and a considerable challenge. The workshop will focus on the possible development of a new facility/services to support state-of-the-art digital geologic field mapping using technologies including terrestrial laser scanning (TLS), GPS, digital photogrammetry, and remotely sensed imagery (e.g., satellite or airborne multispectral imagery), as well as more traditional field mapping tools. The facility concept has been termed INTERFACE (INTERdisciplinary Alliance for Digital Field Data ACquisition and Exploration) and would provide equipment, training, data processing, data archiving, and visualization facilities to researchers and students across the United States to support direct digital data acquisition and visualization of surficial landforms. Specific goals of the workshop are to: (1) identify the methods and technologies needed for digital data acquisition, (2) to explore database and analysis tool requirements, (3) outline a vision for the architecture of national system for equipment accessibility, training, analysis, and data archiving, (4) initiate a discussion on data standards, required metadata, and information formats for databases, (5) identify the visualization requirements associated with digital acquisition methods, (6) develop a strategy for community involvement and implementation of the digital acquisition system, and (7) outline the relation of the digital acquisition system to existing or planned cyberinfrastructural initiatives in the earth sciences. Attendance of about 25 earth scientists representing a wide range of expertise is planned. Participants will be drawn from the geomorphology, structure, seismic and geodetic communities, with targeted invitations to those with experience in digital acquisition, database development, information management, and the application of data analysis tools. The findings of the workshop will be presented to the geologic community at the 2006 National Meeting of the Geological Society of America and the Fall Meeting of the American Geophysical Union in addition to a report submitted directly to the EAR/IF Program and available to the community via electronic distribution and access on the GEON website (geongrid.org).***
