基本信息

项目摘要

Here, we propose a web-based, open-access, digital resource introduced here as the Digital Integrated Stratigraphy Project (DISP). The premise behind the DISP is to eliminate stratigraphic ambiguity associated with sample position within a stratigraphic section. For example, it is often difficult to compare one author’s measured section and data against another author’s geographically identical measured section and data as there are often discrepancies in the thicknesses of units, the assignments of litho- and chronostratigraphic terms, and/or the precise line of measured sections between authors. The DISP will provide a solution to this problem by producing a precise digital rendering of the outcrop using LIDAR and overlain digital photography to produce a cm to mm-scale accurate digital version of a given outcrop globally referenced by global navigation satellite positioning (GNSS). Once available online as shown at www.utdallas.edu/igeology , where a series of digital outcrops in Oklahoma are accessible, researchers could access the program and digital models. We also have the means to log their sample positions online directly onto the digital outcrop using a methodology where a user could attribute on an outcrop model by working on the 2D images thus allowing unambiguous stratigraphic reference for future research. The proposed project will serve as a proof-of-concept for the DISP with a limited initial goal of addressing the six Silurian Global Boundary Stratotype Sections and Points (GSSPs) located within Wales and England.
在这里,我们提出了一个基于网络的、开放获取的数字资源,在这里被称为数字综合地层学项目(DISP)。DISP的前提是消除地层剖面中与样品位置相关的地层模糊性。例如,通常很难将一位作者的测量剖面和数据与另一位作者的地理位置相同的测量剖面和数据进行比较,因为在单元厚度、岩性和年代地层术语的分配和/或作者之间测量剖面的精确线方面经常存在差异。DISP将通过使用激光雷达和覆盖数字摄影生成露头的精确数字渲染来解决这一问题,从而在全球导航卫星定位(GNSS)的参考下生成给定露头的厘米到毫米尺度的精确数字版本。如www.utdallas.edu/igeology所示,一旦可以在网上获得,研究人员就可以访问俄克拉何马州的一系列数字露头,并访问该程序和数字模型。我们也有办法将他们的样本位置直接在线记录到数字露头上,使用一种方法,用户可以通过处理2D图像来确定露头模型,从而为未来的研究提供明确的地层参考。拟议的项目将作为DISP的概念验证,其有限的初始目标是解决位于威尔士和英格兰的六个志留系全球边界层型剖面和点(gssp)。
