Data Mosaic Web Application

Data Mosaic is an advanced software solution which gives the exploration or mine geologist the ability to rapidly and accurately turn numerical drill hole data into useful geological information.\n\n## Rapid and consistent interpretation\nUsing automated methods, Data Mosaic provides consistent interpretation of numerical drill hole data, overcoming inconsistent subjectivity inherent in human interpretation of large and complex data sets.\nData Mosaic can process large data sets in a matter of seconds or minutes, replacing human interpretation, which may take many weeks. \nIt uses an automated process controlled by the geologist so that their expert geological knowledge is incorporated into the \nworkflow, resulting in geologically meaningful outputs targeted to solving deposit specific problems.\n\n## Accurate lithological boundary detection\nData Mosaic uses boundary detection algorithms adapted from established and reliable image analysis techniques; these provide accurate detection of lithological boundaries down hole. \nThe boundaries are used to segment the data stream into lithological units to which lithological classification is applied. This method overcomes noise and misclassification problems that result from applying machine learning to individual samples.\nLineage: Data Mosaic is a variant on the "Wavelet Tessellation" (WT) method developed as part of the Deep Exploration Technologies (DET) CRC. The DET CRC assigned commercialisation rights for WT to their sponsor Imdex for inclusion in Imdex's IOGas software product.\n\nData Mosaic differs from WT in that (1) it has multivariate capabilities, while WT is for univariate data only and (2) scale in Data Mosaic is measured using wavelet coefficient, while scale in WT is measured using wavelet scale. The development of Data Mosaic was wholly funded by CSIRO.\n\nThe methods behind Data Mosaic and WT have been published but code has not been made public.\n\nThe Data Mosaic name is a registered trademark belonging to CSIRO.\n

Data Mosaic是一款先进的软件系统，可助力勘探与矿山地质学家快速、精准地将数值化钻孔数据转化为具有实用价值的地质信息。

## 快速且一致的解译
借助自动化手段，Data Mosaic可对数值化钻孔数据实现标准化解译，克服了人工解译大型复杂数据集时固有的主观不一致性问题。Data Mosaic可在数秒至数分钟内完成大型数据集的处理，替代需耗时数周的人工解译流程。该软件采用由地质学家管控的自动化处理流程，可将专家的地质专业知识融入工作流，最终生成针对特定矿床问题的具有地质意义的输出结果。

## 精准岩性边界识别
Data Mosaic采用源自成熟可靠图像分析技术的边界检测算法，可精准识别钻孔内的岩性边界。此类边界可将数据流分割为多个岩性单元，并对其开展岩性分类。该方法可规避因对单一样本应用机器学习而引发的噪声干扰与分类错误问题。

## 技术溯源
Data Mosaic是“小波镶嵌（Wavelet Tessellation，WT）”方法的衍生变体，该方法作为深部勘探技术合作研究中心（Deep Exploration Technologies CRC, DET CRC）的研发成果之一推出。DET CRC已将WT的商业化授权授予其赞助方Imdex，以便将其集成至Imdex的IOGas软件产品中。

Data Mosaic与WT的差异主要体现在两点：其一，Data Mosaic具备多变量处理能力，而WT仅支持单变量数据；其二，Data Mosaic的尺度通过小波系数进行度量，而WT的尺度则基于小波尺度计算。Data Mosaic的研发工作全额由澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation, CSIRO）资助。

目前，Data Mosaic与WT的核心技术方法已公开发表，但相关代码尚未对外公开。
