LANDMASS

This dataset was developed at the School of Electrical and Computer Engineering (ECE) at the Georgia Institute of Technology as part of the ongoing activities at the Center for Energy and Geo-Processing (CeGP) at Georgia Tech and KFUPM. LANDMASS stands for “LArge North-Sea Dataset of Migrated Aggregated Seismic Structures”. This dataset was extracted from the North Sea F3 block under the Creative Commons license (CC BY-SA 3.0). For the purposes of this work, four classes of seismic structures: Horizons, Chaotics, Faults, and Salt Domes, were automatically extracted from the F3 block using a curvelet based distance measure for seismic images also proposed by the CeGP. Then the extracted images where manually verified and all outliers or images that had more than one structure were removed.

本数据集由佐治亚理工学院电气与计算机工程学院（School of Electrical and Computer Engineering, ECE）开发，作为佐治亚理工学院能源与地质处理中心（Center for Energy and Geo-Processing, CeGP）与KFUPM联合推进的在研项目的一部分。LANDMASS意为“大型北海偏移聚集地震构造数据集（LArge North-Sea Dataset of Migrated Aggregated Seismic Structures）”。本数据集基于知识共享署名-相同方式共享3.0许可（Creative Commons license, CC BY-SA 3.0），源自北海F3区块。为满足本次研究需求，研究团队采用CeGP提出的基于曲波（Curvelet）的地震图像距离度量方法，从F3区块中自动提取了四类地震构造：层位（Horizons）、混沌构造（Chaotics）、断层（Faults）与盐丘（Salt Domes）的对应图像。随后对提取得到的图像开展人工校验，剔除所有异常样本以及包含多种构造的图像。
