Storage Of Geological Data Research Articles

Geological Publication Media and Data Preservation

Computers and their uses quickly were adapted in the latter half of the 20th Century ushering in the Information Age. The recording and storage of geological data, the analysis of those data, and communicating the results have generated some major problems that have changed the publication venue. Data storage has gone through a series of devices and procedures in their use including from paper tape, punched cards, magnetic tape, cassettes, microfiche, softstrip, diskettes, and CDs to DVDs and flash drives. Communication is almost instantaneous via e-mail and many publications now are issued only as softcopy on the Internet. Preservation of information therefore is of concern with the disappearance of hardcopy. All of this is possible because the speed of processing has increased by a factor of millions and storage capacity also has increased by the same magnitude. The amount of data and results available is staggering, and locating what is needed and important in this fast moving age is one of the most important aspects of this revolution.

A methodology for 3D modeling and visualization of geological objects

Geological body structure is the product of the geological evolution in the time dimension, which is presented in 3D configuration in the natural world. However, many geologists still record and process their geological data using the 2D or 1D pattern, which results in the loss of a large quantity of spatial data. One of the reasons is that the current methods have limitations on how to express underground geological objects. To analyze and interpret geological models, we present a layer data model to organize different kinds of geological datasets. The data model implemented the unification expression and storage of geological data and geometric models. In addition, it is a method for visualizing large-scaled geological datasets through building multi-resolution geological models rapidly, which can meet the demand of the operation, analysis, and interpretation of 3D geological objects. It proves that our methodology is competent for 3D modeling and self-adaptive visualization of large geological objects and it is a good way to solve the problem of integration and share of geological spatial data.

The Planning of, and Initial Operations at, the Arnot Colliery Opencast Strip Mine

Synopsis This paper on coal mining at Arnot briefly reviews the operations at the colliery with reference to the original concept of an underground operation. The reasons for a change to strip mining for a large proportion of the output are discussed and details are given of the layout and operation of a strip mine with specific reference to Arnot, and the particular equipment selected for the operation. Reference is made to the computer based system for the storage of geological data in the Anglo American Corporation and the further development of this system as a planning aid in the strip mine.
