As a result, a new lineament map was produced that represents the subsurface geological features and structures using visual interpretation and digital image processing by utilizing different enhancement techniques. Digital image processing techniques for detecting surface alteration - An application on the Alaska Peninsula: A section in The United States Geological. A special attention has been given in this study to the textural analysis techniques and the methods of image enhancements of Landsat (ETM+) images. This area was chosen for conducting a study based on satellite imagery interpretation of Landsat Thematic Mapper (ETM+). The study area is becoming an important target for geological survey activities, mineral exploration and industrial investment. ![]() The aim of this study is to utilize remote sensed data and digital image processing techniques for updating the structural map in the north eastern part of the Dead Sea (Ma’in area), Jordan.

Virtually cloud-free Landsat coverage was used, but to be detected, the alteration area must also be unobscured by vegetation. The techniques used here are useful for mapping deposits that have exposed surface alteration of at least an hectare, the approximate spatial resolution of the Landsat data. Digital image processing techniques were used for mapping structural features using a medium resolution image (ETM+) from Landsat 7. This study focuses on using Landsat multispectral scanner data for the Port Moller, Stepovak Bay, and Simeon of Island Quadrangles to detect surface alteration, probably limonitic (iron oxide staining) and(or) argillic (secondary clay minerals) in character, that could be indicative of mineral deposits. However, because of problems associated with remoteness and poor weather, little detailed mineral exploration work has been carried on there. The tectonic evolution of the Alaska Peninsula makes it a likely area for the discovery of significant mineral deposits. ![]()
