Mapping lineament features using GIS approaches: case study of Neoproterozoic basement rocks in the South-Eastern Desert of Egypt

Abstract

In geosciences, field observations, and survey, remote sensing applications and data analysis still need to find out a seamless approach of integration, interlinking, and storing environment. Most applications of geomatic tools in geological studies (mainly in southern countries) focus on getting information of the real world from satellite data, but do not specify the concept of the way to represent them. However, heterogeneity exists in data form of different geological components (e.g., petrography and structure analysis), measurements, spatial analysis, and classification, which make the property and relation in the perspective of integration and management non-trivial aspect. However, this paper is an attempt to figure out a geo-data management approach by using the geo-information system (GIS). The case study is South Eastern Desert, Egypt, which built up of Neoproterozoic basement rocks and experienced successive deformations. We proposed to capture different geological data and processed digital images, together with conceptual model, to facilitate a geo-spatial framework and improve the exploration and detection of lithologies, lineaments features, and find out its interlink. Therefore, the lineament number percentage and the lineament length percentage could be used as significance of rock unit chronology, where the digital foot prints of Neoproterozoic basement rocks were created.
