Lineament mapping
Nettet30. mar. 2024 · The main aim of the present study is to investigate geochemical analysis of iron ore and iron-enriched mineralised zones and their source identification by understanding lithological, structural and geomorphological units. The geology, geomorphology and lineament maps were prepared with help of Landsat 8 OLI … NettetMETHODS ™ software for editing. ArcView 3.0b™ software was used to create the lineament map displayed in figure 4. A similar approach was used to create the geologic map in figure 3. The geologic unit boundaries apparent on the SLAR swaths were mapped and then compared to previous geologic maps of Puerto Rico at various scales. A …

Successfully extract Lineament and … NettetA remote sensed lineament map was produced using two different methods: (i) application of directional filters and edge enhancement; and (ii) data fusion of ETM+ with SAR image. The selective PC analysis of ETM+ using bands 1, 3, 4, and 5 was used in mapping iron and iron oxide bearing minerals.
Nettet1. feb. 2016 · Lineament features were mapped in, visible bands from ASTER and DIP product derived from Landsat ETM+ Images as well as in a LiDAR (2m) DEM. Lineaments of geological origin were identified within the karstic areas and possibly are correlated to discharge areas. Several types of images are necessary to make a more accurate … NettetA lineament is a linear feature in a landscape which is an expression of an underlying geological structure such as a fault. Typically a lineament will appear as a fault-aligned …
