Lineaments as a tool for decision-making in the optimal location of boreholes in the base zone: Case of the department of Abtouyour (republic of Chad)

This study has made it possible to highlight that the extraction of structural lineaments helps in optimal decision-making implantation boreholes basement zone. For this purpose, we used remote sensing, as a complementary tool and validated our results with drillings carried out using electrical tomography area. semi-automatic method allowed us understand importance sensing can play establishment successful drilling software such Excel for data ARMAP 10.8 GIS, PCI Geomatica lineaments. The orientation was obtained rose diagram ROCKWORKS software. In addition, images from Landsat 9+, ASTER, DEM, STRM 30m resolution which develop thematic maps. Thus were able validate Works representation by profiles resistivity especially area according extracted. combination different parameters middle GIS facilitated spatial analysis, good decision making drill water well approach more than 53% positive intercepts while only 13% negative
