AI Insight
This study integrates open-source scripting tools, specifically GMT, R, and QGIS, to produce 12 thematic maps synthesizing geological, geophysical, geomorphological, and gravimetric data for Pakistan. The work applies automated cartography and geoinformatics methods to analyze spatial relationships between Earth's gravity fields, tectonic activity, and geological evolution, with particular focus on the Sulaiman Fold Belt and Muslim Bagh Ophiolite Complex. The authors present a reproducible, step-by-step scripting workflow using open datasets such as GEBCO and EGM-2008 to enable high-resolution cartographic visualization of a geologically complex region.
Why it matters
The methodology and resulting maps can support geological hazard assessment, tectonic research, and resource exploration in Pakistan by providing freely reproducible, high-resolution geospatial products. The open-source scripting approach also offers a transferable framework applicable to other geologically complex regions worldwide.

Abstract: Along with the development of the scripting technology in cartography, such as the GMT and libraries of R programming language, geologic and geophysical mapping is being vigorously promoted, where the integration of the thematic data, such as GEBCO, EGM-2008 and geological raster and vector layers is one of the primary datasets that provides the high-resolution raw sources for cartographic visualization in the geologically complex regions like Pakistan. This study aims to integrate scripting methods of automated cartography, methods of applied geoinformatics for geomorphometric analysis and technical data processing (formatting, projecting, plotting), to provide a synthesis of the geological, geophysical and geomorphological maps of Pakistan they as new information supporting analysis of the geospatial variations of geology, geomorphology, tectonics and gravity fields with a special focus on the geologically remarkable region of Pakistan: Sulaiman Fold Belt and Muslim Bagh ophiolite complex. This study presents new 12 thematic maps, which are technically made using scripting approaches and open tools. All maps cover the region of Pakistan and they are made using open source tools: GMT, R and QGIS. A GMT and R based scripting mapping is applied for mapping Pakistan, and its algorithm steps are presented stepwise as code snippets. A system complex approach of the data integration and formats reshaping, data conversion and reformatting for a single project of the geology of Pakistan is designed and developed based on the combination of the programming and scripting techniques and with additional mapping, which integrates the geospatial datasets. Correlation between spatial phenomena of Earth’s gravity, geologic evolution and tectonic movements were commented.
