Remote Sensing in Geological Mapping
Research Guide
What is Remote Sensing in Geological Mapping?
Remote Sensing in Geological Mapping uses multispectral, hyperspectral, and LiDAR data to identify lithological units and map geological structures over large areas.
This subtopic integrates satellite imagery and airborne sensors with GIS for terrain analysis and mineral exploration. Machine learning enhances classification accuracy on hyperspectral datasets (Hoffmann and Sander, 2006). Over 50 papers since 2000 address data fusion for structural mapping, with key works cited over 300 times.
Why It Matters
Remote sensing enables cost-effective mapping of inaccessible terrains for mineral prospecting and landslide hazard assessment. Enge et al. (2007) workflow from outcrop data to 3D models supports reservoir simulation, cited 178 times for petroleum exploration. Abbaszadeh Shahri et al. (2023) hybrid deep learning generates 3D geo-models from multisource data including remote sensing, aiding emergency management with 78 citations. Kutzner et al. (2020) CityGML 3.0 integrates remote sensing for urban geological modeling, impacting infrastructure planning (188 citations).
Key Research Challenges
Spectral Confusion in Lithology
Multispectral data often confuses similar rock types due to overlapping signatures. Hoffmann and Sander (2006) highlight this in hydrogeology mapping with 59 citations. Machine learning classifiers struggle without hyperspectral augmentation.
Topographic Correction Variability
LiDAR integration requires precise DEM corrections for rugged terrain. Enge et al. (2007) note data capture challenges in outcrop-to-model workflows (178 citations). Shadow effects degrade structural lineament detection.
Scalable 3D Model Uncertainty
Fusing remote sensing with borehole data propagates errors in 3D geological models. Abbaszadeh Shahri et al. (2023) address uncertainty in deep learning geo-models (78 citations). Validation lacks ground truth in remote areas.
