About CartoXR

Where Geospatial Science Meets Immersive Technology

CartoXR pioneers the fusion of Geoinformatics and Extended Reality (XR). Founded by researchers and practitioners, we design and deliver rigorous geospatial solutions — from satellite-driven climate analysis and UAV flood mapping to AR/VR spatial visualization — for government, industry, and academia.

Based in Chennai with project experience across India and presented at international forums including ISPRS Perth 2024, we bring both research depth and delivery capability to every engagement.

What We Do

End-to-End Geospatial Services

From raw satellite imagery to immersive decision environments — we handle the full analytical pipeline.

🛰️
Satellite Image Analysis
Multi-temporal analysis using Sentinel-1/2, Landsat, MODIS. Land use change detection, vegetation indices (NDVI/EVI), land surface temperature, and spectral classification for climate monitoring.
🌊
Flood Risk & Hydrological Modelling
State-scale inundation mapping, flood extent delineation using SAR imagery, DEM-based drainage analysis, and disaster risk zoning for governments and insurers.
🌡️
Climate & Environmental Monitoring
Urban heat island mapping, air quality analysis via GEE, groundwater-LST interaction studies, and carbon stock assessment using optical and thermal remote sensing.
🚁
UAV Survey & Precision Mapping
High-resolution photogrammetry, 3D point cloud generation, orthomosaic production, and rapid deployment for emergency response and infrastructure inspection.
🥽
XR-based Spatial Visualization
AR/VR environments for geospatial decision-making — volumetric 3D model assessment inside VR, digital twin navigation, and immersive training simulations for field teams.
🎓
Capacity Building & Workshops
QGIS, Google Earth Engine, and XR training for government officials, urban planners, researchers, and academic institutions across India.
