Geographic information system

Essential India provides advanced, data-driven solutions for managing critical infrastructure, environmental hazards, and sustainability challenges. Our expertise is rooted in fusing cutting-edge geospatial technology with deep domain knowledge in civil engineering, hydrology, and environmental policy.

We leverage high-resolution techniques including Drone/UAV-based image acquisition, LiDAR, and photogrammetryto achieve unparalleled spatial accuracy. Our 3D models and site topographies reach a ground sampling resolution of 2 cm, enabling the analysis of all physical features larger than 2 cm for precise mapping and volumetric calculations.

We deliver unparalleled precision in structural and urban analysis using our proprietary 3D Building Stock Model:

• Ultra-High Resolution: Models are created using Drone/UAV-based image acquisition and advanced photogrammetry techniques.
• 2 cm Accuracy: We achieve a ground sampling resolution of 2 cm, allowing for detailed reconstruction of built forms. All physical features larger than 2 cm can be accurately measured and analyzed.
• Comprehensive Outputs: Ideal for precise mapping, volumetric calculations, and detailed structural assessments.
• Specific Analysis: Includes modeling to capture openings and ventilation among built forms. We also conduct Rapid Visual Screening (RVS) using instrument-based surveys and thermal mapping.

RWe provide comprehensive risk assessment and planning to mitigate environmental hazards:

• Comprehensive Modeling: Our focus includes hydrology and hydrodynamic modeling for flood mapping, simulation, and comprehensive risk assessment.
• Integrated Technology: Our investigation utilizes drone and satellite-based data, leveraging GIS, LiDAR, and photogrammetry techniques.
• Software Foundation: Analysis is built on industry-standard tools such as Hec Ras, Hec HMS, SWAT, and open-source GIS.
• Methodology: We conduct critical analyses including:
  
  • Rainfall to Runoff Scenario
  • Assessment of Impervious Surfaces
  • Proximity Mapping & Modelling
  • Flow Direction >> Accumulation
  • Determining the Longest Path, Reach etc.

We support sustainable planning and infrastructure safety by integrating above-ground data with subsurface information:

• We incorporate Subsurface soil/Geological Information obtained through ERT Profiling into our analysis.

Our capabilities are supported by a strong foundation of global and local experts:

• Local Strength: We partner with Oyeta, an MSME with a pool of Architects, Civil & Structural Engineers, and MEP Engineers with a combined strength of 20+ Associates and employees.
• Global Sustainability Leadership: Our team includes Dr. Glenn Frommer, a pioneer in the sustainability and environmental movement with over 30 years of experience. He was involved in drafting the GRI G3.1 and G4 guidelines and other global standards (AA1000AS, BSI-8900, ISO-26000).
• Digital Finance Solutions: We collaborate with ApS (headquartered in Denmark), a Sustainable Management Consultant and creator of digital platform solutions for Sustainable Impact Investing and Green Financing.
