Why we

Logical Limit Consulting LLP (LLC) is a niche geospatial and water resources consultancy specializing in advanced surveying, hydrological modeling, and geospatial analytics for sustainable development across Urban, Water, and Climate Resilience domains. Founded on the principles of quality, innovation, and technical excellence, LLC leverages cutting-edge tools and domain expertise to deliver scientifically accurate and policy-relevant solutions.

LLC has established itself as a trusted leader in conducting high-resolution Drone Surveys using LiDAR, RTK-based Photogrammetry and Bathymetry specifically designed for topographic mapping, reservoir capacity estimation, flood risk modelling,  dam safety inspections, hydraulic structure assessment, river cross-sectioning, and dam reservoir monitoring. Our UAV / Drone -based inspection services are tailored for structural condition assessment of dams, barrages, canals, and associated assets using thermal imaging, photogrammetric 3D modeling, and automated defect detection workflows. This helps in capturing both thermal and high-resolution visual data to support predictive maintenance and disaster preparedness.

In addition to field data acquisition, LLC offers deep capabilities in Mathematical and Hydrodynamic Modeling. Our portfolio includes:

• 1D/2D Flood Inundation Modeling using tools like HEC-RAS, MIKE FLOOD etc.
• Dam Break Analysis  & EAP aligned with CWC and BIS Guidelines, integrated with digital terrain models from drone surveys
• River Morphology and Sediment Transport Simulations
• Urban Flood Modeling & Drainage Network Simulations using SWMM, InfoWorks ICM, and custom Python workflows
• Scenario-based Flood Risk Mapping and Early Warning System (EWS) design

We specialize in the development of customized GIS Dashboards and Decision Support Systems (DSS) using ArcGIS Enterprise, ArcGIS Online, and Google Earth Engine, providing real-time visualization and analytics for Urban Planning, Integrated Water Resource Management (IWRM), and Climate Change Impact Assessment. These systems enable stakeholders to make informed decisions backed by spatial intelligence, dynamic datasets, and advanced geoprocessing workflows.

We build real-time GIS Dashboards and Decision Support Systems (DSS) using ArcGIS Enterprise, ArcGIS Online, and Google Earth Engine (GEE) to integrate data from remote sensing, IoT, and simulation models. These dashboards support dynamic visualization, climate impact analytics, rainfall-runoff modeling, infrastructure stress analysis, and spatial planning — empowering government and engineering stakeholders for resilient urban and basin-scale planning.

• Drone-based Topographic Surveys (Photogrammetry & LiDAR).
• Bathymetric Surveys for Reservoir & River Capacity Assessment.
• DGPS & Static Control Point Surveys for geodetic referencing.
• Flood Inundation & Dam Break Analysis using industry-standard hydrodynamic models.
