Detailed ground survey for infrastructure, design, construction and development projects.
Explore CapabilityHydrographic / Bathymetric Survey
Rivers, canals and reservoirs surveyed with positioning and echo-sounding technology.
Explore CapabilityCorridor & Infrastructure Survey
Highway, railway, transmission line, canal and pipeline surveys for linear infrastructure.
Explore CapabilityPhotogrammetry & Point Cloud
Orthomosaics, terrain models, contours and classified point clouds processed in-house.
Explore CapabilityCAD / GIS & Mapping
Engineering-ready CAD drawings, GIS datasets, digital maps and geospatial deliverables.
Explore CapabilityGPR / Subsurface Survey
Non-destructive Ground Penetrating Radar investigation for buried utilities, structures and features.
Explore CapabilityGround Truthing & GCP Networks
DGPS validation of satellite imagery and ground control networks for mapping programmes.
Explore CapabilitySelected Projects
Representative BTPL assignments — what was required, how it was surveyed, and what was delivered.
Technology Behind Our Accuracy
Grouped by capability — the right sensor and method are selected per project, not the other way around.
Aerial Mapping
UAV mapping systems for efficient large-area data acquisition.
LiDAR Reality Capture
LiDAR systems for dense 3D measurement and terrain modelling.
GNSS Positioning
Professional GNSS/RTK technology for survey control and field observations.
Engineering Measurement
Total Stations, Digital Levels and associated field instrumentation.
Hydrographic Mapping
Positioning and echo-sounding systems for underwater terrain measurement.
Processing Capability
Photogrammetry, point-cloud, terrain and GIS processing workstations and software.
Industries We Serve
Survey and geospatial support across India's infrastructure and development sectors.
From Survey Data to Usable Deliverables
BTPL does not simply collect data — every project ends in information your engineers can use directly.
DSM ↔ DTM — See the Difference
Drag the divider: a Digital Surface Model includes vegetation and structures, the Digital Terrain Model is the processed bare-earth surface engineers design on. (Illustrative visual.)
