Explore CapabilitySelected Projects
Representative BTPL assignments — what was required, how it was surveyed, and what was delivered.
Which survey technologies does BTPL use?
BTPL uses survey-grade mapping UAVs, drone LiDAR sensors, multi-frequency GNSS receivers for static control and RTK measurement, total stations and digital levels, and echo-sounding hydrographic systems, processed in-house — the 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.
What deliverables does BTPL produce?
BTPL delivers orthomosaics, digital terrain and surface models, contours, classified point clouds, CAD topographical drawings, GIS data, cross sections, longitudinal profiles, volume analysis, bathymetric surfaces, KML/KMZ files and technical reports with methodology and QC records — every project ends in information engineers can use directly.
What is the difference between a DSM and a DTM?
A Digital Surface Model (DSM) records the top of everything a sensor sees — ground, vegetation, buildings and structures — while a Digital Terrain Model (DTM) is the processed bare-earth surface with vegetation and structures removed, and it is the surface engineers design on. BTPL delivers both from UAV and LiDAR campaigns. Drag the divider to compare the two. (Illustrative visual.)
