Service 01
Mapping & Surveying
Detailed base maps and spatial datasets — the foundation for planning urban layouts, infrastructure networks and zoning.
Our surveying toolkit spans drone surveys, LiDAR scanning, D-GPS and traditional ground survey, forming the base layer for infrastructure development, environmental impact assessment and 3D site visualisation.
- Topographic and contour mapping
- Base maps for zoning and master planning
- 3D site visualisation and terrain models
- Deliverables in DWG, KML, shapefile and GIS-ready formats
UAV · RGB + thermal
Service 02
Drone (UAV) Surveys
Rapid, high-resolution aerial data collection for 3D modelling, site analysis and infrastructure monitoring.
Drone-based LiDAR and thermal imaging improve precision on large or hard-to-access sites — deployed on projects across Mumbai and Himachal Pradesh.
- Photogrammetric orthomosaics and DSM/DTM generation
- Drone-mounted LiDAR for vegetated and steep terrain
- Thermal imaging for site and asset inspection
- Repeat flights for construction progress monitoring
Service 03
LiDAR Surveys
High-density point-cloud capture for accurate terrain modelling, vegetation mapping and infrastructure corridor planning.
Including hill-terrain projects executed in Sikkim and Mandi, Himachal Pradesh, where conventional survey access is difficult and ground crews cannot safely reach the slope.
- Bare-earth DTM extraction beneath vegetation canopy
- Corridor and alignment planning in steep terrain
- Classified point clouds (ground, vegetation, structures)
- Volume, slope and cross-section derivation

Service 04
Differential GPS (D-GPS) Surveys
High-accuracy RTK-GNSS positioning for land parcel mapping, infrastructure alignment, control point establishment and cadastral surveys.
D-GPS control also underpins our GPR utility surveys — ensuring every detected utility is tied to precise, mappable coordinates rather than a chalk mark on the road.
- Primary and secondary control point networks
- Cadastral and land parcel boundary survey
- Alignment staking and as-built verification
- Georeferencing of GPR, drone and LiDAR datasets
Service 05
Total Station Surveys
High-detail land surveys supporting urban design projects with accurate measurement for building layouts, road networks and utility placement.
Where a drone gives coverage, a total station gives detail — the two are routinely combined on the same site so that hard features are captured to survey-grade tolerance.
- Detail and plane-table survey for building layouts
- Road network and utility placement survey
- Setting out and construction layout support
SIR-4000 · 400 MHz
Service 06 · Flagship capability
Ground Penetrating Radar (GPR)
Non-invasive detection of subsurface utilities, pipelines and underground anomalies — critical for infrastructure planning ahead of excavation.
Using GSSI SIR-4000 systems with 400 MHz antennas, effective to roughly 5 m depth, our GPR surveys have supported metro and flyover projects by mapping utility corridors and flagging conflicts before construction begins.
| Control system | GSSI SIR-4000 |
|---|---|
| Antenna | 400 MHz |
| Effective depth | ~5 m, site conditions permitting |
| Positioning | DGPS-marked anomalies, cross-checked on site |
| Processing | RADAN-7, exported to GIS |
Service 07
Remote Sensing & GIS
Comprehensive spatial analysis using satellite and aerial imagery to assess land use, monitor environmental change and support infrastructure and resource-allocation decisions.
GIS layers give planners a decision-ready view of the terrain — not a folder of raw imagery, but classified, attributed data that answers the question that was asked.
- Land use / land cover classification and change detection
- Multi-year time-series analysis of site conditions
- Vegetation and tree-cover mapping, including deep-learning detection
- Spatial datasets delivered as KML, shapefile or geodatabase
Strata interpretation
Service 08
Geological & Geotechnical Investigations
Subsurface geological assessments that inform safe, cost-effective construction practices.
Especially valuable in urban and hill areas prone to geological challenges such as slope instability or highly variable ground conditions, where a generic assumption about the subsurface is an expensive thing to get wrong.
- Site characterisation for foundation and earthworks design
- Slope stability assessment and modelling (Rocscience)
- Structural analysis of existing buildings
- Geotechnical investigation reporting
Service 09
Urban Planning & Development Support
We integrate geospatial analysis with urban growth strategies — modelling growth, analysing land suitability, and contributing to master plans and infrastructure blueprints.
The aim is straightforward: sustainable, resilient communities planned on evidence about the land rather than on assumption.
- Land suitability and constraint analysis
- Growth modelling and scenario mapping
- Master plan and infrastructure blueprint inputs

Common questions
Before you brief us
How deep can GPR actually detect?
With a 400 MHz antenna on the GSSI SIR-4000, effective detection is around 5 m, though real depth depends heavily on ground conditions — moist clay attenuates the signal far more than dry sand or compacted fill. We confirm achievable depth on site during the calibration pass and tell you if the scope needs adjusting.
What formats do you deliver in?
Reports as PDF, drawings as DWG, and spatial data as KML, shapefile or geodatabase — whatever plugs into your design workflow. We agree the deliverable format at scoping so nothing has to be reworked at handover.
Can you work in remote or hill terrain?
Yes. LiDAR and drone survey exist precisely for sites where ground crews cannot safely or economically reach the slope — we have executed terrain mapping in Sikkim and Mandi, and survey work on an international dam project in Afghanistan.
Do you combine several services on one site?
Routinely — and it is usually the cheaper route. A typical corridor scope combines D-GPS control, GPR utility detection and drone topographic capture in a single mobilisation, with one set of coordinates tying all three datasets together.
How quickly can you mobilise?
It depends on site location, permissions and the instrument package required. Send us the scope and location and we will confirm a realistic mobilisation window with the quotation.

Not sure which service you need?
Describe the problem — a corridor to clear, a slope to model, a parcel to map — and we’ll tell you which method answers it, and what it costs.
