Frequently Asked Questions
Common questions about our surveying services
How quickly can you deliver a survey quotation?
We deliver quotations on the same day for most standard projects. Once you share your project location, area coverage, and type of survey required via WhatsApp or our enquiry form - our team prepares a detailed quotation within hours. Complex multi-technology projects may require one business day.
Which states / regions do you cover in India?
Trishunya operates PAN INDIA. We have offices in Bhavnagar (Gujarat HQ), Delhi NCR, Ahmedabad, and Surat, allowing us to mobilize rapidly to any state. We have successfully executed projects in Gujarat, Rajasthan, Maharashtra, Madhya Pradesh, Uttar Pradesh, Delhi, Haryana, and more.
What accuracy does your DGPS / RTK survey achieve?
Our DGPS/RTK equipment achieves centimeter-level horizontal accuracy (±1–3 cm RMS) and ±2–5 cm vertical accuracy under open-sky conditions. For Total Station work, we achieve sub-centimeter accuracy. All control points use network RTK corrections or post-processed baseline adjustments.
How does Bathymetric / Underwater survey work?
We use Single Beam Echo Sounder (SBES) Sonar mounted on a survey boat with integrated DGPS positioning to map the underwater bed profile of rivers, canals, ponds, lakes, and reservoirs. The system records depth at every GPS position, producing underwater contour drawings, capacity calculations, silt volume estimates, and L/S profile sheets.
What data formats and deliverables do you provide?
Drone surveys: GeoTIFF DEM/DTM/Orthomosaics, LAS/LAZ point clouds (LiDAR), AutoCAD DWG drawings. DGPS/Total Station: DWG/DXF drawings and coordinate CSV sheets. Bathymetry: depth contour drawings and volume reports. GPR: scan reports and subsurface drawings. We also provide KMZ/GeoJSON layers for GIS integration.
Do you work with government / PSU clients?
Yes. We have experience working with government bodies, PSUs, and large EPC contractors across power transmission, irrigation, road, railway, and solar sectors. We are familiar with regulatory requirements, quality documentation standards, and reporting formats expected by government and infrastructure clients.
How long does a typical drone survey take?
For a typical 5–10 km² area, field data acquisition takes 1-2 days. For linear corridor surveys (e.g., 50 km transmission line), our teams cover 15–20 km/day. Data processing and delivery of orthomosaic/DEM/DWG outputs typically takes 3–5 working days after field work.
What is Ground Penetrating Radar (GPR) used for?
GPR is used for non-destructive detection of underground utilities, voids, rebar inside concrete, and subsurface anomalies — without excavation. Common applications: utility mapping before road/pipeline construction, detecting hidden rebar and post-tension cables in bridges/buildings, locating underground tanks or voids, and pavement layer thickness analysis.
