Mapping Every
Axis. X. Y. Z.

A drone survey uses UAVs/Drones equipped with high-resolution cameras, LiDAR sensors, or thermal imagers to capture georeferenced aerial data. The data is processed into deliverables like orthomosaic maps, 3D point clouds, digital terrain models (DTM), and digital surface models (DSM) with centimetre-level accuracy. Axesmap delivers 2.5cm - 3cm ground sample distance (GSD) with survey-grade cameras covering 1,000+ acres per day.

Professional drone surveys achieve ±5–10 cm horizontal (XY) accuracy and ±15–20 cm vertical (Z) accuracy with ground control points (GCPs). This is comparable to traditional surveys but covers vastly larger areas in a fraction of the time. For projects requiring higher precision, we use RTK/PPK-enabled GPS for real-time corrections.

Yes. Drone surveys are fully legal under DGCA Drone Rules 2021. Operators must hold a Remote Pilot Certificate (RPC), register drones on the Digital Sky Platform with a Unique Identification Number (UIN), and operate within designated green/yellow airspace zones. All Axesmap pilots are DGCA-certified and documented.

Drone survey costs in India typically range from ₹500 to ₹3,000 per acre, depending on the survey type (RGB, LiDAR, or thermal), area size, terrain complexity, and required deliverables. A basic RGB orthomosaic survey of 100 acres may cost ₹30,000–₹60,000, while LiDAR surveys cost more due to specialized equipment. Contact Axesmap for a detailed project-specific quotation.

Field data collection (including GCPs) for a typical 100-acre site takes 1–2 days depending upon terrain and nature od vegetation. Data processing and deliverable preparation takes an additional 3–7 working days depending on complexity. Axesmap can cover 1,000+ acres per day with our survey-grade drones, making large-area projects significantly faster than traditional surveying methods.

Standard deliverables include orthomosaic maps (georeferenced 2D imagery), Digital Terrain Model (DTM), Digital Surface Model (DSM), contour maps, 3D point clouds, volume calculations, and cross-section profiles. All data is delivered in industry-standard formats — GeoTIFF, LAS, DXF, SHP, KML — compatible with GIS software (QGIS, ArcGIS) and CAD platforms (AutoCAD, Civil 3D).

Axesmap offers six core services: RGB aerial survey (2.5cm -3cm GSD orthomosaics and DTM/DSM), aerial LiDAR (dense 3D point clouds for vegetation-penetrating terrain data), thermal imaging (radiometric dual-sensor capture for solar and infrastructure inspection), land survey and volumetrics (cut-fill analysis, stockpile estimation, contour profiling), 3D documentation (photogrammetric heritage and asset capture in OBJ/FBX/GLB), and construction monitoring with AI-powered geospatial analytics dashboards.

Axesmap is headquartered in Bengaluru but operates pan-India. We have mobilisation capability across all Indian states and have completed projects for clients including Indian Railways, NHAI Projects, BBMP, BDA, Mines and Geology Departments and major private companies across multiple states and terrain types — from coastal plains to mountainous regions.

We serve infrastructure (railways, highways, bridges), real estate and construction, mining and quarrying, energy (solar plant inspection, transmission corridors), agriculture, urban planning (smart city surveys for BBMP/BDA), and heritage/archaeology (3D documentation of historical sites and monuments across India).

Photogrammetry uses overlapping high-resolution photographs to create 2D maps and 3D models — ideal for open terrain, construction sites, and urban areas. LiDAR uses laser pulses that penetrate vegetation canopy to capture true ground elevation — essential for forested areas, corridor mapping, and flood analysis. Axesmap offers both technologies and recommends the best approach based on your terrain and project requirements.

GSD (Ground Sample Distance) is the real-world size each pixel represents in your aerial image. Axesmap achieves 2.5 cm - 3 cm GSD, meaning each pixel covers 2.5 cm on the ground. Lower GSD means higher detail — critical for engineering-grade surveys, construction monitoring, and precise area and volume calculations where centimetre-level measurement matters.

Yes. For hilly terrain, we use terrain-following flight paths that maintain consistent altitude above ground level for uniform GSD. For dense forest or vegetation, we deploy LiDAR sensors whose laser pulses penetrate canopy to capture true ground surface data — something RGB cameras cannot do. This makes drone surveys effective in areas where traditional survey crews cannot safely or practically access.
