Nine disciplines. One control point behind all of them.

Survey, mapping and land-management work, run on a single accuracy standard from the first GCP to the final report.

Integrated Land Audit

One verified view of every plot.

Development schemes often carry gaps between what was approved, acquired, possessed and what actually exists on the ground. We combine revenue records, layout plans, DGPS survey, drone imagery, LiDAR, GIS and field verification into a single Digital Land Asset Database.

Approved, acquired and possession area
Actual physical area on the ground
Plot-wise discrepancies and encroachments
Vacant land and development status

DGPS / GNSS Survey

Precise positioning, the base of every map.

Dual-frequency GNSS/DGPS receivers with RTK and NTRIP positioning deliver survey-grade coordinates for every control point.

Ground Control Points (GCPs)
Geo-referencing of revenue maps and layout plans
Coordinate conversion and transformation
High-accuracy boundary and parcel surveys
[If offered] Boundary demarcation and total station surveys

Drone / UAV Survey

Large areas mapped quickly, with survey-grade accuracy.

RTK/PPK-enabled drones, flown by [DGCA-certified pilots — confirm], capture high-resolution imagery processed into accurate maps and models.

Aerial photogrammetry and high-resolution imagery
Orthomosaic generation
Digital Elevation Model (DEM) and Digital Terrain Model (DTM)
3D reconstruction and volumetric analysis
Large-area land and infrastructure mapping

LiDAR Survey

High-precision reality capture for land, buildings, infrastructure and corridors.

LiDAR captures dense 3D point clouds, even under vegetation and in complex spaces, geo-referenced with RTK/GNSS and ground control points.

3D laser scanning — buildings, industrial facilities, heritage structures, interiors and exteriors
Mobile / handheld LiDAR — rapid site scans, indoor mapping, obstructed areas, as-built records
Drone LiDAR — large terrain, vegetated and inaccessible areas, corridors
LiDAR topography — ground surface, contours, DEM/DTM, breaklines, spot levels, terrain classification
Roads & infrastructure — carriageway, drainage, bridges, flyovers, utility corridors, as-built surveys
Volume & change analysis — earthwork, stockpiles, cut and fill, construction progress
