Land Survey

Aruna Technology provides land surveying and aerial mapping services for infrastructure, water resources, mining and property development across Cambodia. We combine GNSS and total station surveys with UAV imagery, LiDAR and GIS to provide the terrain data, maps and drawings needed for planning, engineering design and land management.

Our teams work from individual development sites to large irrigation schemes and mining areas. We establish survey control, measure terrain and existing infrastructure, and prepare outputs that clients can use directly in CAD and GIS applications.

Our survey services

  • Control surveys: Establishment of benchmarks and ground control points connected to the national survey network.
  • Topographic and engineering surveys: Site surveys, levels, longitudinal profiles, cross-sections and detailed surveys of roads, canals, drainage and hydraulic structures.
  • UAV and LiDAR surveys: Aerial data capture and processing to produce orthophotos, elevation models, contours and topographic maps.
  • Bathymetric surveys: Riverbed and channel surveys to support hydraulic modelling and infrastructure design.
  • Land measurement and boundary surveys: Measurement of boundary lengths, offsets and land areas, together with boundary demarcation and landholding mapping.
  • Survey outputs: Survey drawings, terrain models, maps and spatial datasets supplied in CAD and GIS formats suited to the project.

Where required, we also coordinate geotechnical investigations and engineering design services, allowing survey results to feed directly into the wider design process.

Project Focus

Kbal Hong Irrigation System

Topographic and geotechnical survey | Pursat

Aruna Technology was engaged by Pacific Rim Innovation and Management Exponents, Inc. (PRIMEX) to provide survey data for the design of a river regulator and associated works on the Pursat River. The assignment combined aerial mapping with detailed surveys of riverbanks, canal intakes and the regulator site.

  • Established four benchmarks and eight ground control points connected to the national survey network.
  • Completed UAV mapping over approximately 180 hectares, producing 3 cm orthophotos, a digital elevation model and 0.5 m contours.
  • Surveyed riverbank profiles and 62 additional cross-sections, and supplied drawings and digital outputs in GIS and CAD formats.

Aerial Mapping of the Okvau and Memot Mine Sites

Mine site survey | Mondulkiri and Tboung Khmum

For Renaissance Minerals (Cambodia) Ltd., Aruna Technology undertook aerial surveys of the Okvau and Memot sites, covering approximately 1,676 hectares in total. The work provided detailed imagery and terrain mapping for use in mine site planning and management.

  • Established three benchmarks and 16 ground control points tied to the national survey network.
  • Completed UAV surveys of approximately 1,166 hectares at Okvau and 510 hectares at Memot, at 3 cm image resolution.
  • Delivered orthophotos, digital elevation models, 0.5 m contours and survey reports, with outputs in GIS and CAD formats.

Ou Tapaong Tanai and Lum Hach Irrigation Surveys

Topographic and geotechnical survey | Pursat and Battambang

Aruna Technology undertook topographic and geotechnical surveys of the Ou Tapaong Tanai and Lum Hach irrigation subprojects for Climate Adaptive Irrigation and Sustainable Agriculture for Resilience (CAISAR). Conducted from December 2023 to February 2024, the assignment supported irrigation studies for the Ministry of Water Resources and Meteorology under AIIB Grant No. S0682A.

  • Conducted UAV aerial surveys of study areas covering approximately 14,500 hectares at Ou Tapaong Tanai and 25,000 hectares at Lum Hach.
  • Completed 30 geotechnical boreholes and soil investigations, with GNSS ground control and profile and cross-section surveys of rivers, streams, polders, drains and canals.
  • Produced orthophotos, elevation models, scheme maps, profiles and cross-section drawings, with reports and digital outputs in GIS and CAD formats.
