Surveying Division:

Land surveying operations: linear and angular measurements, computational processing of observations, and presentation of results in hardcopy or digital format using total stations for detail surveys (cadastre, topography, plans, etc.), leveling instruments for elevation transfer, and triple-frequency GPS for precise positioning of surveying stations and coordinate transfer.

  • Setting out of surveying stations
  • Leveling operations
  • Setting out points along the route
  • Surveying of all features appropriate to the scale, including point, linear, and surface features such as power poles, towers, trees, wells, canals, watercourses, roads, rivers, garden boundaries, cuttings, embankments, etc.
  • Processing of surveyed data and preparation of output files
  • Cartographic operations and map preparation based on all surveyed features, including point, linear, and surface features, as well as addition of descriptive data, symbols, and surface patterns to maps in accordance with standard layering; preparation of longitudinal and cross-sectional profiles, etc.

Aerial photogrammetry operations using drones: production of 3D models, orthophotos, colored point clouds, and preparation of topographic maps, urban parcel maps, cadastral maps, and other thematic maps within an optimal timeframe and cost, with higher detail compared to ground surveying methods.

  • Production of digital elevation models in aerial surveying: digital elevation models are among the most important outputs of drone-based surveying. By extracting DTM, DSM, and DEM, highly accurate digital models can be produced.
  • Preparation of topographic maps: integration of ground and aerial surveys, including acquisition of orthogonal images in a uniform manner, precise detail surveying at breakpoints, cuttings, and other topographic features, and preparation of standard topographic maps at scales of 1:2000, 1:1000, and 1:500.
