Topographic & GNSS/DGPS Surveying

Topographic & GNSS/DGPS Surveying Services in Nepal

We specialize in topographic and GNSS/DGPS surveying services in Nepal. Our comprehensive surveying services are essential for various projects, including land development, construction, and infrastructure planning. With a focus on precision and efficiency, we utilize advanced technology to deliver reliable data for our clients.

What is Topographic Surveying?

Topographic surveying involves mapping the natural and artificial features of the land, including:

  • Elevation changes
  • Contour lines
  • Vegetation
  • Buildings and structures

By providing detailed topographic maps, we help clients visualize the land’s characteristics, aiding in effective planning and design.

GNSS/DGPS Surveying Methodologies

We employ state-of-the-art GNSS (Global Navigation Satellite System) and DGPS (Differential Global Positioning System) technology to ensure high accuracy in our surveys. Our methodologies include:

Static GNSS Surveys

Static GNSS surveys involve collecting data from a fixed location over an extended period. By measuring the same point multiple times, we can achieve higher accuracy. This method is particularly useful for establishing control points and reference stations for larger surveying projects.

Real-Time Kinematic (RTK) Surveys

RTK surveying uses satellite signals to provide real-time corrections, achieving centimeter-level accuracy. This method is ideal for precise applications such as:

  • Construction staking
  • Boundary surveys
  • Topographic mapping

By employing RTK, we can significantly reduce time spent on-site, delivering rapid and reliable results.

Post-Processing Kinematic (PPK) Surveys

PPK surveying is similar to RTK but involves collecting data from the rover and base station separately. After data collection, the information is processed to improve accuracy. This method is beneficial in areas with poor satellite visibility, where real-time corrections may not be possible.

Advanced Surveying Equipment

Our surveying toolbox includes advanced equipment to enhance accuracy and efficiency:

Total Stations

Total stations are versatile surveying instruments that combine the functions of an electronic theodolite and an electronic distance measurement device. They allow us to measure both angles and distances, enabling precise positioning for various applications.

Auto Levels

Auto levels are used to establish horizontal planes. They are essential for tasks such as:

  • Site grading
  • Drainage projects
  • Foundation layout

Traversing

Traversing is a method used to establish control networks by measuring angles and distances between multiple points. This technique is particularly effective in expansive or complex terrains.

Contour Map Preparation

We specialize in contour map preparation, which is crucial for understanding land topography. Our process involves:

  • Collecting elevation data from survey points
  • Creating contour lines to represent elevation changes
  • Generating 3D models for visual representation

Contour maps provide valuable insights for land development, helping clients make informed decisions regarding design and construction.

Data Visualization and Reporting

Once the surveying is complete, we provide comprehensive reports and data visualization. Our services include:

    • Detailed survey reports outlining findings and recommendations
    • Graphs and charts to illustrate data trends
    • GIS mapping for spatial analysis and planning

Land Surveying in Challenging Terrain

Conducting land surveys in tough terrain poses unique challenges, including:

  • Steep slopes and rugged landscapes
  • Dense vegetation that obstructs visibility
  • Remote locations that may require special access equipment

Our team is experienced in overcoming these challenges, ensuring accurate data collection even in the most difficult environments.

Applications of Topographic Surveys

Our topographic surveying services are utilized in various applications, including:

  • Land development projects
  • Construction planning
  • Irrigation projects
  • Disaster assessment and recovery
  • Landslide monitoring
  • Utility mapping
  • Personal property surveys
