What is a Geodetic Survey?

A geodetic survey is a high-precision method of measuring large areas of the Earth's surface using a mathematical model of the Earth’s shape. It takes into account the Earth's curvature and is used for mapping, navigation, satellite positioning, and large infrastructure projects.

This survey forms the foundation for all other types of surveys and is essential for defining global and national coordinate systems. It is typically used in projects that require extreme accuracy over long distances, such as highways, railways, and large government mapping schemes.

Why Choose Geodetic Surveys?

• 1. Global Accuracy: Uses reference systems like WGS 84 or UTM for precise mapping.
• 2. Supports Engineering Projects: Used in building roads, railways, airports, and large-scale infrastructure.
• 3. Coordinates for Satellite Systems: Essential for GPS, remote sensing, and telecom alignment.
• 4. Curvature Correction: Accurately accounts for Earth’s curved surface, unlike local surveys.
• 5. Used in National Mapping: Helps governments in creating base maps for planning and disaster management.

Who Needs a Geodetic Survey?

• 1. Government Mapping Agencies: For creating and updating national geospatial data.
• 2. Infrastructure Developers: In railways, bridges, highways, and cross-country pipelines.
• 3. Space & Satellite Applications: For ground control stations and orbit data correction.
• 4. Telecom Companies: For tower alignment and accurate positioning across large areas.
• 5. Hydrographic & Aviation Projects: For elevation and ground position referencing.

Frequently Asked Questions (FAQs)

• Q1. What is the difference between geodetic and topographic survey?
  Topographic surveys focus on local terrain features, while geodetic surveys consider the Earth’s curvature and global reference systems.
• Q2. Is geodetic surveying necessary for every project?
  No. It is mostly required for large-scale or high-accuracy engineering and infrastructure projects.
• Q3. What instruments are used in geodetic surveying?
  GNSS receivers, total stations, digital levels, and specialized geodetic software.
• Q4. Do you provide geodetic control for satellite mapping?
  Yes. Bhoojal Survey provides base control networks for satellite and drone-based projects.
• Q5. Can I use your geodetic data for GPS alignment?
  Yes. Our geodetic points are suitable for GPS correction and telecom tower alignment.
