Primary Division of Surverying

 The primary divisions of surveying are:

1. Geodetic Surveying: deals with large-scale, precise measurements of the Earth's surface, including its shape, size, and gravity field.

2. Plane Surveying: deals with smaller-scale, two-dimensional measurements of land, including the location of boundaries, topography, and features.

3. Engineering Surveying: provides critical information for the planning, design, and construction of infrastructure projects, such as buildings, bridges, roads, and utilities.

4. Mining Surveying: deals with the measurement and mapping of mines and mining operations, including shafts, tunnels, and ore deposits.

5. Hydrographic Surveying: deals with the measurement and mapping of bodies of water, including rivers, lakes, and oceans.

6. Photogrammetric Surveying: deals with the measurement and mapping of the Earth's surface using aerial and satellite imagery.

7. Geospatial Surveying: combines the use of technology and surveying techniques to create and manage geospatial data, such as maps and digital models.
