A base line survey involves establishing a straight reference line (baseline) across a survey area. This line is carefully measured and used as the primary reference for all other measurements and calculations.

A hydrographic survey is the process of measuring and mapping physical features of water bodies such as oceans, rivers, lakes, and coastal areas.

A topographic survey is one of the most fundamental types of land surveying used in construction, engineering, and planning. It provides a detailed representation of the surface, including natural and man-made features, helping professionals make accurate and informed decisions.

A construction survey is a critical part of any building or infrastructure project. It ensures that structures are built in the correct location, at the right elevation, and according to the approved design. Without accurate surveying, even small errors can lead to costly mistakes and delays.
