Question 1

What is the cost of a Bathymetric Survey in India for 2026?

Accepted Answer

The cost depends on the area's size, depth, and required resolution. In 2026, integration with USV technology has made surveys more cost-effective for reservoirs and canals. Contact Droid Survair for a customized quote.

Question 2

How does Droid Survair calculate Reservoir Siltation and Storage Capacity?

Accepted Answer

We use high-frequency Echo Sounders to map the bed level. By comparing this with historical surveys in a GIS environment, we calculate the volume of sediment accumulation and remaining capacity with 99% accuracy.

Question 3

Why is USV (Unmanned Surface Vehicle) better for shallow water bathymetry?

Accepted Answer

USVs allow for safe, high-resolution data collection in water as shallow as 0.5 meters, where traditional human-operated boats often struggle or cannot navigate.

Question 4

What is the difference between Bathymetric and Hydrographic Surveys?

Accepted Answer

Bathymetry focuses strictly on underwater topography and depth for volume calculations. Hydrography is broader, including tides, currents, and navigational hazards.

Question 5

Can Bathymetry be integrated with Drone LiDAR data?
