Monitoring of water resources using satellite imagery

Monitoring of water resources using satellite imagery

Water, one of the most important natural resources on the earth, plays a significant role in our day-to-day life. Numerous resources of consumable water include rainfall, groundwater, and various surface water bodies such as ponds, rivers, lakes, etc.

The management of water resources can be challenging all over the world. This might be a result of extremes in water cycles such as droughts and floods that destabilize vulnerable populations.

These places are often found to be very hydrologically data-prone areas. To make up for a shortage of water data, a consequence of limited in situ monitoring networks, many scientists and water managers in low-income countries rely on remotely sensed data acquired from satellites.

With many decades of technological advancement. Satellite-based sensors orbiting Earth can now measure precipitation, evaporation, surface water levels, soil moisture, snow depth, groundwater, and more.

The satellite and sensor boom of the past few decades has resulted in unprecedented data streams, with more missions slated to launch in the coming years.

The challenge faced in water quality monitoring occurs when the remote sensor picks a suitable method to find the relationship between the satellite data and collected water quality samples. Different methods have benefits and limitations for scale and model complexity.

The fitting of a standard linear regression between remote sensing data and collected water quality samples is the most common method used.

That comes with the limitation that it typically cannot be generalized across large space and time scales.

To bridge this gap, other methods model the water body properties that depend only on the medium in coordination with those that depend on the ambient light field.

These methods require large amounts of collected water quality samples. Thus, they are still a challenge.

 

Aside from water quality monitoring.

It is vital to keep in mind, that Geoinfotech seeks to provide our clients with a complete solution. Making water quality mapping a crucial part of it all. By connecting with other experts and also with industrial partners, we can provide our clients with the solutions they need.

We also keep track of the latest technological advancements and integrate them into our research and products to improve our expertise and expand our offer. From beach morphology over coastal infrastructure to ship detection.

we analyze these trends and patterns to support policymakers in identifying appropriate measures at different locations in their area of interest.

In addition, Geoinfotech sees satellite-derived datasets as essential in maximizing the quality of output of simulation models to support decision-makers, particularly in data-scarce areas. Contact us, to discover the appropriate imagery for your project.
