Agriculture Frost Damage Detection

Frost Damage Detection

This service detects signs of frost-damage to crops after a frost event, including tree crops and vines, for a region of interest, and delivers a severity map along with associated statistics.

This service has been proven to detect the effects of frost damage in crops (cereals, legumes, tree crops and vines) after a frost event. Given a region of interest and the frost incident date, the algorithm is run using Sentinel-2 to return a relative frost damage map across that area. The output is provided as a GeoTIFF classifying frost damage (1) and no frost damage (0). A GeoTIFF is also provided which details the minimum temperature during the period covering +/-5 days around the incident date. A preview image is also provided along with an outline of the frost areas as a series of polygons (where the minimum size of the polygons can be optionally modified using the options). A CSV file is also output containing data for the whole area and individual fields/paddocks, which includes frost area and percentage.

After COP 26

Measuring Progress

The 20,000 activists, diplomats, politicians, media, and businesspeople attending COP26 in Glasgow have the needs and focus of an expectant world on them. COP 26 is, after all, the forum to force climate change. When the summit ends, new goals will have been set.

Soil Monitoring for Sustainable Land Use

Satellite-Derived Top-Soil Mapping: Uses & Benefits

Understanding soil is vital for good agricultural outcomes and sustainable land use management, but methods for mapping and monitoring typically require manual intervention. Satellite-derived top-soil indices do not, and are therefore offer an attractive alternative – or addition – to other data gathering methods.

Monitoring Land Surface Temperature

Smart processing for higher resolution images

The challenge to monitor changing temperatures in urban and rural areas has never been more real or important. Most commonly, temperature readings are taken by measuring the temperature of the air. However, this has a major drawback in that it cannot account for variation of temperature on different surfaces and materials. To do so, Land Surface Temperature (LST) is required. LST readings are generally obtained through remote sensing observations from satellites, which offer the benefit of monitoring cities, regions and nations at scale and at regular intervals. What differentiates D-CAT’s LST product is the unparalleled spatial resolution of 15m enabling more precise spatial insights.

Monitoring Oceans and Coasts with Remote Observations

Detecting Oil Spills

There is an increasing need for using insightful remote sensing to monitor the environment. Rising levels of pollution and temperature in oceans have caused concern for the impact on aquatic life and coastal regions. With oceans covering over 70% of the Earth's surface, solutions are needed that allow large regions to be monitored quickly and effectively, providing more than imagery alone. D-CAT offer services which help clients to manage and protect fragile ecosystems.

Platforms & APIs

Robust cloud platforms and API solutions

Being able to extract insight from data is not enough to be useable by customers to solve their problems. Needed alongside clever algorithms is the ability to develop robust, secure and useable solutions which, for example, integrate with customer systems, or provide stand-alone systems which can be used by end users.
