Climate Weather USGS Landsat 8/9

Land Surface Temperature from Landsat

This service provides high resolution land surface temperature data from Landsat for your specified region of interest.

The panchromatic band of Landsat 8 & 9 is used to provide a sharpened (100m to 15m, up-sampled to 10m) version of Landsat's TIR 1 band. An optional non-negative alpha value can be supplied to adjust the sharpening with 0 representing no sharpening and any positive value resulting in some sharpening. The default value of 1.0 provides a generally acceptable trade-off between resolution and accuracy. Temperatures that vary by more than 2 degrees are capped.

Predicting Crop Yield

Forecasting wheat production months before harvest

A strong and stable agriculture sector is important at a national level as a source of food, and beneficial as a source of economic gain through exports. Early prediction of harvest yields at national and regional scales is therefore important as an influencer of commodity trading pricies, a means of ensuring adequate food supplies, managing logistics, and as a component of balance of trade. At a smaller scale, accurate estimates of likely yields allow farmers to better manage budgets, plan seed retention versus sales, assist with insurance cover judgements, and crop management decisions through the latter part of the growing season. Crop yield prediction is possible using remote sensing from satellite imagery, and accurate predictions of wheat yield are shown below to be possible months before harvest.

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.

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.
