Elevation USGS SRTM

USGS EROS Elevation Map

This service provides an elevation map for your specified region of interest at 1 arc second (~30m) resolution.

The imagery is output as a GeoTIFF file representing elevation. A preview image is also provided. The GeoTIFF file has a resolution of 30m. Further information about the Shuttle Radar Topography Mission (SRTM) data can be accessed via here.

Detecting Greenhouse Gas Emissions

Monitoring the occurrence and volume of methane leaks

Reducing methane emissions is imperative in the fight against climate change. Methane is a potent greenhouse gas with around 80 times more warming capacity than carbon dioxide, meaning that a large reduction in emissions would result in a significant step towards climate goals and a liveable future. D-CAT has developed algorithms using existing remote sensing sources to detect methane emissions, map plumes and estimate emission volumes across the globe.

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 Wildfires

Western USA, Oregon State

There is an increasing need for affordable, effective monitoring of the environment, with the recent wildfires in the western US states being only the latest example. Each year the number of wildfire outbreaks across the globe increases, as does the need for faster detection of fires and the ability to reliably monitoring them through degraded conditions. With forests covering millions of acres of land worldwide, satellite-based imaging services from D-CAT can play a key role in monitoring fire risk for all stakeholders, including fire-fighters.

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.
