Terramonitor satellite images in media

Terramonitor satellite images in media

Terramonitor works in cooperation with various companies and organizations that want to use the information obtained from satellites in their own processes. One industry we cooperate with is media. Satellite images are an important source of information for news and media services. The largest newspaper in the Nordic countries, Helsingin

Satellite images in business

Satellite images in business

Like businesses, satellite technology develops at breakneck speed, satellite images have proven to be valuable tools to support companies' business operations. Accurate and widely available images captured by satellites from the earth are changing the way we look at the world, also in business life. One of the most

How good are the satellite images compared to aerial images?

How good are the satellite images compared to aerial images?

Satellite images have become an everyday part of modern life, allowing us to view our life from a bird eye perspective. But what can be actually seen from these images? Optical satellite images are captured by orbiting satellites that use various bands to detect and radiation emitted or reflected by

Introduction to radiometric calibration

Introduction to radiometric calibration

Absolute radiometric calibration is a technique used to ensure the accuracy of the radiance values measured by satellite sensors. Radiance is a measure of the amount of light that is reflected from the earth's surface, and is an important factor in the interpretation and analysis of satellite imagery.

Satellite images, to see or not to see

Satellite images, to see or not to see

Usually talking about earth observation we talk about optical satellite images similar to our family photos. On top of these optical images, satellite data can be produced with other bands such as synthetic aperture radar, also known as SAR or by using several different bands for example to detect heat,

The Fastest Way to Extract Values from Geospatial Data

The Fastest Way to Extract Values from Geospatial Data

A considerable part of what we do at Terramonitor can be summed up by the extract, transform, load (ETL) paradigm. This happens both in internal processes and in those that are externally triggered. And sometimes those processes are too slow.

Earth observation

If algorithms could talk, part 1

Currently thousands of earth observation satellites are sending data to the surface around the clock. My goal is to make the most out of that data. This story is about one of my recent projects. In the following example case, the goal was to produce a cloudless view of a
