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. To perform

Supporting ecosystems using satellite images

Forests are essential in maintaining healthy ecosystem interaction and biodiversity on Earth. They are in a key role in the fight against climate change since they can restore increasing carbon stocks. Hence, several national and international initiatives (including the UNFCCC Paris Agreement and the EU LULUCF Regulation) require regular reporting

Climate change mitigation using satellites

Climate change mitigation using satellites

Forest biomass and carbon monitoring play a key role in climate change mitigation. Operational large area monitoring approaches are needed to enable forestry stakeholders to meet the increasing monitoring and reporting requirements. Terramonitor provided calibrated satellite images for a scientific research project carried out with VTT Technical Research Centre of

Terramonitor Web Store

Press release, May 28 2020 Terramonitor launches a Web Store that provides easy access to analysis-ready satellite images and up-to-date satellite maps. By processing thousands of satellite images per day with AI and cloud computing, Terramonitor provides revolutionary tools for monitoring and analyzing the globe from space. Terramonitor, a leader

VESA Index technology

VESA Index technology

Terramonitor has developed a machine learning based mapping service, which locates harmful shrubs in boreal forests. The service provides valuable information for forest professionals about growth states of forests. The maps of Terramonitor’s VESA index help forest professionals for fast, easy and financially prudent shrub maintenance. Region-specific maps point

Machine Learning

Raster Matrix Algebra part 1

In geoinformatics, a raster image is a dot matrix data structure that represents a (generally) rectangular grid of pixels. Most satellite images are stored into a raster file format at some part of the processing chain. GeoTiff and JPG2000 are examples of raster file formats that can have a specific

Satellite mosaic validation by Terramonitor Labs

Let's say you have a Sentinel-2 satellite image mosaic over a large area, for example Russia. The image is supposed to represent the surface reflectance of the area. How do you know if the pixel values are actually correct and that the atmospheric correction and the radiometric normalization of the

Errors related to the automatized satellite-based change detection of boreal forests in Finland

Terramonitor took part in a Finnish government head project related to detecting changes in boreal forests during 2016-2019. Time series change detection.The project was executed by Teknologian tutkimuskeskus VTT Oy, Natural Resources Institute Finland, Finnish Forest Centre, Finnish Environment Institute and Terramonitor. Examples of clear-cut and thinning detection.Some

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

NDVI(BOA) vs. NDVI(TOA)

Earth observation

NDVI(BOA) vs. NDVI(TOA)

The normalized vegetation index (NDVI) is a remote sensing measure that describes the difference between visible and near-infrared reflectance and can be used to estimate the density of green vegetation on land. NDVI is defined by the formula where red and NIR stand for the spectral reflectance measurements acquired in
