One of the most important discoveries in the field of earth observation is the discovery of spectral indices. At dawn of the development of this branch, it turned out that in many cases the analysis of spectral reflectance in certain spectral zones was not enough. In some cases, the ratios or differences of reflection of […]
One of the main tasks of Earth observation is the monitoring of objects and phenomena on its surface. The regularity of the satellite remote sensing allows for constant monitoring and quick detection and evaluation of changes in natural and transformed landscapes. This information is very useful and is applied in land use management, forest management, […]
Ukraine is rich in natural resources. However, such richness often bears to the nation not the prosperity but new problems – social, political, and environmental. One of the brightest examples is so-called “amber fever” that flushed out in Ukraine recently. Rising prices for amber in the world market after 2010 accompanied with a long-term deepening […]
It seems that our previous posts have shown all the complicity and importance of soil map creation process. Remote sensing (RS) is a powerful and promising tool for improving this process. This term can be interpreted very freely, it covers various means of obtaining information, depending on the electromagnetic wave range used, equipment applied and […]
We’ve prepared a list of upcoming free online courses in GIS, remote sensing and other useful things. Below you can also find the courses that can be taken anytime. Feel free to add more links in the comments! Data Analysis and Interpretation Specialization Data Management and Visualization Data Analysis Tools Machine Learning for Data […]
The European Space Agency is working on a family of satellite missions called the Sentinels. These missions are owned and managed by the EU as part of the Copernicus programme, that is said to be one of the most ambitious Earth observation programmes to date. It aims to give timely, accurate and accessible information for […]
Modern software for satellite image processing offers its users a wide range of supervised classification algorithms (more detail can be found here). It yields powerful capabilities for automation of the image interpretation process. In return for that, a user should make training areas of high quality. It is this quality what defines the accuracy of the […]
Bodies emit radiation. The warmer the body the more the emittance. When we look at the Sun, or even feel it on our skin without actually seeing it, we definitely know that it emits radiation. Especially when we forget about sunscreen. From Wien’s displacement law we can learn that the peak radiation of a black […]
In this post we will try to search for the Martian on the surface of the planet. In a way it is strange how humans are fascinated by space. I have a biologist friend who hates space exploration and she is right in her own way. Having this wonderful planet full of mysteries, undiscovered, extinct, […]
Intro to Remote Sensing. Part 1 This is the first post of a series talking about core concepts of remote sensing. Here we will talk about electromagnetic radiation. On my bumpy road towards an MSc diploma, in the very beginning – in fact, somewhere halfway the “GOEG6062: Core skills in remote sensing” course – it […]
