How to select your drone and perform image orthorectification
1. The Combustion chamber, where the propellant burns, producing hot gasses! 2. The Throat is designed to constrict the flow of hot gasses, which will build up the combustion chamber, controlling the chamber pressure and mass flow rate! Important Notice - The hot gasses reach the speed of sound in the throat! 3. The Nozzle is designed to efficiently direct the flow of gasses in the desired direction!
Let's start asking Remote Sensing related questions and get simple focused answers.
There are numerous methods and techniques to extract information from a hyperspectral image (HSI). By taking into account the complexity of the data as well as, the different objectives of each application, there is not a single information extraction technique that outperforms all others in every practical situation
Nowadays, along with the development of information technology, GIS is also applied in socio-economic development more urgently than before. The development of GIS is considered as a new step in spatial data management. So what is GIS? What are GIS Applications in everyday life? Let’s find out in the following article
Climate is changing. Constantly. Our most fragile ecosystems, Glaciers are the ones that are first affected by global warming. How to use multispectral images to map glaciers of the world?
The Sustainable Development Goals are the blueprint to achieve a better and more sustainable future for all. They address the global challenges we face, including those related to poverty, inequality, climate, environmental degradation, prosperity, and peace and justice. The Goals interconnect and in order to leave no one behind, it is important that we achieve each Goal and target by 2030
So you are interesting in downloading satellite images? Let's start from the top by defining a satellite image. Satellite images or in a more scientific terminology, satellite remote sensing images, are data in the form of images that are collected using satellites in orbit around the Earth.
What is a spectral index? A spectral index is a mathematical equation that is applied on the various spectral bands of an image per pixel.
SAVI or Soil Adjusted Vegetation Index is a spectral index introduced by Huete in 1988. SAVI attempts to be a hybrid between the ratio-based indices and the perpendicular indices. The reasoning behind this index acknowledges that the isovegetation lines are not parallel, and that they do not all converge at a single point. SAVI can be calculated based on the following equation
