This section called FAQ (frequently asked questions) has been drafted to help explain the most frequently asked questions about our company, the technology we use and what we offer in a clear and structured way. As questions keep reaching us, we strive to answer most of them and add the most frequently asked ones below.
For any questions that have not been listed, please contact us per e-mail or just give us a call.
1. What exactly does EOS offer?
The Earth Observation Services GmbH offers solutions with regard to environmental issues that need or greatly benefit from data, which in turn is produced by earth observing optical (including infrared), and radar satellite data. This information is extracted from data which in turn is produced by earth observing optical (including infrared) and radar satellites and can be used for a host of different applications.
Due to the versatile possibilities that satellite images offer in terms of extracting the information contained within these satellite measurements, EOS has yet to find a one-size-fits-all solution. Therefore, EOS has specialized in offering customized solutions for different kinds of challenges you might have. We are at our best, when your challenge involves forest areas, agricultural land, urban areas and/or large areas of water.
Please find examples of the Information that can be extracted from the satellite measurement data in our Showcase menu. For a complete overview of the services we can provide you with, please visit our Services page.
2. What are satellites?
The word satellite is of Latin origin and is thought to mean bodyguard. In the context of space exploration and technology a (n) (artificial) satellite is an object which has been deployed in space by human doing.
Using this definition, pieces of rockets and all other forms of debris from the countless space missions can therefore also be called satellites. The satellites we refer to on this website are operational measurement or communication platforms that circle with or around the Earth in a certain orbit.
3. What kind of satellites are there?
There are different kinds of satellites, which can be categorized into approximately five different groups, the first of which are communication satellites (e.g. communication media like TV, radio and telephone) followed by navigational satellites (e.g. GPS), weather satellites (e.g. to make weather forecasts), military satellites (e.g. spy missions, communications and other objectives unknown to the public) and scientific satellites (e.g. space exploration and earth observation) which contribute to the knowledge expansion and everyday life of ourspecies.
In total there are about 1.200 active satellite circling the Earth. Besides them, there are thousands of particles of different sizes called space debris, which are the remains of rockets and abandoned satellites (if they have not been de-orbited). These objects may be a threat for active satellites and have to be constantly tracked.
4. What does GIS stand for and what does it encompass?
GIS stands for Geographic Information System. These computer data systems are capable of and designed for capturing, storing, analyzing, and displaying geographically referenced information. Geographically referenced information describes information that has been complemented with the geographic locations of that information.
A GIS consists of several components such as hardware, software, data and people. The hardware involved consists of a computer or server that is able to load large quantities of data (raw data) and is able to facilitate graphic manipulation of this data. One of the most important components of a GIS is the software, which provides the opportunity to interpret the data and turn it into new information using different kinds of algorithms, software tools and additional information such as e.g. roadmaps, elevation models or weather prediction models to get new insights with regard to our environment. Another key element in a GI-System is the remote sensing data. Last but not least, it’s the people that work with GI-Systems that have to possess the necessary knowledge to interpret and visualize these new insights, so as to make sure they are relevant and understood by those who depend on this new information for their decision making process.
