Earthquakes have always been a topic of discussion throughout history due to their sudden development and destructiveness. As long as the Earth's lithosphere, or upper crust, continues to move, they will continue to occur, and there is no technology that can prevent these disasters. Therefore, it is up to us humans to act based on data and take precautions. Thanks to geographic information systems (GIS), we can develop applications such as fault line movement and recent earth

The poles are some of the most remote, extreme, and least understood places on Earth. These icy shores are shaped by freezing temperatures, long periods of darkness and light, and vast snow and ice caps. Despite their harshness, they are not considered empty. These regions are home to unique ecosystems, extraordinary wildlife, and play a vital role in regulating the world's climate. In recent years, the poles have become increasingly popular with the global scientific commun

We always talk about forest fires afterward: how many hectares were burned, how many days did it last, how many people intervened? But the real question often lingers: Could we have foreseen this? In this article, we look not at the past, but at the possibilities. Thanks to two recent studies based on satellite data, we'll examine what nature tells us about where and when fires might break out. So, it's a little science, a little data, and a little effort to understand nature

Drought doesn't begin overnight. First, rainfall decreases, then humidity decreases, and plants lose their color. The key to understanding this silent progression is not just looking at the ground, but looking from above. Satellites have been tracking these changes for years. In this article, I'll explain how atmospheric irregularities are mapped, what data helps us predict soil drying, and why we should think of drought as a matter of "foreknowledge." What Does Drought Tell

As you read this, are you aware that you're leaving a mark on the world? Let me go even further: While you're running, walking, ordering food, looking for a date, or even waiting for your package, someone is watching you from above. And they're notifying you of what you're doing, wherever you are, and what you're doing. GNSS satellites orbit our planet, sending data every second. And we receive that data not just when we open a map application, but through numerous systems ru

An unmanned aerial vehicle (UAV) flies over a field or forest. Its camera takes hundreds of high-resolution photos, but it also captures colors in invisible wavelengths. So, what can such supervision reveal? For example, information such as chemical changes in plant leaves, soil moisture, or the material of a building's roof can only be revealed by processing photogrammetric (3D modeling) and hyperspectral (multispectral color analysis) data together. In this article, we'

Today, remote sensing is one of the most effective tools for observing and understanding the world. Often without fieldwork, imagery obtained from above or from orbit allows us to quickly collect data across vast areas. This data can be processed and used in a wide range of fields, from engineering to environmental management. In this article, we will explore the fundamental definition of remote sensing, image processing, and classification methods. We will also examine its a

Carl Gauss long ago demonstrated the impossibility of transferring the world onto flat paper . Just as it's impossible to peel an orange and make it perfectly flat, creating a map of the Earth's surface inevitably distorts some of it. Projections are mathematical methods that show us how to manage these distortions. When deciding which feature to preserve, we ask ourselves: shape, area, or distance. Ultimately, every projection perfectly preserves a limited feature, while o

The Earth's crust isn't just a flat plate; it's a gigantic labyrinth filled with fractures, potholes, and high peaks. So, how can we bring this complex labyrinth to our computer screen? In the world of cartography and GIS (Geographic Information Systems), surface modeling is the answer to this question. Every point on Earth has an elevation value, and the "digital surface" formed by combining these values can be represented using various methods. This article will examine th

Once upon a time, maps were shaped by a sheet of paper on a brown table, a pencil at the edge, and a thoughtful engineer at the helm. Today, this scene has become digital. Digital maps displayed on computer screens are no longer just directions; they have become intelligent systems that encode the future of cities, disaster risks, and infrastructure. So how are these digital maps produced? The answer lies in the seamless integration of multiple technologies: CAD and GIS softw

Today, more than 58 million parcels in Turkey can be searched digitally in seconds. How is this possible ? The answer lies in the years-old databases and modern technologies of the General Directorate of Land Registry and Cadastre (TKGM) in Turkey. Since 1924, cadastral engineers have completed the measurement of approximately 58.5 million parcels, creating the country's two-dimensional cadastre. Managing this vast real estate stock today requires not only traditional mapp

The Earth's surface is shaped by tectonic movements and various other external factors. This results in mountains, rivers, valleys, and other rugged terrain. In areas like construction sites or logistics, looking at a 2D map is inefficient because factors like terrain slope and elevation are inaccessible. Therefore, topographic maps are used. So, what is a topographic map, how is it made, and in what areas is it used? The answers to all these questions are here. Contents What

You're holding a photograph taken from the sky; can this image serve as a measured map ? This might seem like a negative idea to many. However, orthophoto technology achieves precisely this impossible. There's a photograph, and every point in this scene has been meticulously mapped to its real-world coordinates. Orthophotos represent a measurable reality . These images, at the heart of modern cartography, provide critical data layers in many areas, from land and sea to airp

Satellites silently orbiting in space, like vast "observation towers," constantly take photographs from a distance. Farmlands, forests, cities, and disaster areas around the world are becoming visible thanks to these devices, the eyes of space, even if they don't always utilize light. So, is this bold Sentinel or Landsat ? Or why are other satellite systems like SPOT , Pleiades , Göktürk , and WorldView preferred? In the rest of this article, we'll answer these question

When we open a map on our smartphone, our location is actually determined by the synchronized operation of dozens of satellites in the sky. So, what's behind the "GPS" we see on that screen? GPS (Global Positioning System) isn't just a standalone system these days. We're in the age of GNSS (Global Navigation Satellite Systems). GNSS includes multiple satellite constellations, including America's GPS, Russia's GLONASS, Europe's Galileo, and China's BeiDou, in addition to Ame

Climate change is infiltrating our lives rapidly and effectively. Droughts, floods, wildfires... Amidst this chaos, we have a powerful compass: Geographic Information Systems (GIS) and remote sensing technologies. With these technologies, we can monitor climate risks virtually live—pixel by pixel. Modern maps don't just show rivers and mountains; they also reveal water scarcity, agricultural productivity, and climate stress. Thanks to satellite imagery and sensor data, maps c

Today, maps are more than just a guide. We can view weather conditions, traffic flow, disaster risks, and even social media activity in real-time. Thanks to modern online mapping services, this dynamic information gains meaning through constantly updated map layers. So, how do these systems work, and why should we choose one when developing a project? In this article, I'll cover the basic principles of online mapping services, the installation and integration steps for these

To what extent do the maps we have today represent reality on the ground? This question is not merely a technical consideration; it also opens the door to a situation with economic, social, and legal implications. The up-to-dateness of cadastral maps directly impacts numerous processes, from urban planning and agricultural production to infrastructure investments and property rights. However, a significant portion of the maps we have are based on data produced with the limite
