Techniques As spatial interrelationships are key to this synoptic science, maps are a key tool. Remote sensing Remote sensing is the science of obtaining information about Earth features from measurements made at a distance. Ethnography Geographic qualitative methods, or ethnographical research techniques, are used by human geographers.

The descriptions of five of them have survived. Not until the time of the Greek philosopher-geographers did speculations and conclusions as to the nature of the Earth begin to take form. Few of the maps and related works of the ancient world have come down to us in their original forms. In fact, by jet from Moscow, it takes about eight hours to reach Vladivostok on the Pacific Ocean coast. Cartography Cartography studies the representation of the Earth's surface with abstract symbols map making.

He also discussed human geography and the planetary habitability of the Earth. The main aim is to understand, or define the uniqueness, or character of a particular region that consists of natural as well as human elements.

The Romans were less interested

The shortage of arable land in their own region led to maritime exploration and the development of commerce and colonies. The eighth volume was a most important contribution, containing instructions for preparing maps of the world and discussions on mathematical geography and other fundamental principles of cartography.

The accompanying text mentions seven outer regions beyond the encircling ocean. Geomatics has led to a revitalization of some geography departments, especially in Northern America where the subject had a declining status during the s. Cartography has grown from a collection of drafting techniques into an actual science. The foundations of geography can be traced to the ancient cultures, such as the ancient, medieval, and early modern Chinese. Both were vitally concerned with the fertile areas of their river valleys and therefore doubtless made surveys and plats soon after settled communities were established.

Remotely sensed data may be analysed either independently of, or in conjunction with other digital data layers e. It is quite probable that these two civilizations developed their mapping skills more or less concurrently and in similar directions.

The Russian landmass west of the Ural Mountains shown above in a lighter shade of grey is referred to as European Russia by most educational atlases and geography experts. They must learn geodesy and fairly advanced mathematics to understand how the shape of the Earth affects the distortion of map symbols projected onto a flat surface for viewing. The idea gradually developed into a consensus over many years. There is some debate about who was the first person to assert that the Earth is spherical in shape, with the credit going either to Parmenides or Pythagoras. He often combined astronomical readings and mathematical equations, in order to develop methods of pin-pointing locations by recording degrees of latitude and longitude.

The problem facing both explorers and geographers was finding the latitude and longitude of a geographic location. The tragic turn of world events during the first few centuries of the Christian Era wrought havoc to the accumulated knowledge and progress of mankind. Library of Congress, Washington, D. Environmental geography has emerged as a bridge between the human and the physical geography, as a result of the increasing specialisation of the two sub-fields.

The Romans were less interested in mathematical geography and tended toward more practical needs for military campaigns and provincial administration. References to many other Roman maps have been found, but very few actual specimens survived the Dark Ages.

One of the first estimates of the radius of the Earth was made by Eratosthenes. Geomatics emerged from the quantitative revolution in geography in the mids. Thales is also credited with the prediction of eclipses.
