So, to summarize before we continue, we now have a key answer, studying the subject is important because without geographical knowledge we would know very little about our surroundings and we wouldn’t be able to identify all the problems that relate to them. So, by definition, we wouldn’t be in any informed position to work out how to solve any of them.Ok, now for some practicalities. What do geographers actually do？ Well we collect data to begin with, you’ll be doing a lot of that in your first field trip. How do we do this? There are several means, we might, for example, conduct a census, count the population in a given area perhaps. We also need images of the earth’s surface which we can produce by means of putergeneration technology or with the help of satellite relays. We’ve e a very long way from the early exploration of the world by sailing ships when geographers only had pens and paper at their disposal. After we‘ve gathered our information, we must analyze it. We need to look for patterns, most monly those of causes and consequences. This kind of information helps to predict and resolve problems that could affect the world we live in But we don’t keep all this information confidential, we then need to publish our findings so that other people can access it and be informed by it. And one way in which this information can be published is in the form of maps. You’ll all have used one at some stage of your life already. Let’s consider the benefits of maps from a geographer’s perspective. Maps can be folded and put in a pocket and can provide a great store of reference when they’re collected into an atlas. They can depict the physical features of the entire planet if necessary, or just a small part of it in much greater detail. But there is a drawback, you can’t exactly replicate something that is 3dimensional, like our planet, on a flat piece of paper, because paper has only 2 dimensions. And that means there’ll always be a certain degree of distortion on the map. It can’t be avoided. We can also use aerial photographs. Pictures taken by cameras at high altitude above the earth, these are great for showing all kinds of geographical features that are not easy to see from the ground. You can easily illustrate areas of diseased trees, or how much traffic is on the roads at a given time, or information about deep sea beds for example. Then there are landsats. These are satellites that circle the earth and transmit visual information to puters at receiving stations. They circle the earth several times a day and can provide a mass of information. You’ll all be familiar with the information they give us about the weather for example. So what we are going to do now is to look at a short presentation in which you’ll see all…..
