You are watching: What is a three dimensional representation of the earth
1 MR. WOMACK geography Maps and also Globes
2 A globe is a three-dimensional depiction of the earth. It gives a method to see the earth as it travels with space. Maps room two-dimensional graphic representations of selected components of the earth surface.
3 What is this map mirroring us?
4 and this one?
5 advantages and flaw Globes display the earth true shape, but they are not very practical due to the fact that they are not quickly portable. Maps are easily portable, and also can be drawn to any kind of scale needed. However, distortion can occur because the earth’s surface has been distorted to create the map.
6 Who renders maps? Cartographers- or mapmakers, make maps and must update them come reflect political and also environmental transforms to the globe. They also use something dubbed map estimate to alleviate distortion through presenting a round earth on level paper.
7 types of Maps Topographic- represents natural and also man- made attributes on the earth. Political-Show boundaries set up through governments. These limits are not constantly physical. Thematic-they emphasize details kinds of details such together climate or population. Navigation-Used by sailors, pilots, and geo- cachers.
8 thematic Map
9 Topographic Map
10 politics Map
11 navigation Map
12 how a map is made Surveying- The first step in do a map is to complete a field survey. Surveyors observe, measure, and also record what they view in a particular area. Many data for maps now is gathered by far sensing. Satellites are supplied a lot of to carry out Geographic data.
13 species of Satellites The two significant satellites used are Landsat and also GOES. Landsat is a collection of satellites the orbit more than 100 miles over earth. Each time a satellite makes an orbit, it picks up data in an area 115 mile wide. Landsat can scan the entire planet in 16 days.
14 Landsat Satellite Our very own state the Utah as seen from the Landsat Satellite native space. What go this map show you about Utah?
15 walk Geostationary Operational atmosphere Satellite (GOES) is a weather satellite. This satellite flies in sync through the earth rotation. By act so, it constantly views the very same area. The gathers photos that are helpful in forecasting the weather.
16 GOES image of the U.S.A.
17 GIS Geographical information Systems or GIS stores information about the human being in a digital database. GIS has the ability to combine information indigenous a variety of sources and also display that in methods that permits the user come visualize the use of room in different ways. Maps v special features are made through this system.
18 GPS global Positioning Satellite or gps has the ability to call you exactly where you are on the earth’s surface. 24 satellites called Navstars offer users latitude, longitude, altitude and time on a handheld receiver. Has actually anyone geo-cached before?
19 activity Look at 2 maps in the room. Price the complying with questions: What form of map is it? (Topographic, Political) to you, what is the most vital feature top top the map? (your very own opinion) Why carry out we do maps? talk to one other human being in the class. Compare her answers and also then phone call me i m sorry map you feeling is much better topographical or political.
