Gr 8&9 Geography | Basic Mapwork | Lesson 1/5 | Types of Maps

Brief Summary

This video introduces the fundamentals of maps and different types of maps used to convey various information in a straightforward and visual way. It covers political, physical, and thematic maps, as well as orthophoto and topographical maps. The video also touches on essential map work concepts like latitude and longitude, map scales, time zones, and aerial photos.

  • Political maps depict borders, boundaries, capital cities, and major roads.
  • Physical maps illustrate natural features like rivers, lakes, and mountain ranges.
  • Thematic maps display data about specific themes or topics, such as land use or natural resources.
  • Topographical maps show both man-made and natural features.
  • Orthophoto maps combine aerial photos with map data.

Introduction to Maps

The lesson introduces maps as tools for conveying information in a visual way, similar to treasure maps but for grown-ups. Maps teach about the world by displaying country sizes, areas, geographic features (mountains, rivers, buildings), and distances between places, scaled down to fit on paper. They also depict the distribution of objects, sediment patterns, population concentrations, and vegetation.

Types of Maps: Political Maps

Political maps depict borders of countries, provincial boundaries, capital cities, important towns, major roads, airports, and other significant places. They show legal, jurisdictional, political, or administrative boundaries, helping people understand the geography of the world. These maps are frequently used to depict Census Data and election results.

Types of Maps: Physical Maps

Physical maps depict the natural features of the Earth, such as rivers, lakes, and mountain ranges. They include a color key that shows the height of areas above sea level, with sea level as the zero point. These maps also show deserts, marshes, swamps, and deltas. Physical maps are useful for studying the natural environment and understanding how physical features interact, such as how mountain ranges affect weather patterns and how rivers shape the landscape.

Types of Maps: Thematic Maps

Thematic maps display data about a specific theme or topic, such as land uses and resources. They use small images or symbols to represent concepts like minerals, mines, industries, power stations, transport routes, crop locations, and animal habitats. Thematic maps are used to analyze spatial patterns and relationships between different phenomena, such as population density and urban development, or the distribution of natural resources. They can also study the impacts of human activities on the environment, such as pollution sources or wildlife habitats.

Topographical Maps and Orthophoto Maps

Topographical maps show all man-made and natural features. An orthophoto map is a combination of an aerial photo and a map, typically covering a small section of a topographical map, demarcated by a red square.

Durban Fly Through

The video includes a fly-through simulation of Durban, encouraging viewers to identify locations on the map and compare them with the simulation. The fly-through highlights features such as a golf course and the stadium.

Basics of Map Work

Latitude and longitude lines are used to locate points on the Earth's surface. Latitude lines run horizontally and are measured in degrees north or south of the Equator. Longitude lines run vertically and are measured in degrees east or west of the Prime Meridian (Greenwich Meridian). The Earth's angle of axis, about 23.5 degrees, causes the seasons due to changing sunlight angles. Map scales refer to the relationship between distances on the map and actual distances on the ground. Large-scale maps show small areas in great detail, while small-scale maps show larger areas with less detail.

Time Zones and Aerial Photos

Time starts at the Greenwich Meridian (0 degrees longitude), with a one-hour change for every 15 degrees. The International Date Line (IDL) at 180 degrees longitude is where the day changes. Traveling westward requires setting clocks back, while crossing the IDL requires adjusting by 24 hours. Aerial photos, taken from satellites or airplanes, include vertical and oblique types. Oblique photos are taken from an angle (bird's eye view), while vertical photos are taken from directly above. These images are used to create maps and study the Earth's surface.

Conclusion

The lesson provides an overview of important map types, particularly topographical maps, which will be focused on in future lessons. Viewers are encouraged to check the video description for a self-marking assessment and Google Slides to check their understanding.

0:00 [Music] foreign [Music] you're welcome to call me any of those I will be covering a couple of lessons over map work with you guys I'm very happy to be doing this lesson for you welcome to my Tuma Mina teaching maps are awesome if a picture is worth a thousand words maps are worth ten thousand more they are jam-packed with loads of information um excuse me editor the last three should have not been there they are part of a game

0:50 today we'll be learning about the fundamentals of maps as well as learning about different types of maps maps are about conveying all types of information in a straightforward and visual way do you remember when you were a kid and you played around with treasure maps what do they give you information right so do maps for grown-ups they give all types of information they teach about the World by displaying country sizes they can give us the area which is the area of the country and forms and locations of geographic features so for example where the mountains are where the rivers are and where buildings are Etc and distances between places so these

1:36 systems are generally scaled down to fit into a sheet of paper maps can depict the distribution of objects on Earth so we are able to tell sediment patterns from the earth so when you're in grade 10 11 and 12 you'll learn about different sediment patterns right they can tell us where most people are concentrated and which areas have the most vegetation there are many reasons why maps are so important and I think that they are worth a class discussion so if you're in class right I'm going to have four headings pop up on the screen and you're welcome to just take a quick pause to discuss some of the headings that come up in this lesson we'll introduce the following Maps a physical map

2:22 a political map a thematic map an orthophoto and a topographical map let's start off with the political map a political map is a map that looks like the one I have here we can use political maps as I've said earlier on to depict different types of information we can depict borders of countries we can look at provincial boundaries we can look at Capital Cities and other important towns we can have major roads like the N1 and N2 in Cape Town we can have airports or other spatial and significant places political maps show legal jurisdictional political or administrative boundaries

3:08 these help people understand the geography of the world these maps are frequently used to depict Census Data like the one we had in 2022 and even election results like the ones we're having in 2024 foreign [Music] now we're transitioning from political maps going into physical maps physical maps depict the natural features of the Earth so the things we see physically that come from the Earth we can use physical maps to see rivers

3:54 lakes and other water bodies we're also able to see mountain ranges right it also has a color key that shows the height of areas above sea level remember that our zero in maps is sea level not zero meters we can also see deserts marshes swamps and Deltas from a physical map physical maps are useful for studying the natural environment and understanding how physical features interact with one another for example we're able to see how mountain ranges affect the weather to remember in climatology grades you learned about autographic grain we are able to see if an area gets this type of rain from

4:40 physical maps we are also able to see how Rivers shape the landscape on which they flow [Music] foreign [Music] foreign [Music] Maps display data about a specific theme or topic the magic Maps looks like the one I have here they are able to give us information about specific land uses and resources

5:28 the Matic Maps can use small images of symbols to express some of these Concepts such as minerals and mines they can also show us Industries and power stations they can also show transport routes and areas where particular crop is formed they can also show us areas where a particular type of animal is formed thematic maps are quite powerful they can be used to analyze different spatial patterns and relationships between different phenomena such as the relationship between population density and Urban Development or the distribution of Natural Resources across the region these Maps can also be used to study the impacts of human activities on the environment such as the distribution of pollution sources or even the location

6:14 of wildlife habitats foreign [Music] most important for your high school career topographical maps and author photos a topographical map is a map that shows all the man-made and natural features like the one we have right here we will go into more detail in our next

7:00 lesson about this map an author photomap is a combination of an area photo which is a photo normally taken by an airplane and a map this map normally covers a small section of a topographical map that section is normally written as a demarcated area within a topographical map it is normally drawn with a little red square on your topographical map okay Learners now for you to make sense of these Maps on your left is the mat and on the right is the VR pilot tool travel through the swamped area to show you the areas and features that are represented on the map and hopefully this will help you conceptualize it

7:47 I always wanted to go to Durban Leo please take us through Durban speaking I will gladly head over to Durban [Music] foreign now as I fly through Durban try to identify me on the map [Music] and compare the map with the simulations that you see in this fly through can you identify this place [Music]

8:40 okay foreign [Music] we've got a golf course and let's head over and end at the Stadium [Music] foreign [Music]

9:31 Maps can be used to give our absolute location using latitude and longitude guess what this video happens to be sponsored by the latitude hotel in Cape Town [Music] now I'm going to run through some of the basics of map work that are very important to understand before going into detail about Maps I'll be doing this in great speed so be sure to watch it again if you missed it the first time I'm going to cover this list in less than 90 seconds so let's do it firstly latitude and longitude lines are used to help locate points on the Earth's surface latitude lines run

10:17 horizontally around the globe and are measured in degrees north or south of the Equator longitude lines run vertically and are measured in degrees east or west of the Prime Meridian or Greenwich Meridian depending on how your primary school teacher called it in addition we have the Earth's angle of axis which is the angle between the Earth's rotational axis and a line perpendicular to the plane of the ecliptic this angle is currently about 23.5 degrees which is why we have the seasons on Earth as the angle of the sunlight changes throughout the year next we have the concept of map scales

11:03 maps come in different scales which refer to the relationship between the distance on the map and the actual distance from the ground or in real life large scale Maps show a small area in great detail while small scale Maps show a larger area with less detail for example we have orthophotus and topographical maps as I've mentioned before the author photo normally covers a demarcated area in a topographical map [Music] foreign [Music]

11:50 foreign [Music] and lastly we have the concept of time zones time starts at the Greenwich Meridian which is the zero degrees line of longitude there's a one hour change in time for every 15 degrees at the 180 degrees line of longitude we have the IDL the International Date Line it's where the day changes people traveling Westward around the world must set their clocks back by one hour for every 15 degrees of longitude crossed and forward by 24 hours upon crossing the International Date Line lastly we have images taken from a satellite called satellite images or

12:37 from an airplane called aerial photos we have two types of aerial photos a vertical aerial photo or an oblique aerial photo an oblique aerial photo is generally taken from an angle think of a bird's eye view a vertical one is taken from directly above the features mapped these are images of the earth taken from space or from an aircraft is offset and can be used to create maps and study the Earth's surface in great detail and so grade 8 we've currently reached the conclusion of our lesson now this lesson was just to give you a quick overview of the most important types of maps of course we're not saying these are all types of maps but these are the

13:22 ones you'll interact with as you go in your geography career in our next lesson we'll be zooming specifically into topographical maps as diesel maps that you'll be working with mostly this year and next year now grade 8 tonight remember to check the description of this video down below here you'll find a self-marking assessment and Google Slides it is very important to check your understanding and this assessment will help you do just that thank you so much for watching I wish you all the best for your method and hope to see you next time [Music]
