ORIENTAÇÃO CARTOGRÁFICA

Summary

In this video, the host, Tio Toni, introduces the basics of orientation using the famous compass rose. He explains the four cardinal points (North, South, East, West) and their corresponding abbreviations in both Portuguese and English. The video then covers the intercardinal points (e.g., Northeast, Southeast) and secondary intercardinal points (e.g., North-Northeast, South-Southwest). With practical examples, Toni explains how to use the sun’s position to orient oneself in real-world situations, like finding your direction in the wilderness. He concludes by encouraging viewers to practice and share the video to help grow the channel.

Takeaways

• 😀 The compass rose (rosa dos ventos) divides directions into three main categories: cardinal points, collateral points, and sub-collateral points.
• 😀 Cardinal points are the four main directions: North (N), South (S), East (E), and West (W).
• 😀 Each cardinal point is separated by 90° from one another, creating a full 360° circle.
• 😀 Collateral points are intermediate directions, found halfway between the cardinal points, including Northeast (NE), Southeast (SE), Southwest (SW), and Northwest (NW).
• 😀 Collateral points are 45° apart from one another.
• 😀 Sub-collateral points are derived from combining a cardinal point and a collateral point, offering even more precise orientation.
• 😀 For example, North-Northeast (NNE) is the combination of North and Northeast, and similarly for other sub-collateral points like East-Northeast (ENE).
• 😀 Knowing the cardinal and collateral points helps with navigation, especially in situations where you don't have a precise direction.
• 😀 In practical scenarios, like being lost in nature, you can use the sun's position to determine direction: the sun rises in the east and sets in the west.
• 😀 To orient a map in real life, you always point the map’s north to the actual north, ensuring correct navigation during travel or emergencies.

Q & A

What are the four cardinal points mentioned in the video?

The four cardinal points mentioned are North (N), South (S), East (E), and West (W).

How are the intercardinal points (also known as colaterals) determined?

Intercardinal points are formed by dividing the cardinal points in half, creating points at 45-degree angles. For example, North + East equals Northeast (NE).

How do you represent the direction East in both Portuguese and English?

In Portuguese, East is represented by the letter 'L', but in English, it is represented by the letter 'E'.

What are the points formed by combining cardinal and intercardinal points (known as subcardinal points)?

Subcardinal points are formed by combining a cardinal point with an intercardinal point. For example, North + Northeast creates North-Northeast (NNE).

How do you use the cardinal points for orientation when lost in nature or a desert?

You can use the position of the sun: your right arm should point to the East (where the sun rises), and your left arm should point to the West (where the sun sets), allowing you to determine North and South.

How many cardinal points are there?

There are four cardinal points: North, South, East, and West.

What is the significance of the 90-degree separation between cardinal points?

The 90-degree separation between cardinal points indicates the angular distance between each direction, creating a complete 360-degree circle of orientation.

What is the abbreviation for the Southeast direction?

The abbreviation for Southeast is 'SE'.

What should you do when orienting a map in the field?

To orient a map, you should point the map's North to the actual North in the field. This is usually indicated on the map's legend.

Why is understanding the cardinal, intercardinal, and subcardinal points important?

Understanding these points helps in navigation and orientation, especially when you're in an unfamiliar location, whether in a city, forest, or desert.
