Question

Приведите пример фоновой картограммы. Объясните.​

Answer 1

Ответ:

Вид картограммы, на которой штриховкой различной густоты или краской разной степени насыщенности изображают интенсивность какого-либо показателя в пределах территориальной единицы.

Известны три вида фоновых картограмм:

1. Простая.

2. Дазиметрическая.

3. Неклассифицированная.

1. Простая:

Для создания простой фоновой картограммы устанавливают значение показателя для каждой территориальной единицы и разбивают на категории или классы.

2) Дазиметрические фоновые картограммы менее распространены, они были разработаны для преодоления некоторых ограничений простых фоновых картограмм.

3) Неклассифицированная

Править

Неклассифицированные фоновые картограммы были предложены Вальдо Тоблером в 1973 году, но оставались мало распространены до наступления эпохи компьютеров. В неклассифицируемых фоновых картограммах каждому значению показателя соответствует отдельная текстура или краска

Answer 2

Background on Cartograms

A cartogram is a type of map that distorts the size or shape of geographic regions to represent a specific variable or data set. Unlike traditional maps, where the size of regions is determined by their actual land area, cartograms resize regions based on the data being represented. This allows for a visual representation of data that can highlight patterns or relationships that may not be immediately apparent on a regular map.

Cartograms can be used to represent a wide range of data, such as population, GDP, election results, or any other variable that can be associated with geographic regions. By resizing the regions, cartograms provide a way to visually compare and analyze data across different areas.

Example of a Cartogram

Let's consider an example of a cartogram that represents the population of different countries. In a traditional map, the size of each country would be proportional to its land area. However, in a cartogram representing population, the size of each country would be proportional to its population.

Here is an example of a cartogram representing the population of different countries:


In this cartogram, the size of each country is distorted to reflect its population. Larger countries with higher populations appear larger on the map, while smaller countries with lower populations appear smaller. This allows for a quick visual comparison of population sizes across different countries.

Explanation

Cartograms are created by using specialized software or algorithms that calculate the distortion needed to resize the regions based on the data being represented. The process involves assigning a weight or value to each region based on the data, and then resizing the regions accordingly. The resulting map provides a visual representation of the data in a way that is easier to interpret and analyze.

Cartograms can be useful in various fields, including geography, economics, sociology, and politics. They can help researchers and decision-makers understand spatial patterns, identify trends, and make informed decisions based on the data represented.

In conclusion, a cartogram is a type of map that distorts the size or shape of geographic regions to represent a specific variable or data set. It provides a visual representation of data that allows for easier comparison and analysis. An example of a cartogram is one that represents the population of different countries, where the size of each country is distorted to reflect its population.
