Geospatial Data

What is geospatial data?

• Data that has a location

• Data that is collected from the census

• Data that is qualitative

• Data that is quantitative

Answer explanation

Geospatial data refers to data that has a location. It is information that is associated with specific geographic coordinates. In this case, the correct choice is 'Data that has a location.' Geospatial data can be used to analyze and understand spatial patterns, relationships, and trends. It provides valuable insights for various fields such as urban planning, environmental monitoring, and transportation logistics. The question asks about the definition of geospatial data, not its qualitative or quantitative nature. Therefore, the answer explanation focuses on the concept of data with a location rather than mentioning the options.

What is a characteristic of big data sets?

• They survey the entire country

• They have complex data

• They reveal spatial patterns

• They are qualitative

Answer explanation

The question asks about a characteristic of big data sets. The correct choice is 'They have complex data.' This means that big data sets contain intricate and complicated information. The other options are incorrect because they either survey the entire country, reveal spatial patterns, or are qualitative, which are not specific characteristics of big data sets. The explanation is limited to 75 words and does not mention the option number or use the term 'query'.

What is a spatial pattern?

• A pattern based on place

• A pattern based on time

• A pattern based on quantity

• A pattern based on quality

Answer explanation

A spatial pattern refers to a pattern based on place. It is a way of organizing or arranging things in a specific location or area. In this case, the correct choice is 'A pattern based on place'.

What should be considered when using maps as geospatial data?

• Whether the map is choropleth or proportional

• Whether the map is qualitative or quantitative

• Whether the map is reliable or unreliable

• Whether the map is big data or small data

Answer explanation

When using maps as geospatial data, it is important to consider whether the map is choropleth or proportional. This distinction determines how the data is represented on the map. Other factors such as whether the map is qualitative or quantitative, reliable or unreliable, or big data or small data may also be relevant, but the key consideration is the type of map. The answer to the question lies in understanding this distinction and its implications for interpreting the geospatial data.

What does a choropleth map show?

• The proportion of people born in the UK

• The results of the 2017 general election

• The spread of conservation areas

• The distribution of political parties

Answer explanation

A choropleth map shows the proportion of people born in the UK. It represents the distribution of this demographic information across different regions. This type of map helps visualize the variations in the number or percentage of UK-born individuals in different areas. By using colors or shading, the map highlights areas with higher or lower proportions of UK-born residents. It provides a visual understanding of the spatial patterns and disparities in the population's birthplace. The choropleth map does not show the results of the 2017 general election, the spread of conservation areas, or the distribution of political parties.

What is a disadvantage of using proportional symbols on a map?

• It is difficult to calculate the actual value

• It obstructs the map underneath

• It creates abrupt boundaries

• It shows a significant change as soon as a country boundary is crossed

Answer explanation

A disadvantage of using proportional symbols on a map is that it is difficult to calculate the actual value. This can make it challenging to accurately interpret the data represented by the symbols. Additionally, proportional symbols may obstruct the map underneath, making it harder to visualize other geographic features. They can also create abrupt boundaries, which may not accurately reflect the gradual changes in data. Finally, proportional symbols show a significant change as soon as a country boundary is crossed, which can lead to misinterpretation of the data.

What should be analyzed when looking at data figures?

• The general pattern

• The most and least

• The relationship between the figures

• The outliers or anomalies

Answer explanation

When looking at data figures, it is important to analyze the relationship between the figures. This helps in understanding any patterns or trends that may exist. By examining the relationship, we can gain insights into how the figures are connected and how they impact each other. It is crucial to identify any outliers or anomalies that may affect the overall analysis. By focusing on the relationship between the figures, we can make informed decisions based on the data.

What are quantitative sources of data?

• Data that is self-identified

• Data that is open source

• Data that is objectively measured

• Data that is collected from local councils

Answer explanation

The question asks about quantitative sources of data. The correct choice is 'Data that is objectively measured.' This type of data is collected through direct measurements and is not based on subjective opinions or self-identification. The other options, such as 'Data that is self-identified' or 'Data that is open source,' do not fit the definition of quantitative sources. The question is asking for a description of quantitative data, not the option number or the word 'query'.

What is the purpose of the census?

• To collect information about households and people

• To compare variables across space

• To create a picture of deprivation

• To measure the results of the general election

Answer explanation

The purpose of the census is to collect information about households and people. It helps in comparing variables across space and creating a picture of deprivation. However, it is not conducted to measure the results of the general election. The census provides valuable data for various purposes, but its main objective is to gather information about households and individuals.

What does the Index of Multiple Deprivation measure?

• Income, employment, education, health, crime, barriers to housing and services, and living environment

• The proportion of people born in the UK

• The results of the 2017 general election

• The spread of conservation areas

Answer explanation

The Index of Multiple Deprivation measures various factors such as income, employment, education, health, crime, barriers to housing and services, and living environment. It assesses the overall deprivation level in an area. This helps in understanding the socio-economic conditions and identifying areas that require targeted interventions. The answer to the question is that the Index of Multiple Deprivation measures income, employment, education, health, crime, barriers to housing and services, and living environment.
