Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Remote sensing can be used to collect data on a variety of environmental factors, such as land cover, vegetation, and water quality, which can be used to assess their impact on health. It can also be used to track the movement of disease vectors, such as mosquitoes and ticks, and to monitor the spread of infectious diseases.

Multiple choice

What is the role of remote sensing in geospatial technologies for health and disease surveillance?

  1. To collect data on environmental factors that may influence health

  2. To track the movement of disease vectors

  3. To monitor the spread of infectious diseases

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Remote sensing is a powerful tool for geospatial technologies for health and disease surveillance. It can be used to collect data on environmental factors that may influence health, track the movement of disease vectors, and monitor the spread of infectious diseases. This information can be used to identify areas with high risk of disease transmission, target interventions to specific populations and locations, and evaluate the effectiveness of disease control measures.

Multiple choice

Which of the following is NOT a common method used in wildlife research?

  1. Direct observation

  2. Radio telemetry

  3. Camera trapping

  4. Remote sensing

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Remote sensing is not typically used in wildlife research as it involves the collection of data from a distance, which may not provide detailed information about individual animals or their behavior.

Multiple choice
