Top 10 Questions for Remote Sensing Surveyor Interview

1. Explain the principles of remote sensing and how it is used in surveying?

Remote sensing is the science of acquiring information about an object or phenomenon without making physical contact with it. In surveying, remote sensing is used to collect data about the Earth’s surface, atmosphere, and oceans. This data can be used to create maps, identify land use patterns, monitor environmental changes, and manage natural resources.

• The principles of remote sensing are based on the interaction of electromagnetic radiation with the Earth’s surface.
• When electromagnetic radiation strikes an object, some of the radiation is absorbed, some is reflected, and some is transmitted.
• The amount of radiation that is absorbed, reflected, and transmitted depends on the wavelength of the radiation and the properties of the object.
• By measuring the amount of radiation that is absorbed, reflected, and transmitted, it is possible to identify the object and determine its properties.

2. What are the different types of remote sensing data and how are they collected?

Types of remote sensing data

• Optical data: Optical data is collected by sensors that measure the amount of visible light and infrared radiation that is reflected or emitted by an object.
• Radar data: Radar data is collected by sensors that emit microwave radiation and measure the amount of radiation that is reflected back to the sensor.
• Lidar data: Lidar data is collected by sensors that emit laser pulses and measure the amount of time it takes for the pulses to travel to an object and back to the sensor.

How remote sensing data is collected

• Remote sensing data can be collected from a variety of platforms, including satellites, aircraft, and drones.
• Satellites are the most common platform for collecting remote sensing data.
• Satellites orbit the Earth and collect data as they pass over the Earth’s surface.
• Aircraft and drones are also used to collect remote sensing data.
• Aircraft and drones can be used to collect data at higher resolutions than satellites.

3. What are the advantages and disadvantages of using remote sensing for surveying?

Remote Sensing Surveyors are responsible for collecting and interpreting data from various sources, including satellite imagery, aerial photography, and LiDAR (Light Detection and Ranging). They use this data to create maps, identify landforms, and monitor changes in the environment.

1. Data Collection and Analysis

Remote Sensing Surveyors collect data from a variety of sources, including:

• Satellite imagery
• Aerial photography
• LiDAR (Light Detection and Ranging)

Once they have collected data, they analyze it to identify landforms, vegetation, and other features. They also use this data to monitor changes in the environment, such as deforestation or urban expansion.

2. Map Creation

Remote Sensing Surveyors use the data they collect to create maps. These maps can be used for a variety of purposes, including:

• Land use planning
• Environmental monitoring
• Navigation

3. Presentation and Interpretation

Remote Sensing Surveyors often present their findings to clients or other stakeholders. They may also be asked to interpret the data they collect and provide recommendations based on their findings.

4. Research and Development

Remote sensing is a rapidly evolving field. Remote Sensing Surveyors must stay up to date on the latest technologies and techniques. They may also be involved in research and development projects to improve the accuracy and efficiency of remote sensing methods.
