Name one method of data collection used in GIS.

• A. Remote sensing
• B. Data visualization
• C. Field surveys
• D. Database management

Answer: (C)

Field surveys are a primary method of data collection used in GIS because they involve gathering data directly from the environment. This method allows researchers to collect accurate, real-time data about geographic features, conditions, and phenomena, often utilizing various instruments or tools like GPS devices, cameras, or measuring tapes. Field surveys can provide rich qualitative and quantitative information necessary for creating and updating spatial databases, which are fundamental for detailed analysis and decision-making in GIS. While other methods like remote sensing involve data collection through aerial or satellite images, field surveys are distinctive in that they offer firsthand data collection, which can validate or enhance the information obtained from remote sources. This direct interaction with the geography being studied allows for a depth of understanding that can be critical in various GIS applications, including urban planning, environmental monitoring, and resource management.
