Which of the following is a common method for collecting geospatial data?

Remote sensing is a common and widely utilized method for collecting geospatial data. This technique involves the acquisition of information about an object or area from a distance, typically using satellite or aerial imagery. Remote sensing enables analysts to gather data over large areas quickly and efficiently, capturing various physical and environmental features such as land use, vegetation cover, temperature variations, and much more. This method is crucial for applications such as environmental monitoring, urban planning, and disaster management, as it allows for real-time or periodic assessments of geographical areas.

The other options, while they can contribute to gathering data, are not primarily focused on capturing geospatial information in the same comprehensive and systematic manner as remote sensing. For instance, focus groups and surveys are more qualitative and rely on human opinions or experiences, which do not provide precise spatial data. Public records serve as valuable background information but are typically not generated specifically for mapping or spatial analysis. Hence, remote sensing stands out as the most relevant method for the direct collection of geospatial data.
