Which technology is typically used to locate and map physical items on a site?

GPS, or Global Positioning System, is the technology commonly used to locate and map physical items on a site. This system provides precise location data anywhere on Earth, allowing users to determine the coordinates of specific points accurately. GPS operates through a network of satellites that transmit data to GPS receivers, making it essential for mapping, navigation, and various surveying applications in real estate and environmental monitoring.

In the context of site mapping, GPS is particularly valuable because it facilitates the collection of spatial data regarding the placement and distribution of physical items. For instance, when conducting site surveys, professionals can use GPS to pinpoint the exact locations of trees, structures, or utilities. This geospatial information can then be integrated into site plans and analyses, helping to inform design and management decisions.

While GIS (Geographic Information Systems), georeferencing, and satellite imagery are also important in spatial analysis and visualizing data, they serve different roles. GIS is a system for managing and analyzing geographic information, whereas georeferencing involves aligning spatial data to a coordinate system. Satellite imagery provides broader visual context but does not offer the precise location data that GPS can provide on the ground level.
