Abstract: A computing system is configured to generate a map-viewing interface including a display window visually presenting one or more display layers associated with a mapping site therein. Each of the display layers corresponds to a graphical representation of at least one structure and/or utility present at the mapping site and each of the display layers is associated with geo-positional data to establish a relative position of each of the display layers within the display window. A file tag is displayed within the display window of the map-viewing interface and is associated with a file accessible to the computing system and including data relating to one of the structures and/or utilities present at the mapping site. The file is associated with geo-positional data to establish a position of the file tag within the display window relative to each of the display layers instantaneously being visually presented within the display window.
