    • Methods and apparatus for facilitating detection of a presence or an absence of at least one underground facility within a dig area. Source data representing one or more input images of a geographic area including the dig area is electronically received at a first user location, which may be remote from the dig area. The source data is processed so as to display at least a portion of the input image(s) on a display device at the first user location. One or more indicators are added to the displayed input image(s), via a user input device associated with the display device, to provide at least one indication of the dig area and thereby generate a marked-up digital image. In one example, the indicator(s) is/are added to the displayed input image(s) without acquiring geographic coordinates corresponding to the indicator(s).
    • 用于便于检测挖掘区域内至少一个地下设施的存在或不存在的方法和装置。 代表包括挖掘区域的地理区域的一个或多个输入图像的源数据在可能远离挖掘区域的第一用户位置被电子地接收。 处理源数据以便在第一用户位置的显示设备上显示输入图像的至少一部分。 通过与显示设备相关联的用户输入设备将一个或多个指示符添加到所显示的输入图像,以提供挖掘区域的至少一个指示,从而生成标记的数字图像。 在一个示例中,指示符被添加到所显示的输入图像,而不获取对应于指示符的地理坐标。

In one example, the indicator(s) is/are markings that indicate a point, line, and/or path. The indicator(s) may provide a reference for a locate operation or an area of planned excavation. A description, such as of a path to be followed during the locate operation or of an area of planned excavation, may be provided with reference to the indicator(s).
