Collecting and Converting Two-Dimensional Utility Mapping to Three-Dimensional

Assigning depth or elevation values to existing utility mapping is becoming more pervasive as we move from a 2-D CAD design platform to 3-D platforms, whether they be CAD or GIS based. 3D data depiction allows for a robust visualization of mapping elements that can benefit virtually all aspects of a project’s development. Many times we are forced to make judgments or assumptions on the presence or location of a utility, since these utilities are not exposed and therefore able to be directly observed and measured. CI/ASCE 38-02, “Standard Guideline for the Collection and Depiction of Existing Subsurface Utility Data, uses a system of Utility Quality Levels that addresses primarily the horizontal component of a utility’s location. Adding the z component to utility mapping data is not trivial. We use a variety of sources for these judgments. It is important to document the sources for these judgments. This paper discusses source information and documentation issues.
