Mapping underground assets traditionally means: Line locator paints the ground surface near the locate, then a mapper collects the surface paint as a point or polyline.  This method misses all the line locate meta data (frequency, strength,) plus the actual depth of the asset.  And the line locate and GNSS data may be collected days or weeks apart potentially missing significant amounts of data.   

Will share current integrated mapping solution options including: PointMan (Colo DOT right-of-way mandated from Jan 14, 2021), Subsurface Maps, Trimble TerraFlex, Trimble Access, TerraFlow, plus hopes for Esri Field Maps/ Survey123 workflows.  Discuss current line locator options with high accuracy GNSS built-in or adding high accuracy GNSS “puck” antenna’s (30cm, 10cm, 2cm) with line locators to create all-in-one “mapping-locating” solutions.  

We will be discussing Radiodetection (RD) line locators, Trimble and Juniper Systems GNSS mapping hardware during this presentation.
