Using DigiTerra Explorer with cable locator and GPS


Components of DigiTerra’s comprehensive GIS solution

  1. 3M Dynatel or Leica DIGICAT cable locator system
  2. Magellan MobileMapper CX (CE) GPS receiver
  3. DigiTera Explorer field data collection and mobile GIS software

An integrated solution step-by-step

01 Placing the marker balls: As a new water or sewer line is placed, marker balls are placed along the pipeline and at each feature and change in the route, including pipe deflections, Ts, junctions and service points. By using a portable marker locator, important details will be programmed into the marker memory just before it goes into the ground; such as the pipe type and size, the year it was installed, fitting type, and depth below the surface.

02 Finding the marker balls: Later, when a locator sends out a search signal, the buried marker responds with stored data, which is displayed on the locator panel. This underground utility marking process that allows to remotely locate and identify facilities by means of buried markers and remote locators.

03 Connecting cable locator and GPS receiver: Connect 3M Dynatel M-iD or 1420-iD cable locator via RS-232 cable (or Leica DIGICAT200 GIS via Bluetooth) to MobileMapper CX GPS receiver, equipped with DigiTerra Explorer software. Each time, when the cable locator identifies a marker, also the GPS position will be recorded.

04 Integrated mobile mapping: By pushing a single button, GPS position and all information stored in the memory of the marker will be transferred to DigiTerra Explorer. You can immediately see all relevant geographical information along with the details stored in the marker on the digital map.


With DigiTerra Explorer, you can locate cables, store information from the markers and update digital maps at the same time without returning again to the same place. As a result, you can save up to 75% time compared to traditional paper-based recording.

Besides handy features, you can also benefit from the flexibility of DigiTerra Explorer: when recording the information stored in the marker, you can directly save the map layers in standard ESRI Shape or Mapinfo MIF file formats. When using a background map prepared in your CAD system, you can directly load it in Autodesk DXF format.

At the end of the day, map layers and attributes can be downloaded from the handheld PDA to the desktop version of DigiTerra Explorer fur further analysis or can be added to an existing GIS database. By doing so, marker data will become part of a comprehensive and integrated GIS solution.
