GPS Laser Offsets

Easily collecting accurate GNSS / RTK data.

Challenges to capturing data

GNSS receivers in mapping are powerful tools, and there are times when even the best tools have limitations. Receivers are designed to compute the location of the antennas, requiring you to occupy a location in order to accurately map a feature. This is not always safe or practical when positioning features such as a manhole in the middle of the street or features which are on private property. Trees, steep terrain or high-rise buildings are also obstructions that block satellite signals.


Offsets: Making the job easier and safer

Measure distance offsets to features by recording both a GPS position and an associated distance and direction to the object of interest in a challenging location.

For example, to record the attributes of a tower that is on the other side of a steep, narrow ravine, use the offset capability to stand and record the position at one side of the ravine then simply record the offset to the tower on the other side. Integrate a laser rangefinder and an electronic compass (providing distance, inclination and azimuth) with your GIS data collection system and eliminate the need to physically occupy every point. Reduce the time and risk involved in gathering field data with laser offsets.

Our TruPulse® laser rangefinders measure vertical angles and horizontal distance, providing highly accurate positioning for 2D data. The addition of an azimuth measurement enables accurate 3D data when needed for your project. LaserGIS® is our term for the offset mapping practices that TruPulse rangefinders can perform.

Streamline your Field Data Collection

By combining TruPulse laser rangefinders with one of many popular GIS data collection apps, you can streamline your field data collection workflows. We’ve made it easy to integrate a TruPulse laser seamlessly into practically any system and workflow.

Benefits of Offsets in GPS Data Collection
  • Collect data easily in GNSS-challenged environments
  • Decrease safety liabilities in dangerous situations
  • Reduce traverse time to objects and total time on site
  • Record distance offsets and attributes for hundreds of features from a single vantage point
Examples of Laser Offset Mapping Applications
  • Objects located in steep terrain
  • Safe recording of data near busy highways
  • Manholes and other features located in the middle of the street
  • When the GNSS signal is blocked by buildings or trees
  • Features which are on private property

LaserGIS Mapping Success Stories

Modern Mapping Project at Woodland Park Zoo

"For lead gardener Dann Block, large trees, exhibit structures, and zoo animals such as lions proved to be significant obstacles to collecting data points for GIS mapping." Insert LaserGIS, and the rest is history.

Eos® Laser Mapping Integration

Eos Positioning Systems, Inc.® (Eos) is the world’s leading provider of GPS/GNSS receivers for the Bring Your Own Device (BYOD) market and the first to integrate with Esri® ArcGIS® Field Maps to allow for laser offsets. Eos brings you affordable, high-accuracy Bluetooth® GPS (GNSS) location to any smart device and provides submeter, sub-foot, and centimeter accuracy.

Arrow Series® GNSS Receivers

Arrow Series® receivers provide survey-grade or submeter positioning via Bluetooth® to any iOS®, Android or Windows device running a data-collection app. The newer Arrow Gold+™ and Arrow 100+™ (plus models) GNSS receivers offer additional GNSS support and have the Eos Bridge Bluetooth® connector built-in.

Eos Tools Pro

Eos Tools Pro is a monitoring utility for the Arrow Series™ receivers from Eos. Eos Tools Pro provides advanced GNSS information such as RMS values, PDOP, Differential Status, and Satellites Tracked and Used, which are critical for submeter and centimeter GIS and Surveying data collection. It is also what makes laser mapping possible within the Esri ArcGIS Field Maps app.

Eos Bridge™

Want to connect a TruPulse 200 or 360° model to an Apple device? The Eos Bridge is a Bluetooth® connector that makes it happen by connecting to our laser rangefinder and your iOS device. Your offset and dimension data can then flow directly into your iOS app, such as Eos Tools Pro.

RTK Laser Mapping

Enhance your ArcGIS Field Maps workflow efficiency with laser integration and maintain RTK-level accuracy where you traditionally have not been able to before. Help eliminate mistakes by capturing accurate dimensional measurements and automatically entering them in as attribute data.
