Capture High-Accuracy Data with Laser Mapping

by TNyland 5. June 2019 07:24

Technology is influencing our world to become a more efficient, safe, and precise environment. The progression of tech devices has created a pathway for us to increase our daily output and complete our tasks more efficiently. By incorporating various types of technology into our everyday lives, we are altering the way we, and future generations, are going to live and work. Becoming increasingly dependent on technology to aid us in both our personal and professional worlds, we have provoked geospatial industries to be pushed farther by demanding engineered devices that allow us to establish a stable connection in GNSS impaired environments.

The 21st century is on the tipping point of having four fully operational systems in place. Yet, many still wonder how we manage to stumble into places where our tech lacks a connection. A GNSS impaired environment is caused by an obstruction of the satellite signal. Obstructions can include buildings, terrains, or any man or earth made object that disrupts the signal. GNSS satellite signals can be compared to a 50-watt lightbulb, making it a weak, easily interruptible signal.

The need for real-time high-accuracy GNSS positioning is growing. Regulatory requirements on spatial data accuracy is rapidly increasing, and within some industries less than the utmost precision is acceptable. While highly accurate horizontal and vertical data is achievable in some areas, the demand for high-accuracy positioning has driven us to innovation and collaboration of devices to reach centimeter accuracy where GNSS will not work.

Driving Innovation
Achieving precision accuracy locations of hard-to-reach assets created an industry demand for complete solution. Eos Positioning Systems, Inc®, Esri®, and Laser Technology, Inc®, came together to create the world’s first Laser Mapping Offset workflow within the Esri Collector for ArGIS®. Modifying areas of the hardware and software to make this Laser Mapping Offset solution compatible with iOS devices, so you can Bring Your Own Device (BYOD), to achieve high-accuracy measurements, with the hardware you already have.

The Esri portion of this solution was tailored to use Collector® for ArcGIS®. Check out this ArcGIS blog from Esri on how you can use ArcGIS to capture high-accuracy data using a GPS or GNSS receiver. Discover who benefits from high-accuracy, what it is, and how to take advantage of it via Collector®.

New video: Capture high-accuracy data with Collector

Combined with Collector for ArcGIS, Eos® Arrow® Gold GNSS Receiver, is the first high-accuracy iOS, Android®, and Windows Bluetooth® receiver to implement all four global constellations, three frequencies, and satellite-based RTK augmentation.

Laser Technology’s TruPulse Laser Rangefinders easily integrate into Eos Tools Pro app, or your existing GIS solution to capture repeatable, 3D, highly accurate measurements without needing to occupy every data point. The most highly valued benefit of laser mapping is having the ability to occupy a single, convenient, and safe location with the freedom to map as many assets as you can see. When you use your high-accuracy GPS/GNSS device, everything you collect is based off these precise control points. LTI’s seamless integration allows you to integrate to practically any system and workflow!

The Power of Three: Laser Mapping Offset Routines

The combination of these powerful solution helps eliminate mistakes by capturing accurate dimensional measurements and automatically entering them in as attribute data. This solution streamlines your workflow efficiency and maintains RTK-level accuracy where you traditionally have not been able to before.

Eos Tools Pro has three Laser Mapping Offset routines:

  1. Range-Range
  2. Range-Backsight
  3. Range-Azimuth

To learn more in-depth about these routines, see Eos® Laser Mapping Integration.

In addition, enjoy these laser mapping videos that take you through the full details, step-by-step, of the world’s first and only laser rangefinder mapping solution for Collector for ArcGIS®!

For more information on any of these solutions, please contact LTI.

If you want to check this solution out first hand, LTI will be attending the AWWA ACE19 conference on June 9th-12th. When you stop by booth 3907, you can learn more about laser mapping offsets within the ArcGIS Collector workflow for infrastructure data collection, capturing the location of water values with centimeter accuracy!
