Reality Capture; Utilizing Technology to increase Revenue with limited Capacity
This session will provide a quick glimpse into how "Reality Capture Technology" significantly increased the revenues of a small land surveying and engineering firm based in St. Louis. TWM's land survey department (now Geospatial Group) transformed itself from being a support service for the engineering disciplines to a self-sufficient leader in billings, profit and technology for the company. Find out how the Geospatial Group successfully leveraged Terrestrial Laser Scanning (TLS) to significantly increase revenue and reinvest that revenue to purchase the latest surveying technological advances while addressing the issues of limited capacity...
Mapping Rural Highway Safety Programs with Small Format Mobile LiDAR - Teledyne
Driving through the rolling mountains of Kentucky makes me think of how the early trailblazers crossed Kentucky for the first time. Feeling the road below dip and turn, my stomach feels the movement just like a rollercoaster at the park. Many people on these roads do not have the same driving enjoyment, but fear that they may meet a large truck along a tight curve. Rural highway safety is a need on every road in Kentucky.
Evolving World of Surveying - WithersRavenel & PrecisionHawk
WithersRavenel, an NC-based Engineering and Surveying company, and PrecisionHawk, the leading provider of commercial drone solutions, joined forces in a partnership to provide top-tier solutions to their clients. With first-hand knowledge of the ever-evolving world of surveying best practices, WithersRavenel and PrecisionHawk spent two years exploring the needs of surveyors in order to create a solution that paired LiDAR capability with an in-depth flight planner for both UAS LiDAR and photogrammetry missions. Now, WithersRavenel is actively flying a UAS LiDAR/Photogrammetry solution for topography and orthophotography applications to support survey and mapping services such as planimetric surveys and 3D feature extraction. Join this session to learn from their experiences throughout this process. You will leave this session with: • An understanding of how WithersRavenel and PrecisionHawk expanded upon their current partnership to create a LiDAR and photogrammetry-based solution specific to surveyors. • A use case-turned-template for future iterations of surveying LiDAR and photogrammetry solutions. • An in-depth look at the specific steps WithersRavenel and PrecisionHawk took to ensure that their solution met the strict standards of surveyors in North Carolina, and across the US. • A comprehensive look at the steps these companies took to build their partnership and provide a unique and relevant solution for their customers. Join WithersRavenel and PrecisionHawk for a presentation and open discussion highlighting land surveying legality/principles, best practices, and quality control procedures for UAS LiDAR and photogrammetry.
Bridging the Gap Between Aerial and Terrestrial Mapping: a Mobile Mapping Case Study
The beautiful hilltop town of Mondovì in the Piedmont region of Italy required a full 3D model of the area surrounding a proposed bridge construction project. A roadway runs on one side of the ravine. On the other side are the winding streets, alleyways, sidewalks, and stairways of the ancient quarter of Borgato. The challenge in capturing a complete 3D model of this large area is obvious; a vast array of varied conditions that are nearly impossible to adequately capture with aerial or terrestrial techniques. An engineering firm hired Italian surveying company GeoMar, an architectural and topographical surveying company, to conduct the survey. Initially, GeoMar conducted an aerial scan (approximately 2.0 square kilometers/0.8 square miles) using Riegl VUX mounted on a helicopter. While the top down field of view from the air provides excellent data in X and Y planes, the ground-level data in the Z plane is incomplete. Information in or around structures and topographic features at ground level are not collected, resulting in a loss of complete 3D structure. To enhance the original aerial base map and essentially "bridge the gaps" in data (pun intended), GeoMar, an early adopter of many geospatial technologies, employed a handheld mobile mapping solution using both vehicle and hand carrying methods. The ground data was collected with GNSS input to correct for drift over large areas and then geo-registered with the aerial data. The result is a complete 3D model of the surveyed area, collected in a fraction of the time by a crew of one and a workflow that convinced this demanding geospatial firm that handheld mobile scanning's time has come.
