Greenway is equipped with a staff of Professional Surveyors and Professional Engineers licensed in Virginia and West Virginia. We have more than 35 years of experience working in the Shenandoah Valley and have established an extensive client base throughout Virginia and West Virginia.
Our field crews work quickly and efficiently using the newest technologies including static and real time kinematic GPS . We work together with our clients, listening to your needs in order to accomplish your goals. Our goal is a high level of professionalism and attention to detail. We strive to keep you informed of the status of your project every step of the way.
Total Station Surveying
A Total Station is an electronic/optical instrument used in modern surveying that integrates an electronic theodolite (transit) with an electronic distance meter (EDM) to read slope distances from the instrument to a particular point.
Coupled to a digital data-logger the measurements, together with point codes and attribute information assigned by the surveyor, can be downloaded into a surveying, mapping database or a program. Total stations have become the highest standard for most forms of construction layout.
Global Positioning Systems
When used by skilled professionals, GPS provides surveying and mapping data of the highest accuracy. GPS-based data collection is much faster than conventional surveying and mapping techniques, reducing the amount of equipment and labor required. A single surveyor can now accomplish in one day what once took an entire team weeks to do.
GPS supports the accurate mapping and modeling of the physical world — from mountains and rivers to streets and buildings to utility lines and other resources. Features measured with GPS can be displayed on maps and in geographic information systems (GIS) that store, manipulate, and display geographically referenced data.
LIDAR, an acronym for Light Detection and Ranging, produces a “cloud of points” each with a survey accurate horizontal location and vertical elevation. Providing a full 360° x 270° field-of-view, High Definition Surveying (HDS) produces the data for 3D digitalizing technology and 3D modeling for surface reconstruction, reverse engineering, 3D animation, and inspection. The product, is a robust, accurate 3D representation of the surveyed site that can be mined for a variety of applications.
Utilizing state of the art software, point clouds are processed, texturized, and integrated to produce a complete 3D model of the scanned site. Point data and streaming interactive video of the scanned site can be viewed utilizing an internet or intranet website or point data can be processed and exported for 3D rendering.
Unmanned Aerial Systems (UAS) Topography & Imaging
UAS Topography and imaging are high technology products created by low-altitude acquisition and compilation of 3-dimensional spatial data recorded by our aerial platforms.
Our Unmanned Aerial Systems
Greenway Engineering employs two UAS platforms for obtaining aerial imagery. Both platforms are battery powered and manufactured by senseFly®.
The Albris UAS is a four-rotor vertical take-off and landing drone that can switch between capturing high resolution still, thermal and video imagery during the same flight, without landing to change cameras. Thanks to its unobstructed field of view and its head’s 180 degree vertical range of motion, we can capture clear, stabilized imagery ahead of, above and below the drone.
With the Albris UAS we can perform high-resolution topographic mapping and feature mapping of a site’s highly inclined and vertical surfaces. The high-resolution aerial imagery can be transformed into full 3D models of buildings and small/medium-sized infrastructure.
Using the Albris we can examine and document surfaces and objects in high-resolution for:
- Bridge, pipe & tower inspection
- Plant inspection & documentation
- Stockpile volume calculation
- Construction monitoring
- Archaeological mapping
- Solar panel hotspot detection
