Aerial Mapping & LiDAR
You have a choice when it comes to collecting geospatial data. Traditional photogrammetry, UAS/drone, and LiDAR technologies all have their distinct advantages, but the trick is in knowing which is best for your project. As nationally preferred mapping consultants, we’re here to make sure your needs are met.
Current, georeferenced, highly accurate, and scalable, traditional photogrammetry is best for assessing new or potential development options. In one flight pass, it can collect imagery covering a much wider swath than LiDAR; plenty of area that aids designers and clients in assessing and planning public and private infrastructure projects.
Whether we utilize traditional aerial photogrammetry or drones, our teams ensure that the aerial photography is registered to ground coordinates by collecting GPS-based photo control and check points on the imagery in order to meet our clients’ specifications.
Nimble and cost-effective, Unmanned Aerial Systems (UAS)/drones are a rapid deployment solution for gathering site data, communicating site design, and monitoring construction activities. With the ability to perform commercial drone flights across the country, our FAA Part 107 certified pilots deliver safe operations and quality end results. They are equipped with fixed-wing and rotary UAS with and without onboard RTK GPS.
Working together, our pilots, certified photogrammetrists, and licensed land surveyors by providing the necessary tools and products to meet their goals:
- Digital Elevation Models (DEMs)
- Digital Terrain Models (DTMs)
- Contour Maps
- Point Clouds
Sometimes you need data. Sometimes you need detail. Sometimes you need both. LiDAR is the go-to tool when you have areas of dense vegetation or complex above-ground improvements and you need heavy detail of current conditions. The high-density, georeferenced point clouds are excellent for providing teams with in-depth looks at existing features, clearance issues and infringement identification, and vegetation management.
Whether by fixed-wing aircraft or Unmanned Aerial Systems (UAS), Westwood’s teams have a choice in data capture for your projects. Capturing LiDAR data through the air allows our teams to quickly gather data over large, complex areas. Our aerial LiDAR data is quickly processed and fully integrated into our workflow to support your projects through due diligence, design, and construction.
Terrestrial LiDAR, or 3D scanning, is the way to go when it is necessary to acquire enhanced detail within a project. Westwood’s teams are equipped with the latest scanning equipment and software to support an endless array of use cases for our clients. Once collected, our point cloud data can be delivered as-is or integrated into CAD, REVIT, and other design drafting platforms.
LiDAR data capture and processing examples include:
- Topographic surveys
- As-built or record surveys
- Structural analysis
- Architectural support
This virtual walk-through features an unprocessed point cloud from a terrestrial LiDAR scanning session. The raw point cloud is often the starting point for many deliverables prepared from LiDAR data.
After the initial acquisition, detailed as-built models, scan to BIM models, visualizations, animations, and VR environments can be created to complement project design data.
With several offices and professional expertise in nearly all of the US, we have what it takes to support public infrastructure and private development projects across the country.
