Cutting-Edge Technology On Every Project
Terrestrial Laser Scanning
With our RIEGL VZ-400 3D Terrestrial Laser Scanner, Thew Associates can provide static 3D laser scanning services for our clients. We can complete high-definition survey scans of most sites providing comprehensive three-dimensional spatial and elevation data with decreased data collection time and increased cost efficiencies.
- Interior and exterior structure scanning for renovation and restoration
- As-built surveying and mapping
- Topographic surveying and mapping
- Structural deformation monitoring
- 3D point cloud data with RGB assigned color values
- True 3D mapping with digital terrain modeling
- Traditional 2D mapping with elevation data
- Point cloud viewer application capable of extracting measurements
UAV LiDAR
The RIEGL miniVUX-1 LiDAR sensor that Thew Associates’ utilizes is equipped with a RGB camera which allows us to provide a high density colorized point cloud to clients. The general output of a LiDAR sensor is a .LAS file. This file contains vector data for every point within the cloud. Therefore, many different “Layers” of data can be extracted from the .LAS file. These layers can be translated to different types of GIS formats such as 3D Face, 3D Mesh, vectors, TIN’s, DSM’s, DTM’s, break lines, planimetric lines, etc.
- Raw Point Cloud – Attributes include: XYZ, Intensity, Return #
- Classified Point Cloud – Attributes include everything from Raw Point Cloud plus unique classification of buildings, vegetation, powerlines, utility poles, ect.
- Extracted features – Buildings, trees, etc.
- Rasters – Digital Elevation Models, Digital Surface Models, and Intensity rasters.
- Contours (GIS or CAD formats)
- AutoCAD breaklines and feature
UAV Photogrammetry
With the LiDAR sensor integrated with the RGB camera, Thew Associates can deliver high-quality imagery data of a client’s project site. Thew Associates’ UAV pilots can also capture video in areas that are not safely or easily accessible otherwise.
- Orthomosaic
- RGB point cloud
- Digital Surface Model (DSM)
- Digital Terrain Model (DTM)
- Planimetrics
Airborne LiDAR and Photogrammetry
Thew Associates is committed to managing all aspects of a client’s geospatial requirements to include LiDAR and photogrammetry surveying and mapping of larger project sites. We have longstanding relationships with aerial mapping firms whom we partner with to collect the LiDAR and aerial imagery and then manage the data processing in-house.

Remote Sensing FAQ's
What is remote sensing?
Remote sensing refers to the process of collecting information about objects or areas from a distance, usually through the use of satellites, aircraft, or other sensor technologies.
How does remote sensing work?
Remote sensing works by detecting and measuring the electromagnetic radiation reflected or emitted by objects or areas. This data is then analyzed to provide information about various characteristics or objects in the observed region.
What is LiDAR in remote sensing?
LiDAR (Light Detection and Ranging) is a remote sensing technology that uses laser pulses to measure distances between the sensor and the target. It is commonly used to create high-resolution topographic maps, 3D models, and to measure distances and altitudes accurately.
How does LiDAR work?
In LiDAR, a laser beam is emitted towards the target, and the sensor measures the time taken for the laser to return after reflecting off the target. This information is used to calculate the distance between the sensor and the target, allowing for precise mapping or measurement.
Can remote sensing and LiDAR be used in agriculture?
Yes, remote sensing and LiDAR are increasingly being utilized in agriculture. They can be used for precision farming, crop monitoring, soil moisture assessment, detection of diseases and pests, and for optimizing irrigation and fertilizer application.
Are there any limitations to remote sensing and LiDAR?
Yes, there are certain limitations. Cloud cover or dense vegetation can obstruct remote sensing data, reducing its accuracy. LiDAR is limited by its line-of-sight, meaning it cannot measure objects hidden or obscured by other objects. Additionally, both technologies require expertise in data analysis and interpretation to extract meaningful information.
