lIGHT dETECTION & rANGING (lIdAR)

Orthophotography

Hyperspectral Imaging

Oblique Imagery/Full motion video

LiDAR is a proven technology used to create fast and accurate point clouds for applications in many types of industries.  The technology is based on a laser scanner combined with both GPS and inertial technology to create a three dimensional set of points that include latitude, longitude and elevation for each point in the LiDAR generated point cloud at a minimum.

 

LiDAR can be used to create a number of mapping products for its end user such as:

  • Digital Elevation Models (DEM)
  • Digital Terrain Models (DTM)
  • Contours of varying intervals
  • Slope maps
  • Planimetric mapping
  • Tree height analysis
  • Ortho-rectification in combination with imagery

An orthophoto or orthoimage is an aerial photograph or image geometrically corrected ("orthorectified") so that the scale is uniform.  Orthophotographs are commonly used in Geographic Information Systems (GIS) as a "map accurate" background image.

Hyperspectral imaging, like other spectral imaging, collects and processes information from across the electromagnetic spectrum.  The goal of hyperspectral imaging is to obtain the spectrum for each pixel in the image of a scene with the purpose of finding objects, identifying materials, or detecting processes.  Certain objects leave unique "fingerprints" in the electromagnetic spectrum.  Known as spectral signatures, these "fingerprints" enable identification of the materials that make up a scanned object.

 

Common uses of airborne Hyperspectural imaging include:

  • Mineral/Petroleum exploration
  • Precision Agriculture
  • Waste category and sorting
  • Terrain/Vegetation/Urban Characterization
  • Counter explosive and IED

Oblique imagery is imagery captured at an angle to provide a natural perspective, making objects easier to recognize and interpret.  Oblique aerial images are captured from a 360 degree view of each target.  Each pixel is georeferenced, resulting in intelligent images that give users the ability to interact with the image to measure and extract data.

Infrared Imagery/ Full Motion Video

NDVI / Precision Agriculture

Geospatial Processing & Analysis

Aerial Targets & Ground Control

Airborne infrared imaging is a method used to detect and map a wide variety of events using airborne infrared sensors. This is a useful and very versatile technology utilized by the commercial and defense sectors alike.

 

Uses for Infrared:

  • High voltage line inspection
  • Industrial surveys
  • Detection and inspection of natural geothermal activity
  • Detection of certain vegetation and minerals
  • Law enforcement tasks
  • Anti-poaching
  • Border surveillance
  • Search & rescue operations (SAR)
  • Military reconnaissance to search and track vehicles, vessels, etc.

NDVI (Normalized Difference Vegetation Index) is a common measure in remote sensing for agriculture. It captures how much near infrared light is reflected compared to visible red, green and blue images. NDVI shows you the amount of photosynthesis in plants.  It helps differentiate bare soil from grass or forest, detect plants under stress, and differentiate between crops and crop stages. Whole-field, in-season,  and current condition data are the most valuable pieces of information in a precision program. Problems can be identified early and appropriate interventions can be rapidly selected.

 

By using crop airborne remote sensing to observe, measure, and respond to variability in individual plants, clients can target areas requiring attention. By pinpointing these areas, our customers  can provide care only where needed—improving yield, conserving resources,  assessing loses and avoiding waste.

 

  • Crop Health Imaging
  • Mid-Field Weed Identification
  • Variable-Rate Fertility
  • Irrigation Equipment Monitoring
  • Increase Yields
  • Save Time

We conduct spatial data processing using industry standard tools, technologies and techniques. Spatial data processing utilizes large volumes of geodata to answer questions, identify risk and solve critical problems in a variety of industries.

 

We conduct comprehensive analysis of geospatial data in order to paint the big picture. We gather, display, and manipulate aerial imagery, LIDAR, Hyperspectral, Infrared, GPS, satellite photography, and historical data to analyze and create intelligent and actionable products.  Spatial data processing can be very resource intensive and complex since it usually involves the analysis of large amounts of spatial and non-spatial data from various diverse sources and can additionally incorporate the dimension of time.

 

  • Defense
  • Homeland Security
  • Law Enforcement
  • Emergency Management
  • Mapping
  • Mining
  • Earthwork
  • Forensics
  • Inspection
  • BIM
  • Agriculture

We set aerial targets for mapping and surveying projects that are placed on predetermined locations within the survey area. We use survey grade GPS base stations and rovers to collect target locations. This assists in post processing and the projects spatial accuracy.
