Wiser has a  long history of collecting and delivering large and small scale aerial imagery. Our experience includes both analytical and softcopy aero-triangulation along with softcopy feature compilation and extraction.

Wiser has experience producing geo-rectified digital orthophotography for county-wide and city-wide mapping projects and for highway and utility corridors.

Our expert staff continuously improves the quality and efficiency of production, by modifying the automatically generated seam-lines to avoid situations that would otherwise lead to errors in the imagery, resulting in higher quality orthophotography in less time than normal.

Aerial lidar

Light Detection and Ranging (lidar) is a proven approach to creating fast and accurate terrain models for applications in many types of industries. The technology is based on a scanning laser combined with both GPS and inertial technology to create a three dimensional set of points (point cloud).

We specialize in processing high density lidar Data Sets to create a number of survey grade mapping products:

  • Digital Elevation Models (DEM)
  • Digital Terrain Models (DTM)
  • Contours of varying intervals
  • Planimetric Mapping
  • Ortho-rectification in combination with imagery

Acquisition Platforms
  • Fixed Wing Aircraft
  • Helicopter
  • UAV
example applications
  • Corridor Mapping: Roadway, Power Line, Railway Track, and Pipeline Inspection
  • Precision Agriculture
  • Topography in Open-Pit Mining
  • Terrain and Feature Data Mapping
  • Construction-Site Monitoring
  • Mine Planning and Engineering
  • Land-Use Planning
  • Urban Change Detection
