PDP also works from historical aerial imagery to
identify areas of interest. They can estimate a
location from the imagery and then use Catalyst to
navigate to the spot in the field. On-site examination
and sensor readings can then pinpoint the location
of abandoned underground tanks or other sources
of contamination. Catalyst supports additional PDP
projects including well monitoring, wetland ecology
and geotechnical assessments.
In addition to locations, Catalyst provides positioning
metadata that PDP stores with each dataset. The
information enables PDP to enhance the quality
of their services by documenting the time and
accuracy of the GNSS positioning. "The added data
helps us demonstrate a high level of innovation and
performance to our clients," Darling said.
