Photogrametry & Access Route Design

Photogrammetry is a science of finding measurements from photographs taken aerially, for recovering distances for positions of surface points with provided fixed reference points.

Access Route Design

With our experienced team of Engineers, Technologists, and Technicians are well versed in providing solutions for access road development. We have experience with photogrammetry and remote  sensing for the following that may be required to find the solutions for the following.

  • Drainage with hydrology studies
  • Aggregate investigations
  • Ditching and culvert design
  • New road locations and cost estimates
  • Airport location studies
  • and other aerial photography applications

With mild winters, water and swamp crossings create problems for winter road operators. We have experience using photogrammetry for route studies of over 200 km of northern winter roads. The study was conducted to find solutions of relocating the winter roads to elevations that were dry.

We have been involved in numerous access road work, from the design, construction, and contract administration of new and even complete reconstruction since 1969. MNR, paper companies and timber operations require low class all weather roads to access, management units and for cutting licences of their areas. The usual process in access road construction involves location of the road using photogrammetry methods, survey of the selected alignment on the field, design with the quantity estimates, contract preparation and the construction administration including all necessary inspections.  Location of available gravel sources and the soils surveys are carried out during the field engineering survey phase of the project.


In 1979, the Ministry of Natural Resources (MNR) started building and funding construction in Northwestern Ontario of approximately 300 km of access roads, including bridges, under the Provincial Government introduced DREE Program. We have been involved in various capacities with the majority of the DREE roads system. Our involvement in access road design and construction has been as early as 2002, with even the design of the last 4.5 km of Flanders Road reconstruction, for Lac La Croix First Nation in the Atikokan area. Additionally, we have provided photogrammetry to find aggregate gravel sources for Stanjikoming First Nations.
