land development civil engineering and resource industries headquarters north vancouver bc area served global 1 products software website homepage softree technologies is a north vancouver bc 2 based company that develops software for the forestry civil engineering and energy industries . contents 1 roadeng 2 terrain tools 3 softree optimal 4 references 5 external links 6 see also roadeng edit roadeng is the original software program developed by softree technologies with early adopters including government agencies like the usda forest service . 3 early versions of the software had three modules road notes where a surveyor enters their field notes grade design and plan view . 4 the program is a forest road design system that allows people to easily determine where the best extraction paths would be for timber or other wilderness based primary resources especially the alignment of the roads needed for the extraction of the resource and the insertion of the machinery needed to extract it . it utilizes 3d approximations of the environment and allows individuals to pre plan their projects . 5 it is able to accept data produced by hand by surveyors or produce approximations based upon other variables . 6 terrain tools edit terrain tools is a civil engineering software product that is available for professional engineers but also targets the userbase of individual researchers or small budget groups with a freeware version of its software . it accepts survey data into its program in order to plot coordinates visually and statistically for the user . 7 softree optimal edit softreeoptimal is a mathematical technique to automatically determine the lowest cost vertical alignment for corridor based infrastructure projects such as roads pipelines and railways . it was developed by the university of b.c. and softree technical systems inc in 2012 based on a mixed integer programming model . softreeoptimal accounts for excavation grading and material movement costs while matching user criteria such as design speed cross section configuration and horizontal alignment softreeoptimal uses a new patent pending mathematical optimization methodology which guarantees optimality while accounting for detailed design conditions . 8 9 references edit about us small is beautiful . retrieved september 17 2013 . softree introduces roadeng version 5 . north
