DTM & OGL Checking
N D Oliver & Co Ltd, Chartered Land Surveyors, are experts in the collection, organisation, presentation and delivery of spatial data. The quality of our survey data presentation is a key factor in explaining why over 80% of our work is repeat business. Our clients get what they need and they keep coming back for more.
DTM, DEM, DGM, OGL, FGL are all essentially Ground Models. They define the shape of a surface, whether a design surface or a surface created as a result of a survey. DTM & OGL checking is becoming increasingly valuable. Surface designs are becomingly increasingly complicated to set out and check.
The ability to accurately check & compare the levels of surfaces has implications for:
design and tendering
» if a client provides you with an original ground survey for design or tendering purposes why not check it before you go any further
>we can put that OGL onto either a total station or GPS. The screen will show you cut & fill anywhere on site
>volume differences and drawings can be produced in the office
during the job
» avoid taking away too much or bringing in too much
>with the various design surfaces loaded we can in real-time see the cut & fill with respect to a surface simply by standing at any point on the site
>setout profiles at any location with reference to any surface
» record what you have done
>we can carry out weekly or daily measures indicating cut & fill
>variations can be agreed, recorded and volumes computed
at the end of a project
» to compare the actual re-instatement with the design for the re-instatement by standing anywhere on the site
