Agenda
! “Roads” in Western Canada ! The problems with roads ! Using FME to remove roads ! Testing the process

Western Canada DLS Grid
! ~1,500,000 km2 (or about 10 Englands) ! ~10,000,000 polygons
![Page 5: Roads? Where We’re Going, We Don’t Need Roads](https://reader033.fdocuments.net/reader033/viewer/2022042613/5478ac69b4af9fa0158b45fc/html5/thumbnails/5.jpg)

Defintion: “Road Allowance”
! 20m or 30m separation between sections ! Surveyed sections from 1871 to 1880 all have
road allowances ! Surveyed sections after 1881 reduced by half the
number of East/West road allowances ! Not all road allowances have a constructed road

First Pass

for performance
