Included is very dense distance data measured with a digitally calibrated wheel, features (signs, culverts, rails), and 30,000 mile-points. I am somewhat overwhelmed by the plethora of transportation data models and Online documentation, which seems more targeted for municipal tranportation (we're in the sticks here!). What would be a good ESRI resource I can start with, where I can trim out all of the "bling" except for lines, routes, and events? One issue is that while no expense was spared on accurately measuring distance, apparantly we got a discount on the GPS attached to the wheel. We pulled centerlines from 6 in air photo, but the event points matched to the event measurements range from 1 ft to 20 ft from the road centerline. With snapping, this shouldn't be much of an issue except at the start and end points of each road segment, where this is a horizontal shift left or right, as well as a linear shift either a few feet before the segment start, or a few feet after it starts. What would be the best way to correct this (as best as possible without manually shifting 30,000 points). Thanks for any direction.</SPAN></BODY></HTML> Fri, 24 Aug 2012 15:36:50 GMT https://community.esri.com/t5/transportation-questions/where-to-start-with-linear-referencing/m-p/296188#M973 ThomasColson 2012-08-24T15:36:50Z Re: Where to start with Linear Referencing? https://community.esri.com/t5/transportation-questions/where-to-start-with-linear-referencing/m-p/296189#M974 <HTML><HEAD></HEAD><BODY><SPAN>Not sure if this is helpful.&nbsp; You should be able to snap your mile points to your center lines like you said.&nbsp; I would give the center lines estimated mile points (Start/End) and create a route in the Linear Referencing ToolBox.&nbsp; Then used the snapped mile points and center lines to Calibrate the Route under the Linear Referencing ToolBox.&nbsp; Your center line mile points (M Values) would then match the ones you collected.&nbsp; You can then dynseg all your signs and rail crossings to your center lines.</SPAN></BODY></HTML> Mon, 27 Aug 2012 12:55:41 GMT https://community.esri.com/t5/transportation-questions/where-to-start-with-linear-referencing/m-p/296189#M974 BrianYoung1 2012-08-27T12:55:41Z
