What is LRS?
Method for locating assets
along linear facilities
Distinguishes positionfromlocation
- Positionrepresents an XYcoordinate on a map
- Locationrepresents a distance
along a linear feature
Most highway departmentsmethod of choice formanaging asset data

Highway data is managed using linear referencing
A route reference and a
measure value

Highway data is managed using linear referencing
A route reference and a
measure value
One measure createspoint events
Two measures createline events

Dynamic Route Representations
Routes are defined in the data model
Dynamic routes are real features that aremanaged as tabular data
Dynamic route live in the map

Time Aware LRS
Present We need to see the current
state of our highways
Past We need to see what our highwayslooked like when incidents occurred
Future We need the ability to addplanned highways to our data

Esri Roads and Highways manages location
Four possible things
that happen toevents.
-

Esri Roads and Highways manages location
1. The event moves
(preserves location)
-
8/2/2019 tw_1069
26/38
Esri Roads and Highways manages location
1. The event moves
2. The event stays put(preserves position)
-
8/2/2019 tw_1069
27/38
Esri Roads and Highways manages location
1. The event moves
2. The event stays put
3. The event goesaway (preserves
both location andposition)

Esri Roads and Highways manages location
1. The event moves
2. The event stays put
3. The event goesaway
4. The snaps toanother route(preservesproportion)
